Requirements, process, timelines, cantons — everything you need to know before submitting your application.
Who can apply for naturalization?
Ordinary naturalization is open to any foreign national legally residing in Switzerland who meets the federal, cantonal and municipal requirements.
10 years of residence
You must have lived in Switzerland for at least 10 years. Years spent between ages 8 and 18 count double (up to 5 additional years).
Successful integration
Respect the Swiss legal system, participate in social and economic life, and not pose a threat to internal or external security.
National language proficiency
Minimum level B1 oral and A2 written in one of the four national languages (German, French, Italian or Romansh).
Sound financial situation
Not dependent on social welfare (or having repaid it) and no tax debts to the state.
What documents do you need?
Each municipality may require specific documents. Here is the list of documents generally required for ordinary naturalization.
Identity
- Valid passport or identity card
- Birth certificate (translated and apostilled if necessary)
- Marriage or civil partnership certificate (if applicable)
- Birth certificates of minor children
Residence

Integration
- Language level certificate (minimum B1 oral, A2 written)
- Civic knowledge test results
- Evidence of social participation (associations, volunteering…)
Finances
- Certificate of non-dependence on social welfare
- Certificate of no tax debt

This list is indicative. Contact your municipality of residence for the full list of required documents.
How does the procedure work?
Naturalization involves three levels: the Confederation, the canton and the municipality. Each level may add its own requirements.
Municipal application
You submit your dossier to your municipality of residence. It assesses your local integration and provides a recommendation.
Cantonal authorization
The canton reviews your dossier and verifies cantonal requirements. It grants or refuses authorization.
Federal authorization
For non-EU/EFTA nationals, the State Secretariat for Migration (SEM) must also approve the application.
Naturalization ceremony
Once all authorizations are obtained, you sign the declaration of honour and receive Swiss citizenship.
Municipal, cantonal, federal
Ordinary naturalization is a three-tier procedure. Each level reviews your application according to its own criteria and may add conditions.
The municipality
First level — local integration
Your municipality of residence is the first to process your application. It assesses your local integration: neighbourhood participation, knowledge of the local area, personal interviews or hearings before a committee. It issues an opinion (favourable or unfavourable) that carries significant weight in the rest of the process.
The canton
Second level — cantonal requirements
The canton reviews your file against its own requirements: length of residence in the canton, language level, civic knowledge test. Some cantons require an interview or cantonal committee hearing. The canton grants or refuses cantonal naturalization authorization — without it, the procedure stops.
The Confederation
Third level — non-EU/EFTA nationals
For nationals of non-EU/EFTA countries, the State Secretariat for Migration (SEM) must also approve the application. It checks for serious criminal convictions, absence of internal security threats, and compliance with federal residence requirements. This step can add 6 to 18 months to the process.
Alternative paths and special situations
Depending on your personal situation, simplified procedures or specific rules may apply.
Facilitated naturalization
- 3 years of marriage to a Swiss citizen
- 5 years of total residence in Switzerland
- Successful integration and clean criminal record
Facilitated naturalization is handled directly at federal level, bypassing the cantonal and municipal stages. Average processing time: 1 to 2 years.
Minor children
Children born to Swiss parents automatically receive Swiss nationality at birth. Minor children can be included in a parent's ordinary naturalization application. Once they turn 18, they must file their own application.
Dual nationality
Switzerland has allowed dual or even triple nationality since 1992. You are therefore not required to give up your original nationality. However, check whether your country of origin also allows dual nationality — some states require a formal renunciation.
How long and how much?
depending on the canton and municipality. Some municipalities process applications faster than others.
Fees vary significantly by canton and municipality. Check with your local administration.
Most cantons require a civic knowledge test. Prepare with our quiz.
Each canton has its own rules
While federal requirements apply everywhere, each canton and municipality adds its own conditions. Here are the key differences to know.
The civic knowledge test
Most cantons (ZH, BE, VD, GE, VS, FR…) require a test on Swiss institutions, history and geography. The format, minimum score and test language vary by canton.
Processing times
Processing times range from 6 months (efficient municipalities, complete files) to over 3 years (major cities, complex cases). Central Swiss cantons are generally faster than French-speaking or Zurich cantons.
Total cost
Municipal and cantonal fees vary enormously: from CHF 200 in some small municipalities to over CHF 3,000 in cities like Geneva or Zurich. The federal fee is fixed at CHF 100.
Cantonal residence requirements
Beyond the federal 10-year requirement, each canton requires a period of residence within its territory: generally 2 to 5 years. Some municipalities add a local residence condition of 1 to 3 years.
Rules change regularly. Always check the official website of your canton or municipality before submitting your application.
Frequently asked questions
Can I keep my original nationality?
Yes. Switzerland has allowed dual or even triple nationality since 1992. Check whether your country of origin also permits this.
Does my Swiss spouse make naturalization easier?
Yes. Facilitated naturalization applies after 3 years of marriage to a Swiss citizen and 5 years of residence in Switzerland.
Do my children automatically become Swiss?
Children born to Swiss parents automatically receive citizenship. Minor children can be included in an ordinary naturalization application.
What happens if my application is rejected?
You can appeal to the competent cantonal authority. A refusal must be justified and you have a legal deadline to contest it.
Is the knowledge test difficult?
It covers Swiss institutions, history, geography and civic life. Our quiz covers exactly these topics across all 26 cantons.
Can I apply with a B permit?
Generally no. Ordinary naturalization usually requires a C permit (establishment permit). A few cantons accept a B permit under strict conditions. Check your canton's rules.
I received social welfare. Am I blocked?
Not necessarily. If you have fully repaid the amounts received, the condition is considered met. If you are still receiving welfare at the time of application, it will generally be refused.
Can I take the test in the language of my choice?
No. The test must be taken in the official language of the canton where you live. If you live in a German-speaking canton, the test is in German. Some bilingual cantons (Fribourg, Valais) offer a choice.
