PGWP expires in May. Applying for extension knowing it will get rejection. However the process time should take 3-4 months which can help me since I can work under implied status. After the rejection, I will go home and stay there until I can get PR or a new study Permit. My question is after the extension rejection, how long do I have to leave Canada. Is it the same day I go out of status or there is a grace period of 30-60 days to leave Canada ?
