The U.S. government has taken significant action against major tech companies including Microsoft, Adobe, and various Indian IT firms by suspending their access to the green card sponsorship program for H-1B visa workers. This crackdown, led by the Trump administration and announced by JD Vance, cites allegations of fraud and abuse within the worker visa program. Consequently, these companies are barred from sponsoring foreign workers for permanent residency, which is expected to create considerable challenges for their operations and staffing. The situation has already led to a notable decline in the stock values of affected firms, including Infosys, as the fallout from this visa suspension escalates.
