Indians are NOT ON WELFARE> as a rule, the percentage is too low to accurately measure. On the whole, they are goal driven and educated. They learn English and often learn it before entering the US. Compare that with Mexican immigrants who speak as little as possible. As an elementary school teacher in California, I can attest to that.
Your numbers are wrong. There are approx. 3 million Indians in the USA. Now, how can 2,700,000 be illegal?? That would surely set off alarms, don't you think???
Besides, if you checked the numbers, 70% of all illegal aliens in the USA are from Mexico.
