• you are under the age of 18,
• you are not married or a registered partner, and
• you other parent does not have Norwegian citizenship.

• If you became a Norwegian citizen at birth, you will automatically lose your citizenship when you reach the age of 22 if you have not lived in Norway for long enough.
• This requirement only applies to people who became Norwegian citizens at birth, and not to people who were granted Norwegian citizenship later.

How can you avoid losing your Norwegian citizenship?

• To avoid losing your Norwegian citizenship, you must have lived in Norway for at least two years or in another Nordic country for a total of seven years.
• In order for a residence period to be included, it must have lasted for at least six consecutive months.
• If you have lived in Norway for long enough, you do not have to do anything to keep your Norwegian citizenship.
• You will not lose your Norwegian citizenship if losing it would leave you stateless.
• You can apply to keep your citizenship.

• If you are living abroad and must be released from your Norwegian citizenship in order to be granted citizenship in another country. 
  • In most cases, you will automatically lose your Norwegian citizenship when you are granted citizenship in another country. However, some countries require you to document that you have been released from any previous citizenships before they are willing to grant an application for citizenship. If you receive a decision stating that you have been released from your Norwegian citizenship, but you are not granted a new citizenship by the deadline stipulated by us, you will still be a Norwegian citizen.
• 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 deny your application. For example, wanting to avoid the obligations that follow from being a Norwegian citizen is not a valid reason.

• If you have been granted Norwegian citizenship, but you have not renounced your other citizenship by the deadline.
  • Norway allows dual citizenship in only a few cases. If you do not automatically lose your previous citizenship when you become a Norwegian citizen (whether this happens depends on the legislation in each country), the decision will normally state that you must renounce your previous citizenship within one year. If it is impossible to be released from your citizenship before a certain age, the one-year deadline runs from this time.
• The decision whereby you were granted a Norwegian citizenship is invalid.
  • If, during the application process, you have provided incorrect or incomplete information, or if you have intentionally withheld important information, and this was very important to the decision to grant your application, we can revoke your Norwegian citizenship.
