Kernrechtsfrage
Whether the appellant had an enforceable residence-permit claim under Article 8 ECHR based on family life with her sister.
Extrahierter Entscheid
No protected family-life claim existed because she was financially independent, had her own home and work, and was not dependent on her sister.
Extrahierte Begründung
For non-core family members, Article 8 ECHR requires a dependency relationship. The findings showed only a normal sibling relationship, not the necessary dependence.
