Defer from Fall 20 to Jan 21 - New LOA with Increased Fee

[mashwani]

Hi everyone. I applied for Fall 20 on 28 July, but I didn't receive my AIP yet (did receive one on Sep 3, but IRCC reverted it on 4th), so I deferred to Jann 21. Now I have received my new LOA, but college has increased the tuition fee. I have applied under SDS, so already paid my first year fee. Do I first need to pay the remainder of new fee balance first, and then upload my new LOA? Or I can simply upload my new LOA, and pay the remaining fee balance in the meantime?

Thanks for your help.
