I have called CIC and they informed me that all I can do beyond what I've done is email CPC-Ottawa and Mississauga with my information and requests, which I did. I was also told it might be too late to withdraw the application, but many of you have said otherwise. I know sometimes the call center gives wrong information; they mostly just seemed unsure as they don't make the decisions. Someone on here said that a person on the forum canceled a sponsorship application while their spouse was on their way over on a flight to land. That's fast. Was that just a phone call? I would really like to know if anyone knows how they did it, because I have been told I have to wait for the visa offices to receive and process my emails. I can't call the visa offices, correct? CIC says my request to withdraw is not in the system yet, so I will have to wait. CBSA can do nothing for me until CIC acknowledges my request. All I have is confirmation that their offices received my emails, but I'm guessing that means nothing to CBSA.
I am not sure what to tell his parents. I would certainly tell them that it's already over and done and explain the conditional permanent residence (whether or not it applies to him--oddly, both the call center agents I've spoken with assumed it applies without even asking me when the application was sent or how long we'd been married). My only concern is that they might go to the border anyway, just to check and see what they can do. Or, failing that, at the very least his parents will have to cross the border to return to the US in a couple days, so they may ask--but I'm guessing they won't be given much information since it is in his private file.
Regardless, I would still really like to know if anyone has any information on the question I asked earlier about him crossing the border hypothetically (copy/pasting):
Say he does go to the border to sign, but he's denied because I withdrew the application and it's in the system at that point. He has to pass through to the US side and come back in order to get it signed (is my understanding). Would this mean that he won't be able to get back into Canada? Does he forfeit his visitor status extension when he crosses the border into the US? Or will they allow him to return?
I'm wondering because even if it's not in their system at the border yet, I could say it is and use this scenario as a way to stop him from going at all. I really am curious what would happen either way though.
