2close : Thanks for your advice. I hold a B1 visa to enter USA and, if required, I plan to change to M1 when I arrive. It shouldn't be a major problem for me. It is just that I wonder if I can get quality education from his program as claimed. And it seems like he tries to build it up like a franchise by offering to his students an Associate status with his school as free-lance instructors. Just wonder if it does work, especially on the quality control thing. Any comments on that?
