A crackdown on H-1B visas is reportedly impacting the US jobs market, with some companies becoming less willing to hire foreign graduates. The effects of the crackdown appear to be widespread, potentially affecting various industries, including tech and healthcare, although the extent of the impact is unclear. Some reports suggest significant declines in immigrant employment and changes to hiring practices, while others mention specific actions by companies and institutions, such as pausing H-1B visa hiring or revamping job titles.
