proceedings against Khalid after he was convicted of conspiring to 1
provide material support for terrorism in violation of 18 U.S.C. § 2
2339A. Khalid moved to terminate his removal proceedings, 3
contending that he derivatively acquired citizenship from his U.S. 4
citizen father. At the time Khalid’s father became a U.S. citizen, Khalid 5
had recently entered federal pretrial juvenile detention for terrorism‐ 6
related charges, and remained there for the short time until his 7
eighteenth birthday. As a result, the IJ and BIA concluded that Khalid 8
was not in the “physical custody” of his U.S. citizen parent before his 9
eighteenth birthday, as required by the applicable derivative 10
naturalization statute, 8 U.S.C. § 1431(a). We hold that the short, 11
temporary physical separation caused by Khalid’s time in federal 12
pretrial juvenile detention did not strip Khalid’s father of his 13
“physical custody” of Khalid as that term is used in 8 U.S.C. § 1431(a), 14
and that consequently, Khalid is a U.S. citizen. Accordingly, we 15

D RONEY , Circuit Judge: 1
Under the Immigration and Nationality Act (INA), a child 2
under the age of eighteen who is a legal permanent resident (LPR) of 3
the United States acquires citizenship when that child’s parent 4
becomes a U.S. citizen if the child is residing in the United States in 5
the “legal and physical custody” of the citizen parent. 8 U.S.C. § 6
1431(a). In this petition, we are asked to construe the term “physical 7
custody” in 8 U.S.C. § 1431(a) as it applies to the unique situation 8
presented here. 9
In July 2011, the FBI arrested Petitioner Mohammed Hassan 10
Faizan Khalid for allegedly conspiring to provide material support 11
for terrorism in violation of 18 U.S.C. § 2339A. At the time, Khalid was 12
a minor and a legal permanent resident of the United States. The 13
United States District Court for the Eastern District of Pennsylvania 14
placed Khalid in pretrial juvenile detention following his arrest. 15
Shortly thereafter, in August 2011, Khalid’s father became a U.S. 16

-- 4 of 42 --

5
citizen, while Khalid was still under the age of eighteen. A month 1
later, Khalid turned eighteen while still in federal pretrial juvenile 2
detention. During Khalid’s subsequent removal proceedings, the IJ 3
and the BIA concluded that Khalid’s detention had terminated his 4
father’s “physical custody” over Khalid, and therefore Khalid was not 5
eligible to acquire derivative citizenship under 8 U.S.C. § 1431(a). 6
We disagree and hold that Khalid’s temporary physical 7
separation from his father while in federal pretrial juvenile detention 8
did not terminate Khalid’s father’s “physical custody” of Khalid. We 9
construe the term “physical custody” in 8 U.S.C. § 1431 by first 10
looking to state law definitions of that term. Those definitions provide 11
some direction and indicate that a parent’s physical custody of a child 12
does not cease due to a child’s brief, temporary separation from a 13
parent. Second, the statutory context and history of the derivative 14
citizenship statute indicate that the “physical custody” requirement 15
ensures that the LPR child has a strong connection to the naturalizing 16

-- 5 of 42 --

6
parent and to the United States at the time the child becomes eligible 1
for derivative citizenship. Khalid had those connections. Third, the 2
applicable canons of statutory interpretation also favor construing the 3
term “physical custody” so that such custody does not terminate 4
upon a brief, temporary separation from a parent. Finally, the 5
distinctive nature of federal pretrial juvenile detention—which 6
encourages continued family involvement with the child during such 7
detention—further supports the conclusion that Khalid’s father 8
retained “physical custody” over Khalid for the purposes of 8 U.S.C. 9
§ 1431(a). As a result, Khalid is a U.S. citizen and the Department of 10
Homeland Security (DHS) must terminate removal proceedings 11
against him. 12
BACKGROUND 13
Petitioner Mohammed Hassan Faizan Khalid entered the 14
United States with his family as an LPR in 2007. He was born in the 15
United Arab Emirates, but as the child of two Pakistani parents, he 16

-- 6 of 42 --

7
was a Pakistani citizen. From at least the summer of 2009, when he 1
was 15 years old, until his arrest in July 2011 at age 17, Khalid used 2
the internet to attempt to assist extremists in the United States and 3
abroad. According to the government, Khalid helped with 4
recruitment efforts by translating jihadist videos from Urdu into 5
English, and then posting those videos online. In addition, Khalid 6
assisted a co‐defendant who aspired to commit jihad in Europe by 7
attempting to fundraise for that co‐defendant and by concealing 8
evidence from the FBI. 9
Federal agents arrested Khalid on July 6, 2011. At the time he 10
was arrested, Khalid was seventeen years old, had just graduated 11
from high school, and was living at home with his parents in 12
suburban Baltimore. Following his arrest, Khalid was detained at the 13
Berks County Youth Correctional Center (ʺBerksʺ) in Berks County, 14
Pennsylvania. Shortly thereafter, a federal district judge ordered 15

