The US government on Monday reportedly accused the top Indian IT firms like TCS and Infosys of indulging in 'unfair' practices to get the lion's share of H-1B visas. The US has said that the companies do this by putting extra tickets in the lottery system. Notably, Tata Consultancy Services, Infosys, and Cognizant were the top three recipients of H-1B visas in 2016.
