The Trump administration said it would suspend an immigration program for multiple tech firms, including Microsoft Corp., alleging widespread abuse of a worker visa system. “There has been no company in the United States, unfortunately, that has abused this system more than Microsoft,” Vice President JD Vance said Thursday during a briefing in Washington. Labor Secretary Keith Sonderling said other companies that would be suspended from the Permanent Labor Certification Program included Cognizant Technology Solutions Corp., Infosys Ltd., Tata, Wipro Ltd., HCL Technologies Ltd., and Capgemini SE. He said there were multiple active federal investigations ongoing into the matter.
