US Government Excludes Microsoft from Visa Program
The US government has barred Microsoft from participating in the permanent residency process for foreign workers with H-1B visas, accusing the company of abusing the program. Vice President JD Vance stated that Microsoft laid off 6,000 American employees last year while benefiting from 6,300 H-1B visa holders. The Department of Labor, led by Keith Sonderling, will not accept new permanent residency applications from Microsoft, as well as several consulting firms and Adobe. This action comes weeks before the midterm elections and reflects the Trump administration's broader criticism of the H-1B program, which it claims disadvantages American workers. Microsoft has not yet responded. The move could impact the tech industry's ability to retain skilled foreign talent.
Outlook to Block MSIX Files as Email Attachments
Microsoft has announced that Outlook will begin blocking MSIX file attachments, a move aimed at preventing malicious distribution through email. The change affects both the classic Outlook for Windows and the new Outlook for Windows, as well as other clients like Outlook on the web. Microsoft's decision comes in response to the increasing use of MSIX files in phishing and malware attacks. The block will be implemented in phases, starting with a controlled rollout and then expanding to all users. The company advises users to use alternative secured methods for sharing such files. This technical update is part of Microsoft's broader security enhancements for its email clients.
US suspends Microsoft, Adobe from green card labor program
The U.S. Department of Labor announced the suspension of Microsoft and Adobe from its Permanent Labor Certification program, along with Cognizant, Infosys, Capgemini, Tata, Wipro, and HCL. Secretary Keith Sonderling cited active federal investigations for Microsoft and Adobe, and criticized the companies for allegedly taking jobs from American workers. Vice President JD Vance specifically accused Microsoft of replacing laid-off workers with H-1B visa holders. Microsoft responded by defending its hiring practices, stating that the majority of its U.S. employees are Americans and that most H-1B petitions are for existing employees. The announcement was made during a White House summit on H-1B fraud, coinciding with President Trump honoring several tech CEOs with the National Medal of Science.
