Can I travel abroad after I have become a Norwegian citizen, if I have not yet received my Norwegian passport?
After you have been granted Norwegian citizenship, it may take some time before you receive a Norwegian passport.
When you are granted Norwegian citizenship, your residence card is no longer valid, even if the card has not expired. Suppose you have a passport from another country and do not have a Norwegian passport. In that case, you must be aware that it can be difficult to document that the visa rules that apply to Norwegian citizens also apply to you.
There is usually no passport control on travels between Schengen countries.
When you re-enter Norway, you may have to document that you have legal residence 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 a travel document / alien's passport / other country's passport and residence card and do not have a Norwegian passport. You must then explain that you became a Norwegian citizen while abroad and therefore have not had the opportunity to get a Norwegian passport.
