Have previously been Norwegian citizen or held a Norwegian passport
Want to apply Notification of citizenship for those who have previously been Norwegian citizens
You can submit a simple notification of citizenship if you have previously been a Norwegian citizen, and lost your Norwegian citizenship because you became a citizen of another country or did not give up your previous citizenship.
The applicant is the person who wishes to become a Norwegian citizen.
If you are a citizen of two or more countries, and one of them is an EU/EEA country, please choose the EU/EEA country.
Requirements for becoming Norwegian by notification
Please make sure that the following is in order before you start the application process
You must have previously been a Norwegian citizen. If you are not sure if you became a Norwegian citizen because your mother or father was Norwegian, you can check this in our guide. If you have previously been granted Norwegian citizenship with a requirement to release yourself from your original citizenship and then had your citizenship application rejected because you did not release yourself from it. Then, you have not been a Norwegian citizen. You must apply for a Norwegian citizenship again.
You must have lost your Norwegian citizenship for one of these reasons
you became a citizen of another country before 1 January 2020, or
you became a Norwegian citizen after applying for it, but you did not renounce your previous citizenship by the deadline you received from the UDI. If this applies to you, you have received a decision from the UDI.
You cannot have lost Norwegian citizenship because you did not live long enough in Norway before you turned 22. If you are unsure if you lost your citizenship for this reason, check this out in our guide.
Do you wish to be a citizen of more than one country?
From 1 January 2020, it is not a requirement that you give up your original citizenship to become a Norwegian citizen. You can have one or more citizenships in addition to a Norwegian citizenship. Even so, if the country you are a citizen of now does not allow that you have more than one citizenship, you can still lose this citizenship when you become a Norwegian citizen.
You must make sure what the rules are in the country you are now a citizen of. You can for example look for information on an official website which belongs to the authorities in this country or ask an embassy.
You do not have to inform Norwegian authorities that you wish to keep your previous citizenship.
