I am a US citizen (born and raised in US). My boyfriend, who I am very much in love with, entered into a fraudulant marriage to obtain his greencard before we met. During the interview his spouse revealed that their marriage was fraud. He has a hearing at the end of this month. We have spoken to lawyers and as we understand it he has two options: 1. prove that the marriage was entered into good faith or 2. voluntary departure. We are thinking of going with #2 but what exactly is the process and the limitations of voluntary departure? How long does he have before he must leave? Does voluntary departure trigger a ban? Also, if he were to leave voluntarily would I be able to bring him back on a fiancee visit and how likely would it be granted given his history of marriage fraud?
