To acquire Finnish citizenship, you should have at least a satisfactory level of proficiency in spoken and written Finnish or Swedish. The best way to demonstrate this is to acquire a National Certificate of Language Certificate (YKI): minimum level three (intermediate). The Finnish Immigration Service is responsible for citizenship applications.

According to the guidelines of the Finnish Immigration Service, their definition of ”satisfactory level of proficiency in spoken and written Finnish or Swedish” in practice means the completion of two components of the test at least at the skills level three. To meet the requirement for satisfactory level of spoken and written language skills, only the following combinations of test components are accepted:

  • speaking and writing


  • listening comprehension and writing


  • reading comprehension and speaking.

Please note that you will only acquire the certificate when you take the whole test, including all the four components. The whole test will be taken during the same day. However, you can demonstrate the required component combinations for the citizenship application by combining several certificates (Certificates received from 1 January 2012 onwards).

To acquire Finnish citizenship, you need to complete the national language proficiency test in Finnish or Swedish at intermediate level (skill levels 3 to 4). For information about registration, see Register for a national language proficiency test.
