The suspect in the Boulder, Colo., attack highlights a type of immigrant who has been largely absent from the heated political messaging on immigration: a person who arrives in the United States legally, on a tourist or other temporary visa, and remains after their permission to stay has lapsed.

Mohamed Sabry Soliman, an Egyptian national accused of carrying out the attack in Colorado, entered on a tourist visa in August 2022 that would have allowed him to remain in the country for six months once he presented his passport to a U.S. Customs and Border Protection official at an airport on arrival. Only later did he apply for asylum.
