So if we submit that form through webform how long will it take for them to give the response?
Are you saying we have to submit it while we are on the call?
You can download this form and submit through the web form and IRCC takes 24 hours to validate this form. They will send you an email as well that they have validated the form and you are authorized to have access about PA's file.
I didn't know that before, I called IRCC and agent told me about it. While I was on the phone call with the agent she asked me for the email address and sent me the form same time. Next day I submit the form through the web form with PA's signature on it. Within 24 hours they have validated it.
