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.
