Can I travel abroad after I have become a Norwegian citizen, if I have not yet received my Norwegian passport?
It may take some time to receive your Norwegian passport after you have been granted citizenship.
When you are granted Norwegian citizenship, your residence card will no longer be valid even if the card has not yet expired. If you have a passport from another country, but do not have your Norwegian passport, be aware that it may be difficult to document that the visa rules that apply to Norwegian citizens also apply to you.
There is usually no passport control between Schengen countries.
When you re-enter Norway, you may have to document that you have legal residency in Norway at the border control. People with passports from outside the EU/EEA usually document this with a valid residence card.
If you travel without a Norwegian passport or Norwegian ID card, you may experience problems at the border control into Schengen/Norway, or at an ID check in another Schengen country. In other words, you may have difficulties re-entering Norway after your stay abroad.
What happens if I am abroad when I am granted my Norwegian citizenship?
Suppose you are granted Norwegian citizenship while being abroad. In this case, you should be prepared to answer questions when entering Norway about why you are still travelling with documents other than a Norwegian passport. You will then need to explain that you became a Norwegian citizen while abroad and, therefore, have not had the opportunity to get a Norwegian passport.