-- 7 of 42 --

8
Khalid’s continuing detention at that facility pursuant to 18 U.S.C. §§ 1
50345035, which governs federal pretrial juvenile detention. 2
A little over a month after his arrest, on August 17, 2011, 3
Khalid’s father became a U.S. citizen. At the time Khalid’s father 4
naturalized, Khalid was still detained at Berks. The government 5
transferred Khalid to an adult facility that October, after Khalid 6
turned eighteen years old. 7
Khalid cooperated extensively with the government following 8
his arrest. He met with federal investigators over twenty times and 9
testified in grand jury proceedings for two investigations. The 10
government acknowledged that “Khalid’s assistance advanced 11
multiple national security investigations in important ways.” AR 12
538.1 Khalid pleaded guilty to violating 18 U.S.C. § 2339A, but because 13
of his cooperation, the government requested a downward departure 14
from Khalid’s recommended Guidelines sentence of fifteen years’ 15
1 We use “AR” as shorthand for the administrative record.

-- 8 of 42 --

9
imprisonment. The district court sentenced Khalid to five years’ 1
imprisonment, which he has served.2 2
In late 2015, after Khalid served his sentence, the government 3
transferred him to the custody of Immigration and Customs 4
Enforcement, and the DHS commenced removal proceedings against 5
Khalid based upon his conviction. Khalid moved to terminate the 6
removal proceedings on the ground that he is a U.S. citizen by virtue 7
of his father’s naturalization, see 8 U.S.C. § 1431(a), and, in the 8
alternative, sought deferral of removal under the Convention Against 9
Torture, see 8 C.F.R. § 1208.17(a). 3 The IJ denied the motion to 10
terminate in April 2016, concluding that Khalid was not in his father’s 11
“physical custody” at the time his father naturalized. In September 12
2 At oral argument, counsel for the government indicated that he had no
information indicating that Khalid presents a continuing threat to the United
States.
3 DHS sought removal to the United Arab Emirates or Pakistan. Khalid maintained
that he would be tortured if removed to Pakistan because of his cooperation in the
federal terrorism investigations.

-- 9 of 42 --

10
2016, the BIA affirmed the IJ’s decision, holding that a “child must 1
reside with the citizen parent to satisfy the ‘physical custody’ 2
requirement of [8 U.S.C. § 1431(a)(3)].” AR 6. Khalid now petitions for 3
review of the BIA’s decision, arguing that DHS may not remove him 4
because he is a U.S. citizen.4 5
DISCUSSION 6
I. Jurisdiction and Standard of Review 7
Khalid presents one question for review: whether he was in the 8
“physical custody” of his father under 8 U.S.C. § 1431(a) at the time 9
his father naturalized. That issue is a question of law that we have 10
jurisdiction to review. 8 U.S.C. § 1252(a)(2)(D); Xiao Ji Chen v. U.S. 11
Dep’t of Justice, 471 F.3d 315, 32628 (2d Cir. 2006). In addition, we 12
have jurisdiction pursuant to 8 U.S.C. § 1252(b)(5)(A) because Khalid 13
claims that he is a United States citizen and no dispute of fact prevents 14
4 The IJ also granted Khalid deferral of removal as to Pakistan, but not as to the
United Arab Emirates.

-- 10 of 42 --

11
our resolution of that question. We review de novo the BIA’s 1
interpretation of a citizenship statute. See Jaen v. Sessions, 899 F.3d 182, 2
185‐86 n.2 (2d Cir. 2018). 3
II. The Text, Context, and Statutory History of 8 U.S.C. § 1431(a) 4
To determine whether Khalid satisfies the “physical custody” 5
requirement in this context, we first look to the text of the statute. See, 6
e.g., Life Techs. Corp. v. Promega Corp., 137 S. Ct. 734, 739 (2017). If the 7
statute is ambiguous, then “we may resort to canons of statutory 8
interpretation to resolve the ambiguity.” Tanvir v. Tanzin, 894 F.3d 9
449, 459 (2d Cir. 2018). We determine whether a statute is ambiguous 10
“by reference to the language itself, the specific context in which that 11
language is used, and the broader context of the statute as a 12
whole.” Robinson v. Shell Oil Co., 519 U.S. 337, 341 (1997). Here, we 13
begin that inquiry by first examining the text of the statute itself, and, 14
concluding that the term “physical custody” is not entirely clear, we 15
then turn to the broader statutory context and its history. 16

-- 11 of 42 --

12
a. “Physical Custody” and State Law Guidance 1
Under 8 U.S.C. § 1431, a child may derive U.S. citizenship from 2
a parent if (1) one parent is a citizen, (2) the child is “under the age of 3
eighteen years,” and (3) “[t]he child is residing in the United States in 4
the legal and physical custody of the citizen parent pursuant to a 5
lawful admission for permanent residence.” 8 U.S.C. § 1431(a). 5 6
Neither party here disputes that the statute uses the term “physical 7
custody” in the family law sense of the term. 6 Nevertheless, the 8
government suggests that we should only interpret this term with 9
reference to federal law and BIA precedents interpreting terms other 10
than “physical custody.” We agree with the government that 11
“naturalization laws must ‘be construed according to a federal, rather 12
than state, standard.’” Brissett v. Ashcroft, 363 F.3d 130, 133 (2d Cir. 13
5 There is no dispute that Khalid’s father and mother shared legal custody of
Khalid at all relevant times, and that both parents were living together with Khalid
and his siblings in Maryland until Khalid’s arrest.
6 The parties also do not dispute that Khalid satisfies the remaining requirements
for citizenship.

