Unfortunately, that's the ground reality here. There were a couple of applicants who posted updates today and they were scheduled for oath in Feb 2022 (this includes one April 2020 applicant). I guess they are so overwhelmed with the backlog of 2019 applicants, who by the way are one of the unluckiest batch of applicants (unfortunately), that they've decided to schedule oath for 2019 applicants in the next 3 - 5 months and then continue with 2020 applicants. If this was their thought process, then it would be considered fair by 2019 applicants but 2020 applicants will experience delays going forward.
Based on this new information, it should be okay for you to travel but just make sure you renew your PR card before you leave Canada just in case there are unexpected delays and you aren't able to return before the PR card expires.
The 5 - 6 month wait would be painful knowing that their citizenship is so freaking close, yet so far. But at the end of the day, a confirmed oath date in early 2022 is still better than no oath date IMHO.
I sincerely hope that they find better ways to fix this situation and allocate oath dates that are more reasonable.
I have yet again requested information from their corporate records via the Access to Information Act to get an idea of what we're dealing with here and the progress that IRCC has made since Jan 2021. Details are in the post below =>
