As a member state of the European Free Trade Association (EFTA), Norwegian citizens enjoy freedom of movement to live and work in other EFTA countries in accordance with the EFTA convention. Moreover, by virtue of Norway's membership of the European Economic Area (EEA), Norwegian citizens also enjoy freedom of movement within all EEA member states. The Citizens’ Rights Directive defines the right of free movement for citizens of the EEA, and all EFTA and EU citizens are not only visa-exempt but are legally entitled to enter and reside in each other's countries.
In order to travel to another country, a Norwegian citizen requires a passport, except within the Nordic Passport Union, where no identity card is formally required.
