Do you think he will get deported?

a man i know has been denied for his green card because they think he entered a false marriage. he appealed it and while he was appealing it, he got a domestic violence charge against someone(not his wife). Would immigration even tell him if he was denied again, or just deport him when they get their hands on him? His P.O. called him. He finished probation a few months ago, and his P.O told him to come in so he can finger print him again. Sounded kinda fishy. The domestic violence charges, even though he was found guilty, were not true. Is he going to get deported?
