Overview — Three routes
The Federal Act on Swiss Citizenship (SCA, SR 141.0, in force since 1 January 2018) provides for three main routes to Swiss citizenship:
Ordinary naturalisation (Art. 9-15 SCA) — the standard procedure for persons who have been residing in Switzerland for a longer period.
Facilitated naturalisation (Art. 21-22 SCA) — accelerated procedure for certain groups of people, in particular spouses of Swiss citizens.
Re-naturalisation (Art. 24-25 SCA) — Return of former Swiss citizens to citizenship.
Swiss citizenship has three levels: municipal, cantonal and federal citizenship. When a person acquires Swiss citizenship, they simultaneously acquire citizenship of a canton and a municipality – typically the canton and municipality of their place of residence at the time of naturalisation.
Route 1 — Ordinary Naturalisation (Art. 9-15 SCA)
Formal requirements (Art. 9 SCA)
Length of stay: at least 10 years of residence in Switzerland. The period between the ages of 8 and 18 counts double – for a person who has grown up in Switzerland, the actual length of stay may therefore be shorter.
C settlement permit: required at the time of application.
Familiarity with Swiss living conditions (Art. 11 SCA, as specified in SCA Ordinance Art. 2-4).
Material requirements (Art. 11 SCA)
Naturalisation requires successful integration, which federal law divides into five criteria:
Respect for Swiss law — no significant criminal record entries, no outstanding enforcement orders or bankruptcy proceedings. Reference is made to cantonal and municipal practice (see below regarding the Aargau judgment).
Respect for the values of the Federal Constitution — commitment to the rule of law, democratic principles and human rights.
Language skills: spoken level B1, written level A2, in an official language of the place of residence (DE / FR / IT / RG). Proof must be provided by means of a language certificate recognised by the SEM (fide, telc, Goethe, DELF, CILS, etc.). Persons who have attended school for a sufficient period in an official language are exempt.
Participation in economic life or acquisition of education — gainful employment, self-employment, receipt of pension, education or training, care of children or dependent relatives.
Promotion of family integration — if the applicant has a family, the integration of the spouse and children will also be taken into account.
Grounds for refusal (Art. 11 para. 2 SCA)
Naturalisation may be refused if the person poses a threat to the internal or external security of Switzerland or does not adequately respect the values of the Federal Constitution.
Requirement for habitual residence
In addition to the federal jurisdiction, the canton and municipality have their own independent requirements regarding habitual residence (Art. 12 SCA in conjunction with cantonal legislation):
Cantonal residence: typically 2-5 years, varying by canton.
Local residence: typically 3 years, varying by municipality.
See the cantonal/ca_*.md files for an overview of the cantonal requirements.
Procedure
Application to the canton — written application with the inclusion of supporting documents (criminal record extract, debt collection register extract, language certificate, payslips or proof of self-employment, tax assessments, rental agreement, school certificates for children, biographical curriculum vitae).
Cantonal examination — The migration service and the citizenship office examine the formal and substantive requirements. Submission of the file to the federal authorities.
Federal naturalisation permit issued by the SEM — the State Secretariat for Migration examines whether the federal legal requirements have been met and issues the federal naturalisation permit. This process typically takes 6-12 months.
Cantonal naturalisation procedure — the canton conducts its own procedure, in many cantons with one or more of the following elements: written test on Swiss affairs, personal interview (naturalisation interview), hearing before a naturalisation commission.
Municipal naturalisation procedure — the municipality of residence conducts its own procedure, which varies depending on the municipality (ranging from a simple confirmation decision to a vote at a public meeting).
Formalisation — upon acceptance, the naturalisation is formalised; Swiss citizenship is acquired when the decision becomes final.
Procedure and Costs
Total duration (from application to registration): typically 18-36 months. In complex cases and in cantons with a separate assembly procedure, it may take longer.
Total costs (federal government + canton + municipality): in practice, CHF 1,500 to CHF 5,000, depending on the canton and municipality. Some municipalities in French-speaking Switzerland and Ticino are lower; some municipalities in German-speaking Switzerland are higher.
Legal protection in the event of rejection
Intra-cantonal appeal to the cantonal appeal authority within the cantonal appeal period (typically 30 days).
An appeal to the Federal Supreme Court against cantonal final decisions is permitted only in limited cases (Art. 83 Federal Act on Administrative Procedure; decisions on citizenship are subject to a restriction on admissibility).
The facilitated naturalisation is a federal procedure that does not involve a municipal assembly. It is open to:
Spouses of Swiss citizens (Art. 21 SCA)
Requirements:
Marital relationship with a Swiss national for at least 3 years.
