This doesn't surprise me. My file has finally gotten approved. However, I request ATIP notes from IRCC as advised by my MPP. I was shocked to find that the PF response I submitted had not been forwarded to CMAU for no apparent reason - all the notes said is "waiting for due date to pass before forwarding to CMAU". But the call from MPP's office triggered them to move the file and since then, ALL of the remaining steps were completed in less than 2 months. I wish you the best and hope things turnaround fast.There is no time limit. My parents file stuck in background checking from last 1 and half year. 3 medical has been done. Ircc completely silent and not give any response. Now my frustration increased on very high level. Because ircc is not taking seriousness no pgp file. Only student visas are granting in big amount.
