Sherry is a single mother who says she married David in Nigeria two years ago and hasn’t seen him since their honeymoon. She says that after three attempts to get him a U.S. visa, she needs to know if David is ever coming to America. Sherry’s sister, Robin, says she suspects their marriage is a scam, which David adamantly denies.
