Hi there,
We are in this situation right now. My parents received PPR on Feb 7 while they are in Canada. Application was submitted when they were in their home country. I called IRCC and they asked me to submit a web form with Delhi visa office if they can allow passport stamping in Canada, waiting to hear back , not sure what will happen if we don’t hear prior to 30 days timeframe to submit passports. I submitted multiple web forms prior to their arrival too but no specific response. Did you submit passports in Canada recently? Did you need to contact IRCC for any confirmation prior to submitting?
