Citizens of the United States, Canada, Ireland, Australia, and New Zealand, and British subjects, need a valid passport to enter Norway. You need to apply for a visa only if you want to stay more than 3 months.
A British Visitor's Passport is also valid for holidays and some business trips of less than 3 months. The passport can also include your spouse, and it's valid for 1 year. Apply in person at a main post office in the British Isles, and the passport will be issued that day.
Your current domestic driver's license is acceptable in Norway. An international driver's license is not required.
What You Can Bring Into Norway
With certain food exceptions (such as meat, meat products, and cheese), personal effects intended for your own use can be brought into Norway. If you plan to take them with you when you leave, you can bring in cameras, binoculars, radios, portable TVs, and the like, as well as fishing and camping equipment. Visitors of all nationalities can bring in 200 cigarettes, or 250 grams of tobacco and 200 sheets of cigarette paper, or 50 cigars; and 1 liter of spirits or 1 liter of wine. Upon leaving, you can take with you up to 25,000NOK ($3,850/£2,055) in Norwegian currency.
