They will ask you to confirm name, uci, original entry date to Canada, last date entry to Canada, entry location for main applicant and dependent (if any). Then they will create an account in PR portal for you. I’m now waiting for their reply with this credentials so I can upload my photos and confirm mailing address. After this, they will confirm my address and photo then if everything is good an eCORP will be issued and the only step is to wait for PR to reach my hand. All these waiting will be gone
