I studied in Canada from Aug 2019 to July 2020 on my study permit. I applied for PGWP in Dec 2020 (Study permit was valid till Mar 2021). My country has three visa offices and I have no clue which office is my PGWP application being processed at. To raise a webform specific to the visa processing office I need to know which office my visa is getting processed at. How do I find this out?
