Dual and multiple citizenship

Finnish nationals will no longer lose their Finnish nationality when they assume another nationality as Finnish legislation has accepted multiple/dual nationality since June 1st 2003. Finnish citizenship is decreed by constitution and more detailed in Finland’s new Nationality Act, which took effect in 1st September 2011.

If a Finnish national has acquired a foreign citizenship by naturalization prior to June 1st 2003, the person has probably lost his Finnish citizenship. Former Finnish citizens and their minor children may re-apply for Finnish citizenship by declaration subject to a charge.

It is recommended to find out a national law of a foreign state to avoid relinquish a current foreign citizenship unintentionally. 

The citizenship issues are under competence of the  Finnish Immigration Service.
