For some reason, sending/receiving the Sponsor Approval letter seems glitchier than the other steps in the process. For one thing, they usually don't send it until after the PA's eligibility is also approved, so you often see people getting it after they receive AIP (and AIP implies SA because you can't have an eligible spouse if you're not eligible as a PR or citizen in the first place). The other thing is it often "gets lost" when sent as an email or it gets inexplicably sent in the physical mail (even when the sponsor has received AOR by email so clearly IRCC has the correct email). IRCC is so weird and glitchy.I called yesterday just to poke around and they said nothing exciting other than that my sponsor was approved July 22? I mean I’ll take it but I didn’t receive anything.
