Our daughter is dating an illegal immigrant from Mexico. He crossed the border illegally and was never inspected, has no kind of papers or anything. He is working in the U.S. using a fraudulent SS card/number. We were recently told by a local attorney that the only possible way for him to become legal in the U.S. is for him to return to Mexico (undetected) and apply and follow the legal procedures. We were told that marriage does not help his situation in any way; that even if they were married, he would have to follow the same steps. We are discouraging her involvement with him and want legal information to back our concerns. Please advise if you concur with this information.
