Kernrechtsfrage
Whether the residence permit could be refused because the applicant had concealed essential facts and had been sentenced to long-term imprisonment abroad.
Extrahierter Entscheid
Yes. The applicant had knowingly withheld decisive foreign convictions and had been sentenced to long-term prison terms, so the statutory grounds for revocation/expiry were met.
Extrahierte Begründung
Foreign convictions are relevant under the Aliens Act if they satisfy Swiss-law criminality and fair-trial requirements. The applicant had a duty of full disclosure and intentionally misled the authorities by denying prior convictions.
