Subject to certain conditions, citizens of Finland, Iceland, Norway and Sweden (Nordic citizens) can acquire Danish citizenship by submitting a declaration to the Danish Ministry of Immigration and Integration, the High Commissioner of the Faroe Islands, or the High Commissioner of Greenland. 

Nordic citizens, who have turned 18 years old, can acquire Danish citizenship under certain conditions.

Additionally, Nordic citizens, who have turned 18 years old but are not yet 23 years old, can also acquire Danish citizenship by declaration under conditions specific to this age group.

Nordic citizens aged 18 to 22

Nordic citizens aged between 18 and not yet 23 can acquire Danish citizenship by submitting a declaration.

If you fulfil certain conditions as a Nordic citizen and are aged between 18 and not yet 23, you can acquire Danish citizenship by submitting a declaration.

You can acquire Danish citizenship by submitting a declaration if you are a citizen of Finland, Iceland, Norway or Sweden and you:

  • are aged 18 to 22 years
  • have a place of residence in Denmark at the time you submit the declaration
  • have had a permanent place of residence in Denmark for a combined total of at least ten years, including at least five years during the past six years
  • have no criminal record and have not been sentenced to measures under Chapter 9 of the Danish Penal Code
  • have not been charged with a criminal offence. 

When determining the period of residence, emphasis will in the first instance be placed on the information recorded in the CPR register. However, the actual date of entry into Denmark will be used as a basis. The decisive factor is whether you have had a place of residence in Denmark for at least ten years. Holidays, etc. abroad are excluded from the determination of the ten-year period. However, holidays will be taken into account when determining whether you have been resident abroad for more than one year during the past six years.

The ten-year period of residence need not be continuous. The residence requirement is considered to be met if, for example, you lived in Denmark from birth until the age of five and you have also lived in Denmark for five of the past six years before you submitted the citizenship declaration.

The residence requirement is also considered to be met if you have had a place of residence in another Nordic country, but only if the period of residence in the other Nordic country dates back at least five years prior to submission of the declaration and was before your 16th birthday.

When determining the period of residence outside Denmark, emphasis will in the first instance be placed on the information registered in the CPR register and the information which the applicant provides under oath on the declaration form. All periods of stay abroad during the relevant period will be taken into account in the calculation. Departure and return dates will be taken into account. Weekend stays away will not be taken into account.

If you wish to submit this declaration concerning Danish citizenship, you must not have been charged with a criminal offence. If you have been charged with such an offence, you will therefore not be able to acquire Danish citizenship by submitting a declaration. If you have been charged with a criminal offence but the case has not yet been concluded, you will not be able to submit a declaration until you have been proven to be innocent.

You will be able to submit a declaration within one year after a final decision has been announced in the court case. This also applies if you are aged 23 or over before the end of this year.

More information

A child must fulfil certain conditions in order to acquire Danish citizenship with a parent.

Your children will normally be covered if you acquire Danish citizenship by declaration.

If you acquire Danish citizenship by submitting a declaration to the Ministry of Immigration and Integration, the citizenship will normally also cover your children, provided:

  • that youhave sole or joint custody,
  • that the other parent has given their consent,
  • that the child is unmarried and
  • that the child is under 18 years of age.

In the case of adopted children, it is a further condition that the adoption is valid under Danish law. Note that documentation of the validity of the adoption under Danish law must be obtained and attached to the declaration.

You can also state that you do not wish your children to be covered by the citizenship.

Note that the relationship of the children who are covered must be documented. This may require you to undergoa DNA test or to submit original apostille-endorsed or legalised birth certificates.

If, as a Nordic citizen, you do not fulfil the conditions for acquiring Danish citizenship by submitting a declaration, you can apply for Danish citizenship by law (naturalisation) instead.

Nordic citizens must normally fulfil the general conditions for acquiring Danish citizenship naturalisation. However, special rules apply to Nordic citizens as regards the requirement for an indefinite residence permit and the residence requirement.

It is possible to have both Danish citizenship and another citizenship.

Denmark has accepted dual citizenship since 1 September 2015.This means that, if you are a Nordic citizen and become a Danish citizen, you will retain your Nordic citizenship and thereby acquire dual citizenship.
