The Trump administration readied a fresh immigration crackdown that experts said could permanently damage the economy.
White House officials said they would cancel the visas of 200,000 asylum seekers, potentially representing the single largest mass visa revocation in US history.
The Trump administration also proposed charging more than $100,000 for visas granted to skilled workers, despite bipartisan support for a program that has helped attract an array of talent to the US; an earlier effort ran into legal challenges.
Academic studies have also backed up the success of the H-1B visa program: A recent paper showed the visas lifted incomes for foreigners and locals alike, with gains accumulating along the supply chain.
