As with facilitated naturalisation, renaturalisation is in the responsibility of the Confederation; cantons and communities have a right of appeal. The general requirement for renaturalisation is close connections with Switzerland. Renaturalisation can be obtained by people who have lost Swiss nationality (by forfeiture, marriage or release from Swiss nationality).

Applicants areparticularly foreign spouses of Swiss nationals and foreign children, one of whose parents is Swiss
