Has anyone applied for the AIPP permanent residence application via the online portal - 
https://prson-srpel.apps.cic.gc.ca/
I wanted to know the following:
1. How do we upload the photos? Do we still need to upload the backside of the photo with details on it?
YES, FRONT AND BACK SIDE
2. Do we need to provide reference letters from the spouse's employers as well?
DO NOT NEED
3. My spouse and I have applied for the PCC, but it is still in process. I have added an LoE along with the PCC application as proof. Does the portal allow us to upload more documents later?
NO. MAYBE YOU CAN UPLOAD AFTER GET AOR AND LINK TO YOUR ACCOUNT.
Thanks
