My friends in political science are doing their masters research in "How americans view no white immigrants??" and they had to get approval from government for the thesis as it was a sensetive issues. the research is really really well done, for protection of my identity, i cant give the link to that thesis as of now. Some of the points they found on why americans dont like colored immigrants "specially asians" were: 1) Bring in very unusual culture, dress style etc, 2) these immigrants save a lot of money and hence their kids are going to best schools getting best degrees 3) are mannerless, e.g., dont give enogh tips in restaurent, to barber, taxi driver etc. 4) To much of complaints, be it in restaurent, credit card contract, cell phone contract.. 5) Mostly talk negative about america, dont support americas foreign policy 6) Crowding their schools i should say, i think some of the points above are really valid.
