Also, we know that they go over applications in batch. What I mean is, they process December 2023 applications at the moment for example, then they'll move to January Applicants, in the meantime, CSIS and CBSA and other agencies will complete their check, then IRCC will do another round for December applications and pass their background check etc. etc. then the same will happen to january applications. You get the point. In total, many people receive only a few updates. AOR -> background/test invite -> LPP -> Ceremony. From my CSIS notes, I can tell that once you get AOR, they submit your info to CSIS. Maybe to other agencies as well, but I don't have proper resource to prove it, so IDK. So, if we assume that they process applications in batches, then it makes sense that they would assign us to some delayed files group I think.