2004) (quoting Nehme v. INS, 252 F.3d 415, 42223 (5th Cir. 2001)). 1
However, “[i]t is [also] a cardinal rule of statutory construction that, 2
when Congress employs a term of art, it presumably knows and 3
adopts the cluster of ideas that were attached to each borrowed word 4
in the body of learning from which it is taken.” Citizens Against Casino 5
Gambling in Erie Cty. v. Chaudhuri, 802 F.3d 267, 287 (2d Cir. 2015) 6
(quoting Air Wis. Airlines Corp. v. Hoeper, 571 U.S. 237, 248 (2014)). 7
In this case, that “cardinal rule” compels us to examine state 8
law definitions of “physical custody” to help construe that term and 9
the “cluster of ideas” attached to it. Id. Family law, after all, is an area 10
of law that federal courts and Congress leave almost exclusively to 11
state law and state courts. See, e.g., Reno v. Flores, 507 U.S. 292, 310 12
(1993) (noting that states have “special proficiency in the field of 13
domestic relations, including child custody” (internal quotation 14
marks omitted)); Ankenbrandt v. Richards, 504 U.S. 689, 70104 (1992) 15
(discussing domestic relations exception to federal diversity 16

-- 13 of 42 --

14
jurisdiction for cases involving divorce, alimony, and child custody 1
decrees). This approach to statutory interpretation of such a term is 2
well‐grounded in our precedent and that of the Supreme Court. For 3
example, we have looked to state law definitions to define the term 4
“legal custody” in the prior version of the derivative citizenship 5
statute at issue in this case. See Garcia v. USICE (Dep’t of Homeland Sec.), 6
669 F.3d 91, 95 (2d Cir. 2011). Indeed, we observed in Garcia that “we 7
often look to state law for a rule of decision where there is no extant 8
body of federal common law in the area of law implicated by the 9
statute.” Id. (alterations and internal quotation marks omitted); see also 10
Miss. Band of Choctaw Indians v. Holyfield, 490 U.S. 30, 47 (1989) (“That 11
we are dealing with a uniform federal rather than a state definition 12
does not, of course, prevent us from drawing on general state‐law 13
principles to determine the ordinary meaning of the words used.” 14
(internal quotation marks omitted)). 15

-- 14 of 42 --

15
Consistent with these principles, we turn to state law 1
definitions of “physical custody” in the family law context to help us 2
understand how Congress intended to use that term in 8 U.S.C. § 3
1431. 4
The parties disagree about the guidance that state law offers. 5
The government, consistent with the BIA, contends that a child must 6
be “actually resid[ing]” with the citizen parent at the exact time of the 7
parent’s naturalization or before the child’s eighteenth birthday to 8
satisfy this requirement. Resp’t Br. 1920. In contrast, Khalid argues 9
that “physical custody” describes only the “legal relationship 10
between parents and minor” children. Pet’r Br. 10. Both arguments 11
find some support in state law, and as a result, we do not find state 12
law conclusive in defining that term. 13
State family law definitions of the term “physical custody” are 14
often at odds with the government’s assertion that a child must be 15
“actually resid[ing]” with a parent for the child to be in that parent’s 16

-- 15 of 42 --

16
“physical custody.” For example, physical custody can be split 1
between parents, and two parents can share and retain “physical 2
custody” even if the child does not actually reside in any one parent’s 3
home full‐time. See, e.g., Loran v. Loran, 2015 WY 24, ¶ 17 n.3, 343 P.3d 4
400, 404 n.3 (Wyo. 2015) (listing cases addressing shared physical 5
custody in Wyoming); Jarvis v. Jarvis, 1998 ND 163, ¶¶ 3437, 584 6
N.W.2d 84, 92 (discussing split physical custody arrangements); 7
Child Custody Prac. & Proc. § 4:34 (“When choosing between parents, 8
the court may award sole or exclusive custody to one parent, joint 9
legal and/or physical custody, or divided custody with each parent 10
having physical custody of one or more children.”). Those uses of the 11
term “physical custody” conflict with the government’s argument 12
that Khalid must have been “actually residing” with his father at the 13
time he naturalized or before the short time until his eighteenth 14
birthday to obtain derivative citizenship. 15

