We can only theorize/hypothesize on this forum about how they, at IRCC process our applications. From what I observed here on the forum there are people who submitted their applications in December, 2021 and their applications are almost finalized and there are people who submitted their applications in October or November of 2021 and they didn’t even get an AOR yet. That makes me think that they don’t process applications by the date submitted, right? I don’t have any insight into the process, just my own observations. I think that all these case workers/immigration officers whether they work in the office or remotely they log into the system and pick a certain amount of file numbers at random (from the huge pool of the backlog) to work on during a certain period of time, let’s say from number F000843700 to F000843750. Those case workers who work on family sponsorship applications work possibly on spousal+ dependents applications as well and those always precede the applications for parents and grandparents. So I believe that if they start processing someone’s PGP application but also get a spousal application to work on shortly after, they automatically put the first one aside to complete the spousal one and then get back to the PGP one. Again, we’re just hypothesizing here.
