Like all the countries in Europe, nothing could be easier than planning a trip to Norway. This will please anyone who hates endless paperwork.

If your passport describes you as a British Citizen you won’t need a visa to enter Norway. So it will be very easy to plan your next trip to Norway.

Norwegian authorities will accept British passports extended by 12 months by British Embassies and Consulates under additional measures put in place in mid-2014. For stays of longer than 3 months, contact the Norwegian Embassy for further information about entry requirements. UK Emergency Travel Documents (ETDs) are accepted for entry, airside transit and exit from Norway. You can renew or replace your passport at any time.
