Swiss Citizenship Language Requirement: B1 Spoken, A2 Written — and the Rest of the Rules
By Language Lab editorial team
Swiss naturalisation needs B1 spoken and A2 written skills in a national language, 10 years' residence and a C permit. What SEM says and how to prepare.
To naturalise in Switzerland at federal level you must show oral skills of at least B1 and written skills of at least A2 in a national language — German, French, Italian or Romansh (Article 6 of the Citizenship Ordinance). You also need ten years of residence and a C permit (permanent residence); years between ages 8 and 18 count double, with at least six years actually lived there. Cantons add their own residence rules of two to five years in the canton and commune, and can set extra integration requirements.
The federal language rule
Article 6 of the Swiss Citizenship Ordinance (Bürgerrechtsverordnung, BüV) requires applicants to prove oral language skills of at least B1 and written skills of at least A2 of the Common European Framework in one of Switzerland's national languages. The State Secretariat for Migration (SEM) recognises certificates on its list of accepted language certificates for A2 written and B1 oral. The fide test is one of the language assessments designed for this purpose. Cantons can require higher levels.
| Requirement | Federal rule |
|---|---|
| Spoken language | At least B1 in a national language |
| Written language | At least A2 in a national language |
| Residence | 10 years; ages 8–18 count double (at least 6 years actually lived) |
| Permit | C permit (permanent residence) |
| Cantonal residence | 2–5 years in the canton and commune, set by cantonal law |
| SEM fee (adult) | CHF 100, plus cantonal and communal fees |
Which language?
Any national language counts at federal level. Because cantons and communes run the procedure and assess your integration where you live, check with your canton which language it expects — for most people it's the local language, such as French in Geneva or German in Zurich.
Residence and the permit
According to SEM, foreign nationals who have lived in Switzerland for ten years and hold a C permit can apply for ordinary naturalisation to their commune or canton. Time on a B or C permit counts, time on an F permit counts half, and time in the asylum procedure (N permit) or on a short-stay L permit doesn't count. The canton checks formal requirements and integration, then SEM issues a federal naturalisation licence before the cantonal decision.
What B1 spoken and A2 written mean
B1 speaking means you can handle most everyday conversations, describe your experiences and plans, and give short reasons for your opinions. A2 writing means you can write short, simple notes and messages about everyday matters — a note to a neighbour, a simple message to a school. The spoken bar is the harder one, so most of your preparation should be speaking practice.
How to prepare
- Choose the national language of your canton and commune.
- Prioritise speaking: B1 oral is the higher bar.
- Check your canton's own rules — some ask for more than the federal minimum.
- Book an SEM-recognised test, such as the fide test, well ahead of your application.
- Practise real conversations: Language Lab teaches German, French and Italian with a voice tutor for everyday situations.
What B1 speaking looks like in practice
| Situation | Example (German) | Example (French) |
|---|---|---|
| Introducing yourself | Ich wohne seit acht Jahren in Luzern und arbeite als Pflegefachfrau. | J'habite à Lausanne depuis huit ans et je travaille comme infirmière. |
| Explaining a problem | Mein Zug hatte Verspätung, deshalb komme ich zehn Minuten zu spät. | Mon train avait du retard, c'est pourquoi j'arrive dix minutes en retard. |
| Giving an opinion | Ich finde, dass man mehr Velowege bauen sollte, weil es sicherer ist. | Je pense qu'on devrait construire plus de pistes cyclables, parce que c'est plus sûr. |
At B1 you speak in connected sentences, give reasons, and handle follow-up questions about your daily life, work and community. For A2 writing, the task is simpler: short, clear notes and messages — to a neighbour, a school or an employer.
Integration is assessed locally
Language is one part of integration. Cantons and communes also assess whether you're familiar with the Swiss way of life, and some ask about local geography, history and institutions. Because the procedure is cantonal, read your canton's own guidance early and plan both language and local knowledge together.
A preparation checklist
- Confirm which national language your canton expects and whether it asks for more than B1/A2.
- Check SEM's list of recognised language certificates before booking any test.
- Practise speaking about your daily life, work, family and plans in connected sentences.
- Write short notes and emails weekly and get them corrected.
- Learn about your commune and canton — the naturalisation report looks at local integration.
