Hi,
May I know how did you link dependents PR card application in primary applicant's GC Key? In my case, primary applicant got PR card and his status in GC key got approved, mailed and received the PR card too.
But for dependents, Yet to receive the PR card. COPR - April 03. I have called IRCC thrice and they said, "it is yet to move. But I don't see any issues in your application". Still, I would like to track it. I tried to link using Application_number with UCI / only with names. But no luck. Can you share the options which you chose. TIA!
