All persons residing or working in Switzerland are compulsorily insured under DI. To receive DI benefits, you must fulfil several conditions.
Nationals of an EU or EFTA Member State have the same rights as Swiss citizens. If you come from another country, benefits may be limited once you return to your country of origin if it has not concluded a social security agreement with Switzerland.
Swiss citizens and nationals of EU or EFTA countries residing in a country outside of this zone have the option, under certain conditions, of joining the voluntary DI scheme.
