If you are a refugee claimant or a visitor, if you want to study at a post-secondary school in Quebec, you need a CAQ (Certificat d’acceptation du Québec), which is a study permit. If you are not a citizen of permanent resident (accepted refugee), you have to pay a lot more fees, because the government considers you an international student.
