Registration of citizenship
You can have several citizenships recorded in the Population Information System. We can record your citizenship in the Population Information System based on a valid passport, an original decision on naturalisation or some other reliable evidence.
If you are a Finnish citizen, you have the obligation to notify the Finnish Population Information System of the foreign citizenship you have received.

If you are applying for Finnish citizenship, contact the Finnish Immigration Service.
Which documents can I use to prove my citizenship?
- We will enter the date on which you received your citizenship as the date of receiving citizenship.
- Verify whether you need to have the decision legalised and/or translated. Read more about the legalisation of documents. Legalisation is not required if you present us with the decision and your new passport at the same time.
- Submit the original document or a certified copy of it.
- We usually enter the date on which the passport was issued as the date of receiving citizenship.
- Do not send your passport to us by post.

See more detailed instructions for delivering documents.
Required documents:
- notification form for correction of registry data which you have filled in

3. Inquiries and email messages will not speed up the processing of notifications. We will contact you if we need further information. You will receive a confirmation from us once the citizenship information has been recorded. Check that your information has been entered correctly. If for some reason we do not record the information you have submitted in the Population Information System, you will receive a decision on this. Instructions for submitting a request for administrative review are attached to the decision.
N. B.! Cases are processed in their order of arrival. Unfortunately, we cannot speed up an individual case unless there is a very exceptional and very important reason for doing so. For example, opening a bank account is not a sufficient justification for speeding up the process.
