When you work and pay tax, you are an obligatory member of the national insurance scheme. It is your employer who is responsible for your membership of the national insurance scheme. You do not become a member
if you work temporarily for your foreign employer in Norway.
When you are an obligatory member of the national insurance scheme, you ordinarily have the right to health services and benefits from NAV.
You can read more about your rights and responsibilities as an unemployed person in Norway on Nav.no. This information is for people who are legally resident in Norway.
