Trump administration’s proposal of stopping extension of H1B visas would impact some 5,00,000 to 7,50,000 highly skilled Indian technology professionals, academicians and research scholars in US and result in their moving back to India.Move to end of extension of H-1B visas would be “bad policy” said US Chamber of Commerce. Chamber said this is contrary to the goals of a merit-based immigration system.This visa programme offers temporary US visas that allow companies to hire highly skilled foreign professionals working in areas with shortages of qualified American workers. But since taking office last January, President Donald Trump has been cracking down on the scheme.
