Swiss Citizenship and Naturalization

Who can apply: residence and permit requirements

Ordinary naturalization requires a total of ten years of residence in Switzerland. Years lived in the country between the ages of 8 and 18 count double, which shortens the path for people who arrived as children or teenagers. You must also have lived in the canton and municipality where you submit your application for a minimum period set by that canton, in addition to the federal ten-year total.

A C permit, the Swiss settlement permit, is a precondition for ordinary naturalization. If you currently hold a B permit (residence permit), you generally need to obtain your C permit first before you can submit a naturalization application. EU/EFTA nationals typically qualify for a C permit after five years of continuous residence, while most other nationalities reach it after ten years, subject to the applicable bilateral agreements and individual circumstances.

Ordinary versus facilitated naturalization

Which route applies to you depends on your personal and family situation rather than on preference. Ordinary naturalization is the default route for any long-term foreign resident. Facilitated naturalization applies only to specific situations defined by law, mainly spouses of Swiss citizens and certain descendants of long-established immigrant families (the so-called third generation).

Language level and integration criteria

For ordinary naturalization, you must demonstrate spoken and written command of the official language of your place of residence, at a minimum level of B1 (spoken) and A2 (written) on the Common European Framework of Reference. Accepted certificates vary by canton and can include fide, telc, Goethe-Institut, DELF or CELI qualifications, among others; check the accepted list for your specific canton and municipality before booking a test.

Beyond language, integration is assessed against several criteria: respect for public order and the rule of law, participation in economic life through stable employment or a valid reason for its absence, willingness to pursue further training, and a basic familiarity with the geography, history and political system of Switzerland and of your canton. Some cantons and municipalities require an interview or a written civic knowledge test as part of this assessment.

Documents you will typically need

• •Completed application form for the canton and municipality of residence
• •Valid identity document and current residence permit (C permit for ordinary naturalization)
• •Extract from the Swiss criminal record and, where required, from your country of origin
• •Confirmation of registration from the residents' registration office
• •Certificate confirming no outstanding debt-enforcement proceedings
• •Language certificate meeting the required level for your canton
• •Evidence of stable income or financial situation
• •School or training records for any children included in the application
• •Evidence of integration, such as local involvement, volunteering or community ties

Costs and typical timelines

Naturalization involves fees at the federal, cantonal and municipal level, and the total varies significantly depending on where you apply: some cantons and municipalities charge considerably more than others, and family applications are usually priced differently from single applications. Ask your municipality and canton directly for their current fee schedule before you apply, since these amounts are set locally and are revised from time to time.

For ordinary naturalization, the combined federal, cantonal and municipal review typically takes around one to three years from a complete application to a final decision, depending on the canton, the municipality and how quickly your file is processed at each stage. Facilitated naturalization generally moves faster, since it involves only the federal authority, but exact timelines depend on your individual file.

Dual nationality and children

Switzerland has allowed dual and multiple nationality since 1992, so becoming Swiss does not automatically require you to give up your current nationality. Whether you can keep it depends on the law of your country of origin, not on Swiss law, so check your home country's rules before assuming you can hold both passports.

Switzerland does not grant citizenship automatically to children born on Swiss soil to foreign parents; a child generally acquires the nationality of their parents at birth. Third-generation descendants of long-established immigrant families may qualify for a facilitated naturalization procedure under conditions tied to their parents' and grandparents' residence and integration in Switzerland, provided they apply before a fixed age limit set by law.
