Yes, you can report it to INS
Speak to an attorney before you do anything. If you are working and employed, the company\'s failure to pay you is clearly illegal but if you have been terminated (or if there is any way that the company can claim that you were terminated) you may have a bigger problem. The company will (probably) still be on the hook to pay you until the visa is cancelled but you will have a much more difficult time of it.
