Danish Citizenship

The rules concerning Danish citizenship are described in detail on the website of the Danish Ministry of Immigration and Integration


Dual Citizenship

On September 1, 2015 a new Nationality Act concerning multiple nationality came into force. The law means that:

  • Danish nationals who wish to acquire a foreign nationality may do so without losing their Danish citizenship. In this regard they do not need to take any action in relation to the Danish authorities.

  • Former Danish citizens, who have lost their Danish nationality by acquiring a foreign nationality can reacquire their Danish nationality by making a declaration to the State Administration (Statsforvaltningen), provided they fulfil certain requirements. The declaration must be made from September 1, 2015 up to and including August 31, 2020.

  • Foreign citizens, who are included in a bill on naturalization, are no longer required to renounce their previous nationality.

For more detailed information regarding dual citizenship, please see the following websites:

Children born abroad

Children born after July 1, 2014:

Previously, a distinction was made between children born in and out of wedlock when the child was born abroad. In that case, if only the father was a Danish national, the child had to be born in wedlock to become a Danish national by birth. As of July 1, 2014 the Law on Danish nationality changed to the effect that a child acquires Danish nationality by birth if either the mother or the father is Danish, regardless of whether the child is born in or out of wedlock. The child also acquires Danish nationality if the co-mother is Danish.

Children born to a Danish father and a foreign mother between between October 11, 1993 and June 30, 2014 may July 1, 2014 may apply for Danish citizenship. For detailed information, see Børn født uden for ægteskab af en udenlandsk mor og en dansk far (section 3)

The 22-Year Rule – Retaining Danish Citizenship beyond the age of 22:

According to the Danish Nationality Act, any person born abroad who has never been resident in Denmark nor stayed in Denmark under conditions indicating some close association with Denmark shall lose his/her Danish nationality on reaching the age of 22, unless this will make the person concerned stateless.

An application to retain Danish citizenship should be submitted to the Ministry of Immigration and Integration before the age of 22. Due to the relatively long processing time for retention applications (10-12 months), the Ministry of Immigration and Integration will accept applications according to the following timeline:



  • Between the age of 21 and 22: If your original documents are from countries, where an apostille certification is not needed. This includes official documents from Denmark and the United States.

  • Between the age of 20 and 22: If your original documents are from countries where an apostille certification is needed.

Please see the following websites for detailed information re. retention of Danish citizenship and document requirements:

The application can be submitted to the Ministry of Immigration and Integration directly. You may also submit the application via your embassy or nearest consulate for an additional handling fee.



Please note: When applying for a Danish passport, Danish citizens born abroad and above the age of 22 must show a certificate of citizenship or be able to document that have fulfilled the residency requirements for retention. In order to avoid delays, all Danish citizens born abroad are strongly encouraged to apply for retention of/proof of their Danish citizenship.
