As Canada.ca says that study permit will expire in 90 days after receiving completion of program letter. My study permit valid date is until July next year. I received my completion letter last week. I will apply for PGWP in few days. So my question is: Although my study permit date is valid for 9 months, do I still have to follow 90 days rule after I apply for PGWP?Do I have to extend my study permit during the period of waiting PGWP(my study permit is still valid for 9 months, which is enough for waiting PGWP. But 90 days is not long enough. so Im so confused.)?
