The Congress on Friday expressed concern over the American Immigration Lawyers Association's claim that out of the 327 visa revocation cases of international students collected by it so far, 50% are Indians, and asked whether External Affairs Minister S Jaishankar will take up the issue with his US counterpart. Congress general secretary Jairam Ramesh shared on X a press statement issued on Thursday by the American Immigration Lawyers Association, and said it is "cause for concern to us in India".
