Yes, I am in Canada now. sent the docs to IRCC and waiting on them.Did you return to the US after submitting the documents? I will be in a similar situation but will be in Seattle, a driving distance from Canada. Did you update your address to your US address?
I am hoping to get some response but I am scared that it may take months for them to get back to me on it.
I will update the forum as soon as I get any reply. so, it can help other ppl to take the decision based on my experience.
