Well-known Chinese news site Sina recently reported that, based on a recent study, in 2016 there were 25,486 Chinese visitors in the United States who overstayed without proper permission. Among these people, 7,545 were Chinese students on expired visas. Among students from all foreign countries, this number is the highest. The country that ranked number two is India (3,014); South Korea is number three (2,068). The statistics were based on an analysis of overstay visa data that the Department of Homeland Security released. The same study also showed that the type of visa that suffered the largest share of the overstaying population was the student visa, reaching 42,493 in 2016. That’s 2.74 percent of all student visa holders. The consequences of overstaying without proper permission can be quite severe. It may lead to a minimum three-year ban (typically it is a 10-year ban) from entering the U.S. One could also be banned from the right to status adjustments or to obtaining a different type of U.S. visa anywhere else except in the country of origin.
