Foreign students in the United States - numbering in the hundreds of thousands - will have to leave the country if their classes are all taught online this autumn or if they transfer to another school with in-person instruction, a government agency has said.
It is not immediately clear how many student visa holders will be affected by the move, but foreign students are a key source of revenue for many US universities as they often pay full tuition.
China ranked first among countries of origin for international students in the US with nearly 370,000 during the 2018-2019 academic year, according to data published by the Institute of International Education.
