Subject to the sovereignty of the receiving state, Swiss national law also applies to Swiss nationals abroad, insofar as it governs relations between these individuals and their home country. Rights and obligations that also apply abroad pertain, for example, to the following areas:
- Acquisition or loss of Swiss citizenship
- Compulsory national service (i.e. military service or alternative civilian service)
- The exercise of political rights by Swiss nationals living abroad
- Civil status (duty to declare)
- Elements of social insurance as well as social welfare
Article 40 of the Federal Constitution charges the Confederation with promoting relations with and among Swiss nationals living abroad. Fulfilment of this constitutional mandate is principally enshrined in the Federal Act on Swiss Nationals and Institutions Abroad (Swiss Abroad Act).
