Yes, we submitted a criminal rehabilitation application in the same package as the spousal sponsorship application. We haven't received any update to state that the CR has been approved. I saw some other posts in this forum mentioning though that sometimes when the CR is submitted together with the PR, the IRCC doesn't give an update to when the CR is approved. We haven't applied for GCMS or CBSA notes yet, but given that even the MP can't get an update on our case status, we are considering it now.
Yes, our lawyer told us to expect our application to take over 12 months to process... we were hoping that maybe with some government pressure, our case could be finished processing by the end of 2020 at least... now with pandemic delays, that might even be too much to ask sadly.
Yes, that's true. Sometimes rehab applications are approved separately and sometimes it happens together at the end.
The government pressure thing won't work / isn't possible. MPs can inquire about the status of an application but they cannot influcence processing. The most your MP will be able to do is find out status.
I would order your GCMS notes. That will give you the best idea of where things stand.
