Finnish citizenship
Follow the instructions on this page if you have applied for Finnish citizenship before 1 October 2024. The Citizenship Act was amended on 1 October 2024, and the period of residence which is required for acquiring Finnish citizenship was extended. If you apply for Finnish citizenship on 1 October 2024 or thereafter, follow the instructions on the page Period of residence.

Period of residence: application submitted before 1 October 2024

You can become a Finnish citizen if you live in Finland and if the total time you have lived in Finland (your period of residence) is long enough.

You have lived in Finland long enough if

  • you have lived in Finland for the past five years without interruption (continuous period of residence), or
  • you have lived in Finland for seven years in total, with the last two years without interruption (accumulated period of residence).

If you have had a temporary residence permit (a B permit): 

  • Half of the time you have lived in Finland with a B permit before getting an A permit will be counted towards your continuous period of residence.
  • When you apply for Finnish citizenship, you must have either a valid continuous residence permit (A permit) or a permanent residence permit (P permit).
  • You must have lived in Finland with either a continuous or a permanent residence permit (A or P permit) for at least one year before your citizenship application is decided.

In certain situations, living in Finland for less than 5 years is enough

The period of residence required of you is shorter if any of the following conditions applies to you.

How to calculate the period of residence

To calculate your period of residence, you need to know:

  • how many years you need to have lived in Finland
  • when your period of residence started
  • whether you have lived in Finland for a continuous period or whether there have been interruptions in your residence.
    • If your continuous period of residence in Finland has been interrupted, you need to calculate your accumulated period of residence.

When does the period of residence begin?

The start date of your period of residence depends on the permit you had when you moved to Finland.

Interruption in the period of residence

Continuous period of residence in Finland

Your continuous period of residence is interrupted in the following situations: 

  • You move away from Finland.
  • You live outside Finland for more than a year.
  • Your residence permit expires before you apply for a new permit.
  • You travel outside Finland more than the limitations related to the period of residence allow.

How travels affect your period of residence

Short trips abroad do not cause interruptions in your period of residence in Finland. However, your continuous period of residence is interrupted if

  • you stay outside Finland so often and so long periods that you are considered to live mostly outside Finland.

The reason why you have lived abroad is not relevant, except when there is a well-founded personal reason. Your period of residence is interrupted if, for instance, your Finnish employer has sent you abroad on assignment and the period of absence from Finland is too long.

Trips that last less than six months

The following periods of absence from Finland do not interrupt your continuous period of residence:

  • trips that last a maximum of one month
  • a maximum of six periods of absence that last 1–2 months each
  • a maximum of two periods of absence that last 2–6 months each. 

Trips and absences that last over six months

One trip that lasts 6 to 12 months does not interrupt your period of residence but the trip is not counted towards your continuous period of residence. 
A trip that lasts over 12 months interrupts your continuous period of residence. If there is an interruption in your period of residence in Finland, the time periods you have lived in Finland will be counted towards your accumulated period of residence.

Well-founded personal reasons

Your period of residence in Finland is not interrupted if your absence is caused by a well-founded personal reason. The reason must be exceptional and unexpected, preventing you from returning to Finland. One such reason can be, for instance, a sudden illness that begins abroad.

The following are examples of reasons for absence that have not qualified as well-founded personal reasons: 

  • studies
  • work 
  • taking care of your ill parents abroad.

Accumulated period of residence in Finland

If there is an interruption in your continuous period of residence in Finland, an accumulated period of residence will be calculated for you.

  • Your accumulated period of residence may consist of several periods during which you have lived in Finland. 
  • You must have lived in Finland for at least seven years in total. In some situations, six years of accumulated period of residence is sufficient. 
    • You must have lived in Finland for the past two years without interruption, meaning that you have not moved away from Finland during that time. 
    • Holiday trips abroad are allowed but there is a limit for their durations: In total, you may spend four months outside Finland during the two years preceding the decision on your citizenship application.
  • Only the time you have lived in Finland after reaching the age of 15 can be counted towards your accumulated period of residence in Finland. The time you have lived in Finland with a temporary residence permit (a B permit) is not counted towards your accumulated period of residence.
