there's nothing you can do as his fiance, since a fiance petition is for nonimmigrant status and that would change nothing. if you have any hope of affecting his situation, you'd have to marry him and then file an I-130 immigrant petition. however, there are too many things here we know nothing about, so it would be dangerous to give you anything other than very general advice. go see a good immigration attorney and talk to him to see if marrying and filing a petition for him would actually have any beneficial effect. at least the attorney would have all the facts in front of him before giving you any advice, and that is something you very definitely need, an educated and informed opinion.
By the way, having 2 American citizen children is far from irrelevant under US immigration law, and could be very significant depending on where he's actually from. if you haven't already talked with an immigration lawyer, check into what his chances for getting suspension of deportation are.
