I have talked with the International student Advisor, She deferred my admission to Sep 2023 which was Jan 2024 earlier.
Advisor Information:
If the student is not registered for college when already in canada. The student should defer the admission to next semester. The study permit allows upto 150 days or next semester to stay in Canada, whichever is sooner. If he fails to get admission for the following semester, Get yhe admission for the available semester and the student has 2 options.
1. The student should leave canada and come back when the deferred semester starts.
2. The student should change the status to Visitors visa before 150 days. And when the semester starts , he/she can continue using the existing study permit to continue the study.
