When US President Donald Trump signed an executive order last Friday to add a $100,000 (£74,000) fee for applications for H-1B visas, a programme for skilled foreign workers, Abhishek Singh immediately worried he would have to relocate.
Mr Singh, a software engineering manager based in the Seattle area, knew that his employer - a US startup - would not be in a position to pay the fee on top of his current salary.
Mr Singh, who has been working in the US for ten years - the last seven of them on a H-1B visa - breathed a slight sigh of relief when the White House clarified on Saturday that for now, the fee only applies to future applicants.
But his worries are an indication of the potentially far-reaching consequences of the change, as it creates new burdens for businesses, especially startups, with what some say could be significant fallout for innovation and economic growth.

The H-1B programme is often associated with the giants of the US tech sector. Amazon tops the list of beneficiaries, with more than 10,000 H-1B visas approved in the first half of 2025. Microsoft, Meta, Apple and Google each secured more than 4,000 visas through the programme through June.
None of the companies responded to requests for comment.
But while just 30 employers - mainly big tech companies - dominate the programme, accounting for an estimated 40% of the new H-1B visas available, it is not just the behemoths that are poised to be affected by Trump's executive order.
Startups, as well as smaller firms beyond tech, also employ workers through H-1B visas. For them, a six-figure fee per applicant could be crippling.
If you're a startup with new technology, and you've got some venture capital money but you're worried about burning through it too quickly, this could kill you, said John Skrentny, a professor at the University of California, San Diego who studies STEM workforce development.
Beyond the technology industry, organisations in industries such as education and healthcare, both of which employ foreign skilled workers through the H-1B programme, are also grappling with what the six-figure fee might mean.
There's no way that we can afford $100,000, said Karen Brady, the chief executive at Ryther, a behavioural health nonprofit based in Seattle. In terms of future hiring, we won't be doing any more H-1B visas.
The behavioural health sector has been grappling with a workforce shortage amid a spike in need since the pandemic, Ms Brady said. Hiring employees through the H-1B programme has helped address the crisis, she said.
In a research note, Atakan Bakiskan, an economist at the investment bank Berenberg, lowered his estimate for US growth from 2% at the start of the year to 1.5%, saying the $100,000 H-1B fee is part of the Trump administration's broader anti-growth policymaking.
Despite the reprieve, Mr Singh said he was still considering leaving his startup if he could find a job in his home country of India, or elsewhere - Canada, Japan, South Korea - worried the administration will continue to harden policies against immigrants.
