"Permission for activity outside status" exists because a student visa (D-2 etc.) is issued for the purpose of study, not employment, so any paid work falls outside that authorized purpose unless immigration separately approves it. The permit specifies allowed weekly hours, often stricter during the semester and looser during vacation, and ties the approval to the specific school enrollment.
Assuming "no permission is needed" is the trap — working without approval is illegal even for a student visa holder and can lead to fines or visa problems. Permanent residency is a completely different, much harder-to-obtain status and isn't required just to do part-time work.
Because the hour caps depend on semester versus vacation, many students plan their part-time schedules carefully around exam periods to avoid quietly exceeding the legal limit.
