Dual citizenship

Do you have any questions about other countries' rules?

If you are wondering about the rules for being granted citizenship in other countries, you must contact the authorities of the country in question or one of the country's embassies.
Citizenship rules differ from country to country, and the UDI can only answer questions about the rules that apply in Norway, not about other countries.

Who can have dual citizenship?

From 1 January 2020, it is allowed to have one or more citizenships in addition to a Norwegian citizenship. 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.

What does it entail to have dual citizenship?

You have the same rights and obligations in relation to the Norwegian state as other Norwegian citizens.
You are entitled to have two passports, one from each country.
In principle, you are entitled to consular aid and help from the authorities of both countries. However, it can be difficult for Norwegian authorities to help you if you are staying in the country in which you have your other citizenship.

In principle, as a Norwegian citizen, you are obliged to serve your military service in Norway, but the rules vary depending on which other country you are a citizen of. If you have questions about military service, you can contact the Norwegian Armed Forces (external website).

You must give notice if you become a citizen of another country

If you lost your Norwegian citizenship because you became a national of another country, make sure that this is registered in the Norwegian National Population Register.

If it is not already registered that you became a national of another country, you must send a letter to the National Population Register (external website) requesting this. You must attach documentation on when and how you became a national of another country.
If you are not sure whether this is registered, check with the National Population Register (external website). This must be properly registered before delivering the notification of citizenship.
