My husband a US citizen and I lived in my mother inlaw's house the time i got in US for 6 months then my husband received a job offer in Canada, we moved there for almost a year and i also gave birth to our son there but we always cross US border almost every month. Now my husband is currently in Afghanistan working from a US company and i went back to Philippines with our son for 5 months now. Now, my problem is, I want to go back to US to file the I-751 because my GC is expiring a month from now. Can i submit papers from Canada about the proof the we lived together? or I will get in trouble with that? like house lease and utility bills.. most of the proofs we have are the time we live in Canada. we only have a Joint tax in US. I'm afraid that's not gonna be enough.
