you know that this case as you stated now is a tough one. get out of Jail looks like imporsible right now. It is beyond you, here and even most attorneies. be prepared for a long time on going case.
1. contact Chinese Consulate in New York. they won't help too much, but still they have right to know.
2. his wife go with or urthorize a leagal expert to find out the detail charge(s) (best in writing)
3. it might be FBI (DOJ) not the DOL (Dept. of Labor)
4. he might be convicted or pleade small offense at the end of the case after put his life under microscope or as a way of exit.
"如果最后的确是冤枉的，那么有赔偿法来赔偿，发财了。"
no way to get rich like upstair reply stated. just try to take care his health and a day passed is a day nearer to the release. it is more like your statement:
"It is not that difficult to get in jail ...and find some tiny problems on you."
