Citizenship

Citizenship for a child

A child is a Finnish citizen if, at the time when the child was born

  • the mother was a Finnish citizen 

  • the father was a Finnish citizen, the mother was a foreign national and the parents were married

A child born outside marriage

If a child was born outside marriage and only the father was a Finnish citizen when the child was born, a declaration of acknowledgement of paternity is required. An application to obtain a Finnish citizenship for the child can be filed after that by means of declaration.

Please remember to register the birth of a Finnish citizen at the Local Register OfficeLink to another website.(Opens New Window)

Citizenship on application or declaration

The Finnish Immigration Service can grant Finnish citizenship on declaration or on application. If you reside abroad, you can submit a citizenship application for a child or adopted child, a declaration on recovery of citizenship, or an application for release from citizenship at a Finnish mission or honorary consulate.

The declaration or application must always be submitted in person. The Finnish Immigration Service can start processing the matter only after you have paid the processing fee.

Multiple nationality

If you have multiple nationality, you must find out yourself what rights and obligations you have in your other home country. Missions of Finland abroad can serve only in matters concerning Finnish citizenship.

If you have multiple nationality and you are staying in your other home country, you are treated in accordance with the local laws in the same way as persons who are citizens of that country. In such situations, the Ministry for Foreign Affairs of Finland normally has rather limited opportunities to provide consular assistance.
