One U.S. citizen accompanied another U.S. citizen to Bangladesh and married a girl in Bangladesh who is a Bangladeshi citizen. He registered the marriage with Bangladeshi law there and the accompanied person was a witness on his behalf during the marriage registration.
He came back to the USA after about three months, telling the girl that he would apply to have the girl come to the USA. But after he got back to the USA, he is saying he won't do this and threatening the girl not to communicate with him. He is not fulfilling the marriage contract. What is the solution to this problem?
