Question juridique clé
Whether the family reunification request for Y. was timely under the transitional rules and Art. 47 AuG after the father's later naturalization.
Solution extraite
The request was late; the reunification period had already expired and did not restart upon the father's naturalization.
Motifs extraits
The transitional regime required already possible reunification requests to be made within the applicable period under the new law; a later status change does not create a new time limit once the earlier one has lapsed.
