Very disappointing that IRCC wait 4+ month to check the documents. They think our waiting times are not important. Resubmit your PR card application with new updated dates because it's been 90+ days since you submitted your first application. Attach a note mentioning that your application was returned, so if someone with a heart saw it could expedite it for you. No one knows when you will get the oath. It may be in a month or a year from now. I submitted my application Nov 2019, and still waiting the oath, and I don't think I will get it anytime soon.
