The applicant is the person who wish to visit or live in Norway.
If you come from a country outside the EU/EEA and wish to work in Norway, you need a residence permit. If you do not already have a residence permit, you must apply for a residence permit for work. Previously this was called a work permit. This may for example be a residence permit for skilled workers, ethnic cooks, seasonal workers, self-employed persons or employees in a humanitarian, non-profit or religious organisation.
