Hi , so i finished studying August 20th 2023 and my study permit( paper) expires March 2024. they said you have 180 days from when your program ends to apply for PGWP but i just found out that study permit expires automatically within 90 days from when you finish your program even if your study permit expires after that. so now i think i am out of status even as my study permit expires March and i am still within the 180 days to apply. my question is , can i go to the border to apply(aka flagpoling). Please let me know.
