I called IRCC today. It's weird that the agent told me that IRCC is actually waiting for a document to be sent from a "third party," not from me. She told me there's nothing to worry about from my end. But the truth is the status on my tracker says "waiting on you" for additional information. I can't do much, though. I don't even know what document is needed and what "third party" is involved. I'll just have to wait and see.
That is interesting. We used the web form to enquire, but got a response saying an email was sent to us on Feb 23rd and please check in your junk folder etc. But that is just the test invite and not related to the additional information request. Is 1-888-242-2100 the number to call, and how hard is it to get hold of an agent?