-- 16 of 42 --

17
Further, Khalid is correct that the term “physical custody” is 1
often used to define a legal relationship between the child and parent. 2
Indeed, in the state where Khalid lived with his family prior to his 3
detention and conviction, “[p]hysical custody . . . means the right and 4
obligation to provide a home for the child and to make the day‐to‐day 5
decisions required during the time the child is actually with the 6
parent having such custody.” Taylor v. Taylor, 508 A.2d 964, 967 (Md. 7
1986) (emphasis added); see also Henderson v. Henderson, 568 P.2d 177, 8
179 (Mont. 1977) (“‘Physical custody’ is not limited to having actual, 9
immediate control of the physical presence of the child. Rather, this 10
phrase relates to the custodial rights involved in the care and control 11
of the child.”). Similarly, state courts also employ the term “physical 12
custody” to describe a right that they “award” to parents disputing 13
who may control a child’s decisions and provide care to that child. 14
See, e.g., Nolte v. Mehrens, 648 N.W.2d 727, 731 (Minn. 2002) 15
(explaining requirements for “award[ing] physical custody”); Child 16

-- 17 of 42 --

18
Custody Prac. & Proc. § 4:34; Custody; Black’s Law Dictionary (10th ed. 1
2014) (defining custody as “[t]he care, control, and maintenance of a 2
child awarded by a court to a responsible adult,” and stating that 3
“[c]ustody involves legal custody (decision‐making authority) and 4
physical custody (caregiving authority), and award of custody grants 5
both rights”). 6
As we noted, the BIA’s decision in this matter interprets 7
“physical custody” to require that Khalid have “actually resided” 8
with his father in the two‐month window between his father’s 9
naturalization and Khalid’s eighteenth birthday. The government 10
does have some support for this position. For example, the Uniform 11
Child Custody Jurisdiction and Enforcement Act (UCCJEA) defines 12
“physical custody” as “the physical care and supervision of a child.” 13
UCCJEA § 102(14). That definition seems to require a parent’s 14
physical presence with the child. In addition, state courts do 15
sometimes deem residing with a parent a component of “physical 16

-- 18 of 42 --

19
custody.” See, e.g., In re AJR, 852 N.W.2d 760, 765 (Mich. 2014) (noting 1
that “physical custody pertains to where the child shall physically 2
reside” in interpreting Michigan’s child custody laws (alteration 3
omitted) (internal quotation marks omitted)); Rivero v. Rivero, 216 4
P.3d 213, 222 (Nev. 2009) (“Physical custody involves the time that a 5
child physically spends in the care of a parent. During this time, the 6
child resides with the parent and that parent provides supervision for 7
the child and makes the day‐to‐day decisions regarding the child.”). 8
On balance, the state law uses of the term “physical custody” 9
are inconclusive in defining that term in 8 U.S.C. § 1431(a). However, 10
we emphasize that many of the state law uses of the term “physical 11
custody” conflict with the BIA’s requirement that a “child must reside 12
with the citizen parent to satisfy the ‘physical custody’ requirement 13
of [8 U.S.C. § 1431(a)(3)],” as it applied that rule in this case. AR 6. The 14
BIA’s decision reduces “physical custody” to an “actual residency” 15
requirement at some point after the citizen parent naturalizes, but 16

-- 19 of 42 --

20
before the child’s eighteenth birthday—even in cases involving short, 1
temporary separations, like this one. State law rarely uses such a 2
narrow definition of physical custody, and we do not think that 3
“physical custody” is determined exclusively by the small moment in 4
time immediately following a citizen parent’s naturalization, even 5
when looking to state law for guidance. However, given the variety 6
of definitions under state law, we conclude that the plain text itself 7
does not clarify what constitutes “physical custody” under 8 U.S.C. § 8
1431. Accordingly, we turn to other indicators of the statute’s 9
meaning to help construe and apply that term in this case.7 See, e.g., 10
7 The government also argues that “in the legal and physical custody of the citizen
parent” is a “limiting phrase” that “grammatically must refer” to the antecedent
“the child is residing” in § 1431(a)(3). Resp’t Br. 26. While this may be true,
“physical custody” is a term of art, and the state law definitions we surveyed
above make clear that in some contexts, a parent might “have” physical custody
or a child might be residing “in” a parent’s physical custody, even if that child is
not currently physically present with the parent. Such “ordinary meaning[s]” of
“physical custody” do not limit the statute in the way the government argues.
Holyfield, 490 U.S. at 47. As a result, we do not think the government’s grammatical
argument affects the outcome of this petition. A term of art does not lose its
meaning simply because of the verb that it modifies.

words [of a statute] in their context and with a view to their place in 5
the overall statutory scheme.” (internal quotation marks omitted)). 6
b. The Statutory Context and History 7
Congress enacted the current version of the derivative 8
citizenship statute with the passage of the Child Citizenship Act of 9
2000 (“CCA”). See Child Citizenship Act of 2000, Pub. L. 106‐395, 114 10
Stat. 1631 (2000) (codified in part at 8 U.S.C. § 1431). That Act 11
significantly amended the derivative citizenship statute by 12
“liberaliz[ing] the Immigration and Nationality Act’s conditions for 13
the automatic derivative naturalization of alien children of United 14
States‐born or naturalized parents.” Drakes v. Ashcroft, 323 F.3d 189, 15
190 (2d Cir. 2003) (per curiam). In particular, and as relevant here, the 16

