I applied for canadian temporary visa in 2018 alongside my son's application for study permit. My son was the principal applicant, which were granted. Now I am filling a form for PR. A question was asked, whether I have applied to IRCC before. I said yes. Then I was asked for my UCI. I could find my son's UCI, but wasn't sure if I got UCI number for my previous application. I want to find out if my son's UCI is the same for all of us that applied under him or we are supposed to have our own individual UCIs.
