If you are a student at a folk high school or denominational college, you must in addition apply for a permit for part-time work, or full-time work in ordinary holidays.
When you apply for a renewal of your permit, your education provider must give a statement of the progression of your studies and if working part time is recomended
Statement of the progression of studies and part time work (in norwegian). The form must be completed by your education provider, and you (the applicant) must enclose it with the application.
