How can you turn someone in for marriage fraud you have extensive proof video audio tape of this person having sex and admitting to this illegal action?
Turn the evidence into your local DHS immigration department.
Can a us Citizens be charged for marring a illegal immigrant because they love them and not trying to make them legal?
I don't understand your question. Marriage fraud to violate immigration law is illegal and a felony. It is illegal to marry someone to make them legal. It is not illegal to marry an illegal immigrant because you love them. It is not illegal for you to immigrate your illegal spouse...assuming that the marriage is legitimate. It is illegal to mar them.
