So we got married and filed the AOS packet before the 90 days was up. But I was wondering how we prove he's allowed to be here when the K1 visa technically had an expiration date after the 90 days. Is the paperwork stating that we filed our AOS forms sufficient? A social security card? Before the 90 days was up we'd gone to the dmv for him to take his permit test (he didn't drive in his country), and the woman was saying basically it would only be good until the date on our K1 visa, and after that he can't use it, for the permit and just an ID, but then said she was unsure. We didn't end up getting it that day since we needed a form from the eye doctor, but I'm unsure what to do. She'd told us to come back with all our forms and maybe it would be all fine, but we haven't yet since I'm worried about it being a big issue that the k1 visa 90 days is past. I believe we've done everything correctly, but I don't know how to prove it. Has anyone else ran into this problem?
