Kernrechtsfrage
Whether the appeal against refusal to renew the residence permit is admissible despite no federal entitlement to the permit.
Extrahierter Entscheid
No federal-law or treaty-based entitlement to renewal existed, so administrative-law appeal was excluded and the filing could not be entered into.
Extrahierte Begründung
Renewal of a residence permit is discretionary unless the applicant can rely on a specific federal norm or treaty right. The applicant no longer depended on his parents, did not derive a claim from family life under Art. 8 ECHR, and showed no protected private-life interest meeting the case-law threshold.
