Being no longer subject to the compulsory OASI/DI/EO, Swiss nationals and EU or EFTA citizens who leave Switzerland, can, under certain conditions, join the voluntary OASI/DI.
- To have Swiss nationality, or that of a European Union (EU) or European Free Trade Association (EFTA) member state;
- To reside outside the EU or EFTA;
- To have been insured under the compulsory OASI/DI/EO scheme for at least five consecutive years;
- To submit the membership application form within 12 months after leaving the compulsory OASI/DI/EO.
Membership is granted on an individual basis. Each member of the family must submit a separate application form.
If you are under 18 or have been exempt from paying contributions towards the compulsory OASI/DI/EO scheme, years of residence in Switzerland count as years of insurance.
