Norwegian nationality law

Norwegian nationality law is based on the principle of jus sanguinis. In general, Norwegian citizenship is conferred by birth to a Norwegian parent, or by naturalisation in Norway.

Norway restricts, but does not absolutely prohibit, dual citizenship.

In general, birth in Norway does not, in itself, confer Norwegian citizenship.

Regardless of the place of birth, a child acquires Norwegian citizenship at birth if either parent is a Norwegian citizen. Originally, citizenship was only passed on to the children of Norwegian mothers, as they were the only provable parents, but over time a presumption of paternal parentage created citizenship for the child, and eventually even excluded the maternal jus sanguinis. In more recent times, as of 1 January 1979, mothers' rights to automatically pass on their Norwegian citizenship has been reestablished. The requirement that the mother and father be married to one another was abolished on 1 September 2006.

Generally, it is possible to naturalise as a Norwegian citizen after residing in Norway seven years over the last ten years, if the applicant qualifies for permanent residence and does not have a criminal record.

Exceptions:

From 1 September 2008 an applicant for Norwegian citizenship must also give evidence of proficiency in either the Norwegian or the Sami language, or give proof of having attended classes in Norwegian for 300 hours, or meet the language requirements for university studies in Norway (i.e., demonstrate proficiency in one of the Scandinavian languages). From 1 March 2014 an applicant for Norwegian citizenship must also pass an exam about Norwegian society, laws and history.

A naturalised Norwegian citizen is generally expected to prove they have lost or renounced any former citizenship(s).

Norwegian citizenship may be acquired by notification to the Directorate of Immigration. This is a simplified form of naturalisation exempted from application fees.

As with naturalisation, a person becoming Norwegian by notification must normally renounce any other citizenship held, unless exempted.
