If you are an EEA national and have a valid identity card or passport, you have a right of residence for three months in Norway. The same applies to members of your family who are also EEA nationals.  Family members who are not EEA nationals must have a valid passport and be able to document that they are a member of your household or that they are supported by you.

If you are an employee from Bulgaria or Romania and have not had a residence permit in Norway in the last 12 months, special transitional rules apply. You need to apply for a residence permit then.
