"Infosys, TCS accounted for only 8.8% of total H1B visas"

"All Indian IT companies cumulatively account for less than 20% of the total approved H1B visas although Indian nationals get about 71% of the H1B visas,” Nasscom said. It added that this is a testimony to the high skill levels of India-origin professionals. The annual number of Indian IT specialists working on temporary visas for Indian IT service companies is about 0.009% of the 158-million-member US workforce, it said."

I wonder since this data is public, how come different stats are concluded ?
