What are the requirements and extensions for entering Thailand with a Norwegian passport?

Om du är Norsk och reser med Norskt pass så får du 60 dagar visumfritt.

If your passport is from Norway then you do not qualify for Visa on Arrival. You can receive visa exempt (not a visa) and you can apply one time for a 30 day extension.

Just hand your passport and your boarding pass to the immigration officer at the airport and they will give you your 60-day stamp.

Your airline might require you to show proof of a flight out of Thailand within 60 days of arriving. You would need to check with them if they have this requirement for people flying to Thailand without a visa.
