Can I travel to and from Norway if I applied from Norway and I am from a country where no visa is required for travel to Norway?
If you travel to and from Norway after you applied for family immigration, you must follow the rules for visiting Norway without a visa. For example, if you have been in Norway or another Schengen country for 90 days or more, you will have to stay outside the Schengen area for 90 days before you can travel back to Norway.
When you travel back to Norway, you could choose to stay in Norway until your application has been assessed – if you had the right to apply from Norway in the first place.
Be aware that staying in Norway beyond the 90-day visa-free period might be considered «overstaying», which could create problems the next time you intend to enter Norway via another Schengen country.
