I live in the U.S. without any immigration papers, after a visa overstay. I married a U.S. citizen and she filed the immigration paperwork for me, but I hadn’t told her I was already married. So we got in trouble for marriage fraud. I think I was supposed to go to court, but I moved to another state. Now someone would like to offer me a job and sponsor me for immigration. And I’ve gotten a divorce and have a new fiance, who is a U.S citizen and would probably help me apply for a green card, but I doubt the immigration people would believe me that this marriage was real. How big a problem will my past marriage fraud be?
