My parents' application (submitted in Nov 2021) is being processed at the Mississauga office. There have been a few back and force since then (ADR, Medical, RPRF, and updated passport info) the last one was updated passport and RPRF in Jan 2023. The issue is that I can't link their application to my father's MYCIC nor can I link it to mine. I have contacted the visa office and submitted webform but nobody seems to know why I can't link their application. Any tip as how I can check their application status?
