My wife and I got married last month, and her K1 status expired yesterday (her I-94 says "Class K1 until Nov. 18, 2008"). We just sent in her I-485 AOS application last week, so we haven't received the I-797 receipt from the USCIS yet. I know, we should've sent in the I-485 sooner...my bad.
Anyway, we're flying to Boston next week for Thanksgiving, and the only form of ID my wife has is her foreign passport. Will she be ok at the airport with that? I'm afraid they'll flip to the visa page and see that her K1 status has expired and not let her on the plane. I have our marriage certificate which shows that we got married within 90 days of her arrival into the US. Will that be sufficient?
