Indian software professionals in US

I guess this means programmers, and I find this hard to believe, but here's the quote: "About 26-28 per cent of software professionals working in the United States are from Andra Pradesh." Andra Pradesh is a state or province in India. I hear that the Indians are well known for cheap and competent programming, and also that Microsoft and others are taking up the opportunity of using their services, but I find the 26-28% figure astounding none-the-less.
