Panic, confusion and then a hasty White House climbdown - it was a weekend of whiplash for hundreds of thousands of Indians on H-1B visas.

On Friday, US President Donald Trump stunned the tech world by announcing an up to 50-fold hike in the cost of skilled worker permits - to $100,000. Chaos followed: Silicon Valley firms urged staff not to travel outside the country, overseas workers scrambled for flights, and immigration lawyers worked overtime to decode the order.

By Saturday, the White House sought to calm the storm, clarifying that the fee applied only to new applicants and was a one-off. Yet, the long-standing H-1B programme - criticised for undercutting American workers but praised for attracting global talent - still faces an uncertain future.

Even with the tweak, the policy effectively shutters the H-1B pipeline that, for three decades, powered the American dream for millions of Indians and, more importantly, supplied the lifeblood of talent to US industries.

That pipeline reshaped both countries. For India, the H-1B became a vehicle of aspiration: small-town coders turned dollar earners, families vaulted into the middle class, and entire industries - from airlines to real estate - catered to a new class of globe-trotting Indians.

For the US, it meant an infusion of talent that filled labs, classrooms, hospitals and start-ups. Today, Indian-origin executives run Google, Microsoft and IBM, and Indian doctors make up nearly 6% of the US physician workforce.

Experts say pay data shows why Trump's new $100,000 fee is unworkable. In 2023, the median salary for new H-1B employees was $94,000, compared with $129,000 for those already in the system. Since the fee targets new hires, most won't even earn enough to cover it, say experts.

However, the impact of the visa fee hike remains uncertain. Immigration lawyers expect Trump's move to face legal challenges soon. As the dust settles, the H-1B shake-up looks less like a tax on foreign workers and more like a stress test for US companies - and the economy. H-1B visa holders and their families contribute roughly $86bn annually to the US economy, including $24bn in federal payroll taxes and $11bn in state and local taxes.

How companies respond will determine whether the US continues to lead in innovation and talent - or cedes ground to more welcoming economies.
