I am from Pakistan. I got my student visa for Canada in 2017 . I went there but didn't join college. I had to come back to Pakistan. I asked the college for a refund, stayed there for 3 weeks and came back. I wanted to know if my visa is still valid and can i still do to Canada by simply getting an admission in some university and land to Canada. Or my visa has been cancelled. Note: It hasn't expired yet.
