You can apply to be released from your Norwegian citizenship under 3 different circumstances:

• If you are living abroad and you are required to be released from your Norwegian citizenship in order to be granted citizenship in another country. 
• You live abroad and are a citizen of another country (It is not enough that you are registered as having emigrated from Norway, you must intend to remain abroad. You do not have to live in the country in which you are a citizen).
• You live in Norway, are a citizen of another country, and it would be unreasonable to refuse to release you (Such applications are only granted in exceptional circumstances. You must state why it would be unreasonable to reject your application. For example, wanting to avoid the obligations that follow from being a Norwegian citizen is not a valid reason).

How to apply

You must deliver an application letter and present a valid ID in person.

• Write a letter to UDI where you state that you wish to be released from Norwegian citizenship and on what grounds.
• Enclose documentation showing that you meet 1 of the 3 criteria (i.e. documentation showing either that you hold citizenship in another country or that you have been promised another citizenship which will be granted as soon as you are released from your Norwegian citizenship).
• Include a copy of the same ID that you will be using when you hand in your letter.
• Hand in your letter along with the supporting documentation:
  
  • If you live outside Norway, you will have to visit a Norwegian embassy or consulate general (external website). (external website)
  • If you live in Norway, you will have to go to a police station.

Releasing children from their Norwegian citizenship

Children do not automatically lose their Norwegian citizenship if their parents are released from theirs. It is also possible to apply for children to be released from their Norwegian citizenship, regardless of the child's age or whether the parents apply at the same time.
