Also what sort of acknowledgment did you receive from IRCC .
1. Was it an email confirmation that they have received the webform or - > Yes
2. Was there any updation on your GC key portal with the new LOA - > No
3. Is your study permit duration changed or its the same? - > Yes, it has been updated.
Your study permit duration is increased or its decreased?
Actually, in my case, I have also deferred from JAN 21 to SEPT 21 and I have received the study permit till APRIL 2023.
To be specific my JAN intake offer letter specified 24 months of studies and based on that I received this duration of the permit.
And my new offer letter specifies 16months of duration so are there chances that my study permit duration will decrease?
Note: My passport is stamped with the duration of my study permit.