Residence in Switzerland for at least 5 years, including the year prior to the application.
OR (for spouses residing abroad): at least 6 years of marital cohabitation, close ties to Switzerland.
Integration: comparable criteria to those for ordinary naturalisation, although the language requirement is generally set at a slightly lower level (oral level A2 is sufficient in many cases).
No threat to internal or external security.
Facilitated naturalisation is comprehensively regulated by federal law. The application is submitted to the SEM. The processing time typically takes 12-24 months. The costs are lower than for ordinary naturalisation (typically CHF 500 to CHF 1,000).
Children with a Swiss parent (Art. 22 SCA)
Children born abroad who have a Swiss parent can apply for naturalisation under simplified conditions. Registration with the Swiss consulate is typically possible before the age of 22.
Stateless persons and persons who have grown up in Switzerland
Special provisions apply to stateless persons (Art. 23 SCA) and to third-generation foreigners (Art. 24a SCA, in force since 15.02.2018). The latter can apply for facilitated naturalisation if three generations of their family have lived in Switzerland, and they themselves were born in Switzerland and completed their compulsory schooling here.
Route 3 — Re-naturalisation (Art. 24-25 SCA)
Individuals who have lost Swiss citizenship through marriage to a foreign national, by waiver or by loss of citizenship (Art. 38 SCA) may apply for re-naturalisation. The requirements are: close ties to Switzerland, and, where applicable, residence in Switzerland for at least 3 years in the case of re-naturalisation within Switzerland.
Special Circumstances
The Aargau Judgment of 2024 — Enforcement proceedings as an obstacle
In 2024, the Federal Supreme Court ruled in an Aargau case that a blanket refusal of naturalisation based solely on existing debt collection proceedings may violate fundamental constitutional rights if the debt collection proceedings are relatively minor and do not indicate a significant breach of economic self-responsibility. This has led to a change in cantonal practice; some cantons have adjusted their administrative practice, while others continue to apply a strict approach. In each individual case, a case-specific assessment by a lawyer is required.
Receipt of social welfare benefits
Receipt of social welfare benefits in the years immediately preceding the application is considered by many cantons to be a reason for refusal. Cantonal practice varies: in some cantons, it is sufficient if no social welfare benefits have been received in the last 3 years; other cantons require 5 years.
Dual nationality
Switzerland permits dual nationality (Art. 1 para. 2 SCA in conjunction with Art. 28 SCA without the requirement of renunciation). However, whether the second nationality is retained depends on the law of the other state. Some states (e.g. India, China) do not recognise dual nationality and require renunciation. Advice from the consulate of the second nationality is required.
Naturalisation interview and assembly
In many municipalities, a naturalisation interview takes place, during which the applicant is questioned about Swiss conditions, values and customs. In some German-speaking Swiss municipalities, a naturalisation assembly or a vote is also held.
In several judgments, the Federal Supreme Court has held that naturalisation decisions must be justified and are subject to the prohibition of discrimination (BGE 129 I 232 ff., BGE 132 I 167 ff.). A refusal solely on the grounds of origin or religion is unconstitutional.
What SIP does not cover (Anti-Scope)
No assessment of the individual prospects of success («You will be naturalised»).
No strategic advice for the naturalisation interview or for preparing for a municipal assembly.
No assessment as to whether specific enforcement proceedings, criminal cases or receipt of social welfare benefits in individual cases would be an obstacle to naturalisation.
No assistance during the proceedings — representation before authorities and in court requires a lawyer registered in the cantonal bar register.
Preparation — What needs to be clarified before submitting the application
Calculation of the length of residence using the cantonal requirements profile (see cantonal file).
Obtain a language certificate (B1 oral, A2 written for ordinary naturalisation; potentially lower requirements for facilitated naturalisation).
Criminal record extract (current – no older than 3 months).
Extract from the debt collection register (current – no older than 3 months) – if there are any debt collection entries: obtain a legal assessment.
Tax assessments for the last few years — proof of participation in gainful activity.
Detailed Curriculum Vitae — Document stay in Switzerland with supporting evidence (rental agreements, payslips, school certificates).
Family structure — if the family is naturalised together, provide evidence for spouses and children.
If you are unsure about your prospects: seek legal advice via the SIP referral list – there is no risk of submitting an application without an initial assessment.

Awaiting review and approval by the supervising lawyer of record, as well as by cantonal practice specialists (ZH, BE, GE, VD, BS minimum) in accordance with ADR-016. The Aargau judgment of 2024 concerning enforcement as a ground for refusal must be compared with the current state of cantonal administrative practice before publication — this practice is currently undergoing changes.
