Many of you have given great advice on a myriad of topics, so I hope many of you can help me. My younger brother and his new wife were married this past October, after dating for 1.5 years. She's a Canadian citizen, and he's a U.S. citizen. They were recently married in Philadelphia, given a marriage certificate, and we would like for her to live in the U.S. permanently. Can his new wife stay in the U.S. during the paperwork process for her to become a legal resident? Or would she need to return to Canada? Her last entry into the U.S. was Sept, 2011, and her passport was swiped at the U.S. border. She is not sure how long she is allowed to stay in the U.S. I have tried to look for info online, and have tried to call INS, but everything seem to be so complicated, so any help would be greatly appreciated.
