If your country is listed there. BLI will help you through the process and will send you the necessary school documents to submit with your application.
If you are planning to study at BLI for longer than six months, there are two documents you must have: a Canadian Study Permit and the CAQ (Quebec Acceptance Certificate). If this is the case, you have to apply for the CAQ first. After getting your CAQ ( 3-6 weeks in general), you can start the process of obtaining your Canadian Study Permit.
