Calculating the residence period in citizenship cases (residence permits)


If you are going to apply for a Norwegian citizenship, you must check that your residence period in Norway is long enough and that your stay has been continuous.

The permits must be of a certain duration in order to be included

The main rule is that you must have stayed in Norway with residence permits of at least one year's duration in order for the period to be included in the calculation of the residence period.

We can make exceptions from this requirement and also include permits of shorter durations if you have held

  • a family immigration permit that was valid for less than one year due to the duration of the permit of the person you were reunited with, or
  • a residence permit to work that was valid for a shorter period due to the duration of the employment relationship, but that nevertheless formed a basis for a permanent residence permit (this will be stated in your decision)

What date do we reckon the residence period from?

  • If you were granted a permit before you came to Norway, your residence period is reckoned from the date you came to Norway. If you cannot document when you travelled into Norway, your residence period is reckoned from the date on which you were registered by the police or the Population Register.
  • If you were granted a permit after entering Norway, your residence period will be reckoned from the date on which you applied for a permit.

What is not included in your residence period?

  • the time from your permit expired until you submitted a new application
  • illegal stays in Norway
  • stays abroad lasting for more than two months per calendar year

If you have stayed abroad for up to two months during one calendar year, that will have no bearing on the calculation of your residence period. This means that such stays abroad are regarded as residence in Norway, and time spent abroad will not be deducted. If you stay abroad for more than two months during a calendar year, however, the whole period abroad will be deducted, not just the part that exceeds two months. This is also the case if you were working abroad.

Special rules for stateless applicants over the age of 18

If you are stateless and over the age of 18, you must have resided in Norway continuously for the past three years holding permits of at least one year's duration. This means that you cannot have been

  • abroad for more than two months per calendar year in the past three years or
  • without a valid permit for more than two months in total during the past three years.

'The past three years' are reckoned from the date on which we made a decision in your case.

Special rules for children over the age of 2 who have a Norwegian parent or who apply together with one of their parents

If you are over the age of 2 and under the age of 18 when you apply for Norwegian citizenship, and you have a Norwegian parent or you apply together with your mother or father, you must have stayed in Norway continuously for the past two years holding permits of a duration of at least one year. This means that you cannot have been

  • abroad for more than two months per calendar year in the past two years or
  • without a valid permit for more than two months in total during the past two years.

'The past two years' are reckoned from the date on which we made a decision in your case.

If you have not yet turned two when you apply, there is no requirement for residence period, but you must have applied for or have been granted a residence permit before we can process your application for citizenship.
