Hi If my son has a study visa which is valid for another 15 months can he land in canada with a letter of acceptance from any college? He did not pursue with the first college that led to this study visa He got a refund from that college ! Now he wants to use the study visa to study in another college…can he proceed or will have issue at port of entry/upon arrival Thanks