-- 21 of 42 --

22
statute modified the derivative citizenship conditions for LPR 1
children with married LPR parents, making it easier for those children 2
to obtain citizenship when a parent naturalizes. The new “physical 3
custody” requirement ensures that a child’s “real interests” are in the 4
United States when obtaining derivative citizenship because the child 5
has a strong connection to the naturalizing parent. Duarte‐Ceri v. 6
Holder, 630 F.3d 83, 90 (2d Cir. 2010) (quoting Bustamante–Barrera v. 7
Gonzales, 447 F.3d 388, 397 (5th Cir. 2006)). In other words, Congress 8
sought to make derivative citizenship more available to the children 9
of married parents, while still ensuring a connection between the 10
naturalizing parent and child. 11
As we detail below, those changes to the statute further support 12
our conclusion that Khalid satisfies the “physical custody” 13
requirement of 8 U.S.C. § 1431 in this case. To explain this 14
understanding, we look first at the immediate changes that the CCA 15
brought to derivative citizenship, and second, we examine the 16

-- 22 of 42 --

23
broader statutory context and history of derivative citizenship for 1
minor children. 2
The CCA made it easier for LPR children to obtain derivative 3
citizenship by requiring that only one of their parents naturalizes. As 4
the House Committee on the Judiciary Report for the CCA notes, 5
under the relevant prior derivative citizenship law, a foreign‐born 6
child with non‐citizen parents could only become a citizen (1) when 7
“both parents naturalize” or (2) where the parents had divorced or 8
separated and the U.S. citizen parent had custody of the child. See 9
H.R. Rep. No. 106‐852, at 4 (2000); see also 8 U.S.C. § 1432(a) (“A child 10
born outside of the United States of alien parents . . . becomes a citizen 11
of the United States upon fulfillment of the following conditions: (1) 12
The naturalization of both parents; or . . . (3) The naturalization of the 13
parent having legal custody of the child where there has been a legal 14
separation of the parents . . . .”), repealed by § 103 of the Child 15
Citizenship Act of 2000. The revised derivative naturalization statute 16

(as amended by the CCA) provides that only one parent needs to 1
become a citizen for the non‐citizen child to automatically derive 2
citizenship, as long as the naturalized parent has “legal and physical 3
custody” of the child and the child is residing in the United States. See 4
8 U.S.C. § 1431(a); H.R. Rep. No. 106‐852, at 5. That one parent 5
requirement applies regardless of whether the parents are separated, 6
unlike the prior version of the statute. Accordingly, the CCA enabled 7
a child with married parents (who are not separated) to acquire 8
derivative citizenship if only one parent naturalized. 9
In addition, the prior version of the statute mentioned 10
“custody” only in cases involving separated parents. See 8 U.S.C. § 11
1432(a)(3), repealed by § 103 of the Child Citizenship Act of 2000. In 12
such cases, the statute granted citizenship to the child so long as the 13
child was in the “legal custody” of the naturalizing parent. Id. A child 14
in the legal custody of the non‐naturalizing parent, however, would 15
not acquire citizenship. Id. 16

25
Congress added the words “physical custody” to the statute for 1
the first time with the CCA. In doing so, Congress imposed a custody 2
requirement for the first time in the context of married parents. When 3
compared against the prior version of the statute, those changes 4
indicate that the new custody provision ensures that the child’s “real 5
interests” are in the United States because of the child’s strong 6
connection to the naturalizing parent. Duarte‐Ceri, 630 F.3d at 90. 7
Under the former automatic derivative citizenship statute, ensuring 8
that the child’s “real interests” were in the United States through the 9
child’s connection to the U.S. citizen parent was less of a concern 10
because the prior version of the statute required that both LPR parents 11
naturalize or (if the parents were separated) that the child had a strong 12
connection with the naturalizing parent (through the “legal custody” 13
requirement). Similarly, the CCA now requires that a child’s “real 14
interests” are in the United States by ensuring that in cases of married 15
(even if physically separated) parents, the child only acquires 16

-- 25 of 42 --

26
citizenship if in the custody of the naturalizing parent. See 8 U.S.C. § 1
1431; Duarte‐Ceri, 630 F.3d at 90. 2
That conclusion—that “physical custody” helps ensure that a 3
child’s “real interests” are in the United States because of the 4
connection to the U.S. citizen parent—fits within both past BIA 5
precedent and the broader statutory context and history. See Duarte‐ 6
Ceri, 630 F.3d at 90. First, under the prior version of the statute, this 7
Court and the BIA looked to which parent had “actual, uncontested 8
custody,” in cases of legally separated parents, because the parent 9
with that actual, uncontested custody was “the parent with ‘legal 10
custody’ for the purpose of evaluating [a] derivative citizenship 11
claim.” Garcia, 669 F.3d at 96; see also Matter of M
, 3 I. & N. Dec. 850 12
(BIA 1950) (“[I]n the absence of judicial determination or judicial or 13
statutory grant of custody in the case of legal separation of the parent 14
of a person claiming citizenship under section 314(c) [(8 U.S.C. § 15
1432(a)’s predecessor)], the parent having actual uncontested custody 16

