10 years residence, three-tier approval, dual allowed — informational
Swiss naturalization is unique because the decision is made by three independent levels: federal (SEM), cantonal, and communal (Gemeinde). Dual citizenship has been allowed since 1992. This page is informational and does not replace consultation with a qualified immigration lawyer.

Swiss naturalization under the Citizenship Act (Bürgerrechtsgesetz, BüG / Loi sur la nationalité, LN, 2018) requires 10 years of lawful residence. The central uniqueness is the three-tier approval system: each of the three levels can refuse the application independently. Passing at federal level does not automatically mean a positive decision at cantonal or communal level.
Dual citizenship has been allowed since 1992 (art. 32 BüG does not require renunciation of the previous one), distinguishing Switzerland from Austria. Federal language minimums are B1 oral and A2 written (in one of the official languages: German, French or Italian); cantons may require more.
Federal character
The standard path requires 10 years of lawful residence in Switzerland, status C (permanent settlement permit), successful integration, and meeting federal and cantonal criteria.
At least 10 years of residence in Switzerland, of which 3 years in the last 5. Years between the 8th and 18th birthday count double (art. 9 BüG). Status at the time of application: C-permit (Niederlassungsbewilligung).
Federal minimum: B1 oral and A2 written in one of the official languages (German, French or Italian) — art. 6 BüV. Cantons may require more (e.g. B1 written, B2 oral). Certificate: fide, Goethe, telc, ÖSD, DELF, CILS, etc.
Employment or self-employment, regular tax and contribution payments, no active receipt of social welfare in the last 3 years, participation in community life (art. 12 BüG).
Criminal record extract (federal and cantonal) without serious convictions. Minor expunged offences are usually tolerated, but any conviction can trigger a closer review.
Test on knowledge of Switzerland, the canton, and the commune — history, geography, constitutional structure, human rights. Format and content vary by canton. Usually written or combined.
Written declaration of respect for the Federal Constitution and Swiss legal order. Security check by SEM (federal agency) — part of the federal decision (art. 11 BüG).
The essence of the Swiss system is that the decision is made by three independent levels. All three must give a positive answer for naturalization to take effect. Each level can refuse independently.
Check of federal conditions: 10 years of residence, status C, general security check. Federal consent precedes the cantonal procedure.
SEM — State Secretariat for Migration
Check of cantonal conditions: minimum residence within the canton (2–5 years), language, integration, civics test. The canton makes its own decision.
Cantonal citizenship office
Check of local integration, participation in community life, language in everyday contact. In some cantons the case goes to a vote of the communal assembly.
Gemeinde / commune / comune
Each level can refuse independently
Under art. 9 BüG, years spent in Switzerland between the 8th and 18th birthday count double for meeting the 10-year residence requirement. This provision encourages naturalization of the second generation and of those who spent their school or adolescent period in Switzerland.
Proof of residence as a child
The spouse of a Swiss citizen can qualify for simplified federal naturalization (Erleichterte Einbürgerung) under art. 21 BüG. In that case the federal agency SEM runs the procedure without cantonal and communal decisions.
Children born abroad to a Swiss parent
While 10 years is the federal minimum, cantons set additional criteria: minimum residence within the canton (often 2–5 years), language, civics test, and the communal procedure. Below is an indicative overview of 8 most populous cantons.
| Canton | Main features of the procedure |
|---|---|
| Zurich (ZH) | 2 years residence in canton, online civics test, procedure usually 18–24 months |
| Bern (BE) | 2 years in canton, cantonal civics test, communal procedure may include interview |
| Geneva (GE) | French language (B1 oral / A2 written federal min.), 2 years in canton |
| Vaud (VD) | French language, 3 years in canton, civics test for canton and commune |
| Ticino (TI) | Italian language (federal minimum), 5 years in canton |
| St. Gallen (SG) | German, 5 years in canton, cantonal civics test |
| Aargau (AG) | German, 3 years in canton, civics test (federal and cantonal parts) |
| Basel-Stadt (BS) | German, 2 years in canton, integration interview and civics test |
Note: rules change. Before planning, check the official sources of your canton or consult a lawyer.
In some Swiss cantons, a naturalization application must be approved by the local community — not only by the commune administration. This usually happens at a session of the communal assembly or a residents assembly (Gemeindeversammlung).
Practice varies: in some communes it is just a formal confirmation, in others a serious assessment in which candidates are invited to introduce themselves. The procedure can take longer or shorter depending on the schedule of communal meetings.
Political dimension
The procedure may vary by canton and commune. The following is an indicative sequence of steps.
Verify that you meet federal and cantonal conditions (10 years, status C, language, integration). Many cantons offer checklists and pre-application consultations.
The application is normally submitted to the commune of residence. The commune is the first instance to verify local conditions.
Passed civics test (cantonal) and language certificate (B1 oral / A2 written federal minimum, cantons may require more). In some cantons the civics test is part of the interview.
Upon a positive communal assessment, the file is forwarded to the cantonal citizenship office. The canton checks its own conditions (residence in the canton, civics test).
Upon positive cantonal decision, the file goes to SEM (federal agency). SEM checks the federal conditions and security. With a positive decision, the federal stage closes.
Upon positive decisions on all three levels, the applicant becomes a Swiss citizen. Registration is done in the civil register of the commune and canton; the applicant receives the corresponding documents.
