Citizenship for adults

To prove your identity reliably, you need to present:

• your passport or some other identity document, or
• reliable information about at least your name, date of birth, citizenship and family ties
  • When we are determining your identity, we will also take into account any information you have given earlier about your identity. 

Read more on the page Determination of identity.

You must have at least satisfactory oral and written skills in one of the following languages:

• Finnish
• Swedish 
  • Finnish Sign Language or Finland-Swedish Sign Language. 

You must have a certificate of your language skills before you submit a citizenship application. For a list of accepted certificates, see the page Language skills.

You need to have lived in Finland for

• the past 5 years without interruption (continuous period of residence), or
• if your continuous residence in Finland has been interrupted, for 7 years in total (accumulated period of residence) after reaching the age of 15.
  • Out of these seven years, you must have lived in Finland for the last two years without interruption.

In some cases, a shorter period of residence is sufficient. Read more on the page Period of residence.

Offences for which you have been punished by petty fines do not prevent you from becoming a Finnish citizen. Read more on the page Integrity.

You have paid your taxes, fines and child maintenance payments, for example. Read more on the page Payment obligations.

You must present reliable proof of your means of support. The proof that you present must cover the entire period of residence required of you.

• For example: If the period of residence required of you is five years, you must provide documents on the means of support you have relied on during this five-year period.
