Major technology companies and foreign governments are rushing to respond after President Donald Trump late Friday announced plans to impose a $100,000 annual fee on H-1B visas , threatening to upend the program that underpins America's technology workforce.

The Trump administration said the fee would apply per worker, per year, potentially dealing a massive blow to companies — primarily in the technology and finance sectors — that rely heavily on highly skilled immigrants, particularly from India and China.

The announcement sent shockwaves through corporate America. Amazon's immigration team advised its H-1B and H-4 visa holders to remain in the U.S. and for those overseas to return before 12:01 a.m. ET on Sept. 21, according to internal messages viewed by CNBC.
