Language Integration Requirements for Swiss Citizenship

Becoming a Swiss citizen is a multifaceted process that requires applicants to demonstrate proficiency in the language spoken in the canton where they reside. There are twenty-six semi-autonomous cantons in Switzerland, which speak German, French, Italian, and/or Romansh. 

Each canton has its own language proficiency requirements that need to be met as part of its citizenship requirements. For example, someone who lives in Zurich may need to take the A1 exam for German.

Typically, applicants for citizenship are required to have a minimum of a B1 level for spoken language and an A2 level for written language proficiency certification. The levels are defined by the Common European Framework of Reference for Languages (CEFR). Some cantons may have stricter language requirements, so you should check with the local migration agency to find out what is required.

Language proficiency is a requirement for Swiss citizenship regardless of the application process being pursued (e.g., naturalization, marriage to a Swiss citizen, investment, etc.). Citizenship applications are usually made to the local canton, which then forwards them to the State Secretariat for Migration (SEM) for review and approval. SEM is the national agency responsible for issuing visas, residency permits, and work permits to foreigners.

What Is CEFR?

CEFR is an internationally recognized standard created by the Council of Europe used to teach, learn, and evaluate an individual’s level of language proficiency. It is widely used by educational institutions, employers, and language training providers to assess an individual’s ability to understand, speak, read, and write a language.

There are six CEFR levels from A1 to C2. A1 and A2 levels are for those who can understand and use simple phrases. B1 and B2 represent someone who can understand the main points of a conversation on familiar topics that occur at work, school, or in the community. C1 and C2 levels are for those who can comprehend a wide range of demanding content, including longer texts, nuances, and implied meanings.

Why Language Is a Citizenship Requirement

Switzerland is renowned for its high quality of life, making it a highly desirable place to reside. Ensuring that those who want to become citizens can communicate in at least one of the native languages spoken in the country helps preserve Swiss culture and values. 

As part of the citizenship process, the applicant may also be asked to demonstrate a basic knowledge of Swiss history, politics, and customs. Familiarity with Swiss life and language reflects a person’s interest and willingness to integrate into Swiss culture when living and working in the country.

How to Prove Language Proficiency

First, check with the local canton for their specific language requirements. SEM also publishes a list of language certifications and the conditions under which it will accept them. The conditions vary depending on the type of permit being requested, length of residency, and the applicant’s nationality.
