I don't know what your problem is other than being married to a criminal. I attempted to help you, but it was clear that you are withholding major facts and live in your own little world. I do believe that a felony conviction for conspiracy to commit a robbery is going to make your husband a agg.felon, under section INA Section 101 (a) 43 (G) if he was convicted of a felony, and sentenced to a term on 1 year or more in jail, less than that still makes it a CIMT. A crime, which is a misdemeanor under state law, but, if prosecuted under Federal Law, would have been a FELONY is an INS Defined AGGRAVATED FELONY. You still haven't explained how you are going in front of a IJ, but claim that he has never spoken to a immigration officer. I'm telling you, that is not possible! Remember this, I wasn't the one who made the first post asking for help.
I'm pretty sure that I know how this will turn out. Your Attorney is going to ask the IJ for Vol. departure under safeguards, rather than take a deportation. You will pay the cost of his flight home, he will fly to his country, then apply for a waiver of his criminal conviction, and submit a I-130 for his return. If you think he is going to walk out the door of a detention center a legal resident GC holder you are sadly mistaken. Maybe you should be seeing his consule about you getting a green card from his country...
Better start putting in extra hours at the gas station, your immigration attorney is going to bleed you dry..
BTW.. I didn't enjoy deporting people, and not every alien that I met got arrested, but every alien that I deported was a criminal who broke the law. For some strange reason, I have a mental picture of you, white, 5-6 inches tall, 250 lbs. plus, and wearing your best pair of sweat pants to court.
Be careful about asking advice, sometimes people don't tell you what you want to hear. Have you noticed that no one else is saying that I'm wrong about this but you?
