what was the reason for refusal if I may ask?
The usual stuff
• I am not satisfied that you will leave Canada at the end of your stay as required by paragraph R216(1)(b) of the IRPR. I am refusing your application because you have not established that you will leave Canada, based on the following factors:
• The purpose of your visit to Canada is not consistent with a temporary stay given the details you have provided in your application.
• Your proposed studies are not reasonable in light of your qualifications, previous studies, mark sheets, academic record, level of establishment, language abilities, and/or your future prospects and plans.
