US investigates Harvard, Stanford & 7 other universities over J-1 visa fraud

President Donald Trump's administration is investigating nine US universities, including Harvard, Yale, Stanford and others, over alleged J-1 exchange visitor visa fraud. The visa category allows noncitizens to study and conduct research in US temporarily. The universities are "using these visas way too much", undermining wages for American graduate students and researchers, VP JD Vance said.
