Is my U.S. marriage really a "fraud" if I didn't divorce my first wife?
I was married in my home country, but haven't seen or heard from my wife for years. I'm not even sure how to reach her. We never bothered to do the divorce papers. I came to the U.S. and married a U.S. citizen, and we submitted the adjustment of status paperwork for me. But at the interview, the officer sent us away with a letter saying I needed to provide proof that my first marriage ended in divorce, and she also mentioned something about "marriage fraud." But I love my U.S. wife; this isn't a fraud, I just figured my old marriage was over. What's going on?
