1. Check eligibility

As a rule, applicants need a C permit and ten years of residence in Switzerland. Years lived in Switzerland between ages 8 and 18 count double, with at least six years of actual residence. Cantons and communes may add residence periods and integration requirements.

2. Prepare and file the application

The cantonal or communal authority supplies the form and document list. The review commonly covers residence, language, taxes, debt enforcement, social assistance, criminal record and participation in employment or education.

3. Demonstrate integration

The authority checks language ability, respect for constitutional values and familiarity with life in Switzerland. A written test, interview or both may assess knowledge of history, geography, politics and society.

4. Cantonal and federal decisions

After positive communal and cantonal checks, the State Secretariat for Migration examines the federal conditions and issues federal authorisation. The canton then makes the final decision under its law.
