Wired News will give you some advice on how to get into professional gaming without moving to Asia.  Tech companies like AMD, nVIDIA and Intel are all offering sponsorships for teams, and there is serious money to be won, if you are good enough.
“But opportunities are opening up stateside as well, a trend that could accelerate as gaming tournaments in the United States find TV broadcasters and in turn bring in mainstream sponsors.
