For generations of Indian tech workers, the H-1B visa has been a golden ticket, turning ambitious engineers from Hyderabad and Bengaluru into Silicon Valley professionals, as it transformed Indian IT firms into global powerhouses.Now, a Trump administration proposal to sharply raise the minimum salaries required to qualify for the programme threatens to close that door to the United States, redirecting Indian talent towards Europe, Australia, New Zealand and beyond instead.Under the new proposal, an entry-level software engineer in San Francisco would need to earn US$162,000 a year to qualify for the visa, according to Bloomberg – nearly 30 per cent higher than today’s threshold. In Dallas, the floor would rise to US$113,000; in New York, US$132,000.For the Indian IT heavyweights – TCS, Infosys and their peers – whose entire business model was built on deploying engineers at client sites across America, the implications are profound.People exchange US dollar and Indian rupee banknotes at a foreign exchange office in Amritsar, India.
