I am a swiss student (Citizenship + Nationality + Place of Birth: Switzerland) and I just got accepted by a PhD program at the University of British Columbia (UBC), Canada. There are tons of information online but I don't manage to make sure which kind of Visa I should apply for.

Should I apply on this page for a study permit or for a permanent resident status?

Notes: I will be working as a Teaching Assistant (TA) at UBC. I have never studied in Canada (only in the USA as an exchange student during my Bachelor).

Thank you!
