Danish nationality law

Danish nationality law is ruled by the Constitutional act of Denmark (of 1953) and the Consolidated Act of Danish Nationality (of 2003, with amendment in 2004). Danish nationality can be acquired in one of the following ways:

Danish nationality can be lost in one of the following ways:

According to Statistics Denmark, 3,267 foreigners living in Denmark replaced their foreign citizenship with Danish citizenship in 2012. A total of 71.4% of all those who were naturalized in 2012 were from the non-Western world. Half of all new Danish citizenships in 2012 were given to people from Iraq, Afghanistan, Turkey, Somalia and Iran.

In October 2011, the newly elected centre-left coalition government indicated its intention to permit dual citizenship.

On December 18, 2014, Parliament passed a bill to allow Danish citizens to become foreign nationals without losing their Danish citizenship, and to allow foreign nationals to acquire Danish citizenship without renouncing their prior citizenship. A provision in the bill also allows former Danish nationals who lost their citizenship as a result of accepting another to reobtain Danish citizenship. This provision expires in 2020. A separate provision, lasting until 2017, allows current applicants for Danish citizenship who have been approved under the condition they renounce their prior citizenship to retain their prior nationality as they become Danish citizens. The new law came into force on September 1, 2015.

Anyone with Danish citizenship may nonetheless be required to give up foreign citizenship under the laws of some countries. For instance, people who are Danish-Japanese dual citizens by birth and want to keep their Japanese citizenship must, under Japanese nationality law, make a declaration of choice to the Japanese Ministry of Justice before the age of 22 that they want to keep their Japanese citizenship (Article 14, Part 1). This process will not automatically void the Danish citizenship, because the Japanese Government has no power to cancel Danish citizenship. However, anyone who declares to retain Danish, rather than Japanese, citizenship under such circumstances will automatically lose the Japanese citizenship (Article 11, Part 2).
