Even if it's true that geography tends to filter out low-quality immigrants from Asia, those high-quality ones would still be discriminated against by the white guys. They probably are. How many Asians do you know that are CEOs of Fortune 500 tech companies? There's a well documented theme in the American Asian community that if an Asian and White guy are up for a promotion, the White will get it despite the quality of work by the Asian. Asians do fine on the front-line of professional positions, but they're horribly underrepresented in management (versus their numbers in the front-line).
