Shares of Indian IT firms including Infosys, TCS, Tech Mahindra and Wipro fell up to 2% on Wednesday, after the Trump administration announced changes to the H-1B visa selection process. The US Department of Homeland Security (DHS) has replaced the random lottery system of H-1B visa with a weighted selection process. The new method gives more importance to highly skilled and well-paid workers. It will come into effect from February 27, 2026.