-- 26 of 42 --

27
is to be regarded as having ‘legal custody’ of the person concerned for 1
the purpose of determining that person’s status under section 2
314(c).”). The effect of this inquiry was to ensure that a child only 3
became a U.S. citizen where the naturalizing parent had a true 4
connection to and control of the child, and to deny the child 5
citizenship if the child had little actual relationship with the 6
naturalizing parent. 7
Furthermore, the CCA replaced a statute that federal courts 8
had long interpreted as seeking to ensure that children acquiring 9
derivative citizenship have their “real interests” in the United States. 10
Duarte‐Ceri, 630 F.3d at 90. As the Fifth Circuit has explained, in 11
enacting the precursor to the current CCA, “Congress explicitly 12
required the naturalization of both parents [for the child to 13
naturalize], unless the parents had been legally separated and the 14
parent with legal custody obtained naturalization.” Nehme, 252 F.3d 15
at 424. The court further noted that “the overall intent behind the 16

-- 27 of 42 --

28
[precursor to the CCA] was to make it more difficult for aliens to 1
obtain United States citizenship. Congress was concerned about the 2
burden on the United States government and its agencies of 3
protecting persons who were only ‘nominal’ citizens of this country 4
and whose ‘real interests,’ as demonstrated by their residence abroad, 5
was not in the United States.” Id. at 42425 (quoting S. Rep. No. 76– 6
2150, at 4 (1940)); see also id. at 425 (discussing other legislative history 7
sources to demonstrate that Congress wished to ensure that those 8
who acquired citizenship from the United State’s derivative 9
citizenship laws had a real connection to the United States); H.R. Rep. 10
No. 106‐852 at 3 n.1 (reaffirming statute’s purpose of ensuring a 11
citizen’s connection to the United States and noting that the statute’s 12
residency language helps to ensure that that purpose is achieved). 13
This Court has made the same observation about the precursor 14
to the CCA. See Duarte‐Ceri, 630 F.3d at 8990. Indeed, we stated in 15
Duarte‐Ceri that “Congress enacted the [precursor to the 16

-- 28 of 42 --

29
current] derivative citizenship statute to ensure that ‘alien children 1
whose real interests were located in America with their custodial parent, 2
and not abroad, should be automatically naturalized.’” Id. (emphasis 3
added) (quoting Bustamante–Barrera, 447 F.3d at 397). Thus, the 4
history of the derivative citizenship statute supports reading the 5
statute—and the term “physical custody,” in particular—to ensure 6
that a child’s “real interests” are in the United States through a 7
genuine connection between the United States citizen parent and that 8
parent’s child.8 Nothing in either the CCA’s text or history suggests 9
that Congress intended to abandon that requirement in enacting the 10
8 That the statute also requires the non‐citizen child to be residing “in the United
States” does not mean the “physical custody” language is superfluous in assuring
that the child’s “real interests” are in the United States. The requirement that the
LPR child be in the citizen parent’s “physical custody” ensures that in situations
where parents might be physically (but not legally) separated, the child develops
a lasting connection to the United States. The same cannot be said if the child were
in the physical custody of only the non‐naturalizing LPR parent; in that case, the
child might not develop the connection to the United States that the statute seeks
to guarantee because that LPR parent might leave the United States with the child
at some point after the other LPR parent naturalizes.

30
CCA. Indeed, the physical custody provision demonstrates a desire 1
to continue ensuring that purpose is met. 2
As a result, while the statutory context and history does not 3
resolve all the textual ambiguities of the term “physical custody,” it 4
does make clear that Congress intended to ensure a child’s connection 5
to the naturalizing parent. Here, there is no dispute that Khalid had 6
such a connection to his United States citizen father at the time 7
Khalid’s father naturalized. Khalid had lived at home with his parents 8
since entering the United States. Thus, Khalid’s acquisition of 9
derivative citizenship does not violate Congress’s demand that the 10
child has a strong connection to the United States to acquire 11
derivative citizenship. 12
III. Canons of Statutory Interpretation 13
Two canons of statutory interpretation applicable to the CCA 14
also support our conclusion that physical custody under 8 U.S.C. § 15
1431 does not simply end on a brief, temporary separation from the 16

-- 30 of 42 --

31
naturalizing parent. First, the derivative citizenship statute as 1
amended by the CCA promotes “Congress’s remedial purposes” of 2
“keep[ing] families intact.” Duarte‐Ceri, 630 F.3d at 90; see also 3
Nwozuzu v. Holder, 726 F.3d 323, 332 (2d Cir. 2013) (discussing 4
“Congress’s intent to preserve the family unit and to keep families 5
intact” under the previous version of the derivative citizenship 6
provision at issue in this case). While we previously made that 7
observation about the statute’s remedial purpose in connection with 8
8 U.S.C. § 1432, the same observation applies to the amended statute. 9
As we have already noted, the CCA further “liberalizes the 10
Immigration and Nationality Act’s conditions for the automatic 11
derivative naturalization of alien children of United States‐born or 12
naturalized parents.” Drakes, 323 F.3d at 190; see also Pina v. Mukasey, 13
542 F.3d 5, 8 (1st Cir. 2008) (similarly noting the Act’s purpose of 14
liberalizing the conditions for derivative citizenship for children of 15
U.S. citizens). Accordingly, nothing about the CCA affects our 16

