Kernrechtsfrage
Whether the deceased husband had established Swiss domicile or insured status sufficient to trigger a widow’s pension under AHVG.
Extrahierter Entscheid
The husband had not established Swiss domicile in the relevant sense; his stay remained unauthorized or only short-term and did not create insurance coverage.
Extrahierte Begründung
A person subject to an entry ban does not acquire domicile merely by physical presence and intent to live there. A short stay for medical treatment is treated as a non-insured short-term stay under the AHVV.
