After my post graduation work permit in Canada I got 2 year study visa, during 1st semester of my program I got sick then I withrawn from college and left Canada without taking TRV visa. So now my study permit is valid for another 15 months, I am wondering if I get approved from Canadian college for study of 1 year program then do I need to do whole process again from India for study visa or just I need to get TRV? Please help?
