I know of a man staying in the US on a tourist visa who has plans to move here. I also know he has a small child, out of wedlock, with a woman living in England. His intention is to move to the US and avoid paying child support. He is working on this naive young girl to try and convince her to marry and sponsor him. I tried to report him to CSA but they said they needed a case number and I don't know the child's or mother's name in the UK. Someone needs to seize his passport, but I can't believe CSA will do absolutely nothing. What should I do to keep him from running away to the US and leaving his small child, unsupported in the UK?
