The sector, which earns about 57 of its total revenue from the US market, has long gained from US work visa programmes and the outsourcing of software and business services a contentious issue for many Americans who have lost jobs to cheaper workers in India.
India was by far the largest beneficiary of H-1B visas last year, accounting for 71 of approved beneficiaries, while China was a distant second at 11.7, according to US government data.
Trumps move to reshape the H-1B programme will force IT firms with clients such as Apple, JPMorgan Chase, Walmart, Microsoft, Meta and Google to pause onshore rotations, accelerate offshore delivery and ramp up hiring of US citizens and green card holders, experts said.
