Working in Norway is a great way to earn some extra money, learn the language and the culture.
There may be some restrictions to working though, so check this out first: Generally, a student residence permit does not cover the right to take employment in Norway.
However, if you are granted a study permit, you are automatically also granted permission to work part-time. EU/EEA students do not need a work permit, and can work in Norway after they have registered with the police.
Non-EU/EEA students can work 20 hours pr week during their first year of study. Beware that when renewing the study permit the part-time work permit is not automatically renewed. To renew the work permit the students have to document satisfactory progress in their studies. Please consult your institution.
