I am afraid that as well meaning as you are, you are very naive about how this works. @Tod Danielshas given you the answer tight at the start of the thread. There are no lawyers who will be able to help and no large brown envelopes. Your so called friend has and is acting like a child. He needs to man up and take his ban by leaving via the airport immediately. Then after his ban is served and he grows up a bit, maybe he can come back.
