The only way a Mexican national can come to the U.S. (and my immigration law is somewhat hazy) in order to set-up a trucking company is to demonstrate to the immigration authorities that 1. he provides a unique service in demand (not), and 2. he has statutorily-set boatload of cash to invest (not). In other words, there is no legal way to do it, other than buying stock in an already-existing American trucking company.
In sum, you have been deliberately led to confuse cross-border trucking with trucking in general. Whoever did it succeeded mightily.