-- 31 of 42 --

32
observation in Duarte‐Ceri. Indeed, the statute only further promotes 1
its goal of family unity, even while also continuing to ensure a child’s 2
connection to the United States. 3
Second, there is a “long‐standing presumption” that in “the 4
immigration context,” we construe “‘any lingering ambiguities’ in 5
favor of the petitioner.” Duarte‐Ceri, 630 F.3d at 89 (quoting INS v. 6
Cardoza–Fonseca, 480 U.S. 421, 449 (1987)). The government contends 7
the opposite, arguing that “doubts [about Khalid’s eligibility] should 8
be resolved in favor of the United States and against the claimant.” 9
Berenyi v. Dist. Dir., INS, 385 U.S. 630, 637 (1967) (internal quotation 10
marks omitted). The presumption the government cites, however, 11
applies to evidentiary burdens, and does not dictate how we must 12
resolve the “lingering ambiguities” that exist when interpreting a 13
citizenship statute. See, e.g., Gil v. Sessions, 851 F.3d 184, 188 (2d Cir. 14
2017) (citing Berenyi to support placing burden on petitioner to 15
establish the factual basis for his citizenship). 16

-- 32 of 42 --

33
Those considerations further support our conclusion that 1
Khalid satisfies the physical custody requirement. Duarte‐Ceri 2
compels us to “interpret the statute’s ambiguity with leniency” in a 3
way that “preserves rather than extinguishes citizenship,” given both 4
the statute’s purpose of maintaining family unity and the “lingering 5
ambiguities” as to the text’s meaning. 630 F.3d at 8890. That principle 6
further supports reading “physical custody” not to hinge on the brief 7
and temporary separation created by Khalid’s pretrial detention, 8
when no court had yet adjudicated Khalid guilty of any offense. 9
IV. The Circumstances of Khalid’s Federal Pretrial Juvenile 10
Detention 11
12
We also must conduct an inquiry into the particular custody 13
arrangement at the time the parent naturalizes and the child becomes 14
eligible for citizenship. The BIA made no such inquiry in this matter. 15
Instead, it reached a broad conclusion, declaring that a child must 16
“actually resid[e]” with the U.S. citizen parent “at the time of the 17
[parent’s] naturalization or at some time after he becomes a citizen.” 18

-- 33 of 42 --

34
AR 56. For the reasons we have already explained, we think this 1
interpretation of the statute incorrect. Furthermore, as we explain 2
below, we think that interpretation at odds with the nature of Khalid’s 3
separation from his father in this case. 4
The nature of federal pretrial juvenile detention supports the 5
view that Khalid satisfied the “physical custody” requirement. 6
Congress created the current pretrial detention system for juveniles 7
when it enacted the Juvenile and Delinquency Prevention Act of 1974 8
(“JDPA”). See Pub. L. No. 93‐415, 88 Stat 1109 (1974). As relevant here, 9
the JDPA contains four sections, now codified at 18 U.S.C. §§ 5033– 10
5036. Those sections demonstrate Congress expresses a clear 11
preference for preserving the juvenile’s connection to his or her family 12
and the family’s continued involvement in the juvenile’s life during 13
the period of federal pretrial detention. 14
First, the JDPA requires federal authorities to immediately 15
notify a child’s parents when federal authorities arrest a juvenile. 18 16

-- 34 of 42 --

35
U.S.C. § 5033. Following a juvenile’s arrest, the “juvenile shall be 1
taken before a magistrate judge forthwith.” Id. At that hearing, if the 2
juvenile has not already been released, “the magistrate judge shall 3
release the juvenile to his parents, guardian, custodian, or other 4
responsible party” unless the judge determines that “the detention of 5
such juvenile is required to secure his timely appearance before the 6
appropriate court or to insure [sic] his safety or that of others.” Id. § 7
5034 (emphasis added). In the event the magistrate judge does order 8
the juvenile detained, then section 5035 mandates that “[w]henever 9
possible, detention shall be in a foster home or community based 10
facility located in or near [the juvenile’s] home community.” Id. § 11
5035. 12
The structure of the JDPA factors into our conclusion in two 13
significant ways. First, the JDPA expresses a strong preference for 14
continued parental involvement during detention. Congress seems to 15

