Declaration of citizenship - Ministry for Foreign Affairs
Declaration of citizenship
If you live abroad, you can submit a citizenship declaration or apply to be released from citizenship at any local police authority in Finland independent of your municipality of residence. If you are staying abroad, the document can be submitted at a mission or honorary mission of Finland.
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.
You can find more detailed information about citizenship matters, legislation, processing fees and forms on the website of the Finnish Immigration Service.
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.
