Hello, SBW. We submitted our common-law inland sponsorship application on Nov 15, 2022 and received AOR1 on Nov 29, 2022. Medical and biometrics for principal applicant (PA) have been updated too as these were previously completed in the past for PA’s TRV extension application.
It is still in progress, of course, but it’s a bit of a relief receiving a few correspondence from IRCC acknowledging receipt.
As for the application itself, it was a DIY. Some questions were a bit tricky and required further research but overall do-able.
Per my research, hoping to receive SA next. Fingers crossed! Hope this helps.