-- 35 of 42 --

36
have desired continued parental care, even during detention, for a 1
juvenile charged with a federal crime. See id. §§ 50335035. 2
Second, as amici point out, under circumstances like those in 3
Khalid’s case, the government’s proposed interpretation of “physical 4
custody” would leave the question of whether a child derives United 5
States citizenship entirely to the pretrial detention decision of a 6
magistrate or state court judge. See Br. of Amici Curiae Ctr. for Family 7
Representation et al. 7. That approach to deciding a child’s “weighty 8
interest in citizenship” would make citizenship a status that is 9
“casually conferred,” at odds with Congress’s detailed scheme for 10
immigration and naturalization. Fedorenko v. United States, 449 U.S. 11
490, 520 n.3 (1981) (Blackmun, J., concurring in judgment); see also 12
Arizona v. United States, 567 U.S. 387, 395 (2012) (“Federal governance 13
of immigration and alien status is extensive and complex.”). 14
Moreover, the BIA’s approach would seem to make the question of 15
citizenship dependent on factors irrelevant to the child’s eligibility for 16

-- 36 of 42 --

37
citizenship. For example, the JDPA allows a magistrate judge to 1
consider whether a child might appear at his or her next court hearing 2
when ordering detention. 18 U.S.C. § 5034. Many state courts in this 3
Circuit similarly may consider whether a juvenile will appear at 4
future hearings when deciding whether to order a juvenile detained 5
until trial. See Conn. Gen. Stat. § 46b‐133(c); N.Y. Fam. Ct. Act 6
320.5(3)(a)(i). Relying on such factors to determine citizenship would 7
likely render the BIA’s interpretation irrational. See Judulang v. Holder, 8
565 U.S. 42, 55 (2011) (“[A]gency action must be based on non‐ 9
arbitrary, relevant factors.” (emphasis added) (internal quotation 10
marks omitted)). Those concerns lend further support to our 11
conclusion that Khalid’s father’s “physical custody” did not simply 12
end on Khalid’s arrest or the detention decision of a judge. 13
Finally, we note that we do not deal in this case with a juvenile 14
adjudicated guilty and imprisoned pursuant to a court‐ordered 15
sentence at the time the juvenile claims to have acquired citizenship. 16

-- 37 of 42 --

38
There may be reason in such situations to determine that a minor is 1
not in a naturalizing parent’s physical custody for purposes of 8 2
U.S.C. § 1431. See Romo‐Jimenez v. Lynch, 607 F. App’x 745, 74546 (9th 3
Cir. 2015) (mem.) (concluding that a petitioner whose parent 4
naturalized after that petitioner was adjudicated guilty of a state 5
crime and imprisoned was not a U.S. citizen, because a juvenile court 6
had committed the petitioner to the legal custody of the California 7
Youth Authority). We need not address those circumstances as they 8
were not present in this case. 9
Finally, we observe that the BIA’s interpretation would 10
produce unintended results. Although Khalid’s case arises under his 11
unique circumstances, the BIA’s decision would likely produce 12
unfortunate consequences for the citizenship of other LPR children 13
facing different situations. For example, a high school boarding 14
student away at school would not derive citizenship from her parent 15
who naturalized unless she returned home before turning eighteen. 16

-- 38 of 42 --

39
Similarly, a student on a semester trip abroad might be denied 1
citizenship under the BIA’s interpretation if his parent naturalized 2
while he was abroad and he turned eighteen while on that trip. The 3
BIA’s interpretation likely forecloses derivative citizenship under 4
those circumstances, without any inquiry into the particular 5
circumstances of the parent’s custody or the law governing the child’s 6
separation from the parent. We think that approach at odds with both 7
the statute’s language and context and decline to adopt it here. 9 8
CONCLUSION 9
We hold that the brief, temporary separation created by 10
Khalid’s pretrial juvenile detention did not prevent Khalid from 11
satisfying the “physical custody” requirement of 8 U.S.C. § 1431(a), 12
and that consequently, he obtained derivative citizenship from his 13
9 We find our conclusion regarding Khalid’s citizenship status sufficiently clear
from the text of the INA, the statutory context, and the JDPA to decline to address
Khalid’s arguments regarding due process and equal protection. We express no
view on those arguments.

40
father in 2011. As a result, Khalid is a citizen of the United States. 1
Accordingly, we GRANT the petition for review, VACATE the BIA’s 2
decision, and REMAND with instructions to terminate Khalid’s 3
removal proceedings 4

-- 40 of 42 --

JACOBS , Circuit Judge, with whom Judge Hall joins, concurring: 1
I concur in the Opinion of the Court, its reasoning, and its 2
result. At the same time, I cannot congratulate Khalid on his 3
American citizenship. He plotted sneaking violence against 4
Americans, who gave his family a home, and he cooperated with the 5
authorities only when, having been caught, he found himself 6
needing another kind of refuge. 7
Khalid derived citizenship from his citizen father. The 8
premise for that derivative citizenship was that, during the crucial 9
period between Khalid’s father’s naturalization and Khalid’s 10
eighteenth birthday, Khalid was in his fatherʹs physical custody‐‐ 11
notwithstanding that he was behind bars on terrorism charges, in 12
the custody of the authorities. So I need to emphasize, consistent 13
with the Opinion, that that result obtained only because the 14
detention was pretrial, brief, and in a juvenile facility where, under 15
federal law, Khalid’s citizen father was allowed and encouraged to 16

exercise influence over his son. The holding of this case is surprising 1
enough, and does not lend itself to expansion. 2
