I have been asked to send my original passport to IRCC office in Ottawa for completing my Express Entry Application by official IRCC email. IRCC call centre agents told me that my application has been approved; however, I did not get any letter uploaded on my application profile. I have seen other people had been asked to go for an interview, and during the interview the IRCC officials would confirm that they had received PR and make their existing work/study permit invalid by punching a hole in it. Then they would send the PR card my mail. However, in my case, none of these happened (so far). So my question is, do I just send my passport and wait for them to mail it back sealed with a Canadian visa along with the PR card? And do I need to send my original work permit as well?
