If you were married less than 2 years, his green card is conditional. Immigration will not do anything to him. When his green card expires at end of 2 years, he will need to file an I-751 with immigration to get the conditions removed on his green card. At this time he needs to show he is still happily married to you or that the marriage ended, but he entered into it in good faith and it just did not work out. He will need to proof that the two of you at least started off with a legit marriage. Such as utility bills, bank statements, insurance, etc...If his green card is valid for 10 years it is what I call the permanent green card. Not much you can do at that point. You can report it to investigations, but they probably will not bother with it. It is not what they consider top priority. They are more interested in the criminal aspect cases. Now, you can and I suggest that you put your side of the story in writing and route it to his file. Now, when he does apply to remove conditions, hopefully they will look twice at this case. STAY ON IT. Even if his card is NOT conditional, but your side in writing and route it to his file. When he applies for US Citizenship it should be questioned at the interview. Good Luck! And if he is still in contact with you, document and send to immigration to route to file.
