Hi there!
Thanks for your reply. Let me explain my situation so your knowledge in the matter can really help me. I have a valid study permit until July 2016 but my temporary resident visa is expiring next month so I have to re apply. I wonder if I can submit one application to extend both since I count with all documents including a letter for the university explaining the reasons why I want my study permit extended until September 2016.
Now about the fees. There is a page that details the fees (TRV for 100 and study permit extension for 150) then the list goes on like (TRV 25 if you already paid 75 before, which I did)
In any case, much appreciated if anyone can share an experience on this one.
