🇫🇮 Finland · Citizenship

Naturalization rules: required residence years, language and civics requirements, and each country's dual-citizenship policy.

Quick answer

Finland grants citizenship after about 5 years of continuous residence (or a longer aggregate period), passing a Finnish or Swedish language test, having a secure livelihood and a clean record. Finland permits dual citizenship. Applications go to the Finnish Immigration Service (Migri).

Finnish citizenship by application is handled by Migri and generally depends on identity, residence period, language skills, integrity and payment-obligation conditions. Finland allows multiple citizenship, but the other country’s law can still affect nationality status.

  • Finland permits multiple citizenship; applicants should also check their original country’s law.
  • Residence-period rules differ by status and can change; use Migri’s current guide.
  • Citizenship is a legal-status decision; this page is general information, not case advice.
