As an international student, you must maintain full-time enrollment (minimum course load) each semester to comply with study permit conditions. Failing courses or dropping below full-time can jeopardize your permit status and PGWP eligibility. If you need to take time off for medical or personal reasons, you must apply for a leave of absence through your university and potentially your study permit conditions. Unauthorized gaps can affect future immigration applications. Maintain good academic standing and communicate with your international student office immediately if you face challenges.
