Copyright: DEBBIE/GeographThe college, in Grantham, is part of the University of Evansville in Indiana.
A statement on the college website says all students should make plans to return to the US by 18 March where they will be able to continue their courses online.
It states there are no known cases of COVID-19 at the college, and that the decision is based on the safety and well-being of students.
Christopher M. Pietruszkiewicz, president of the University of Evansville, said: "Over the course of the last few weeks, we have implemented a variety of measures to prevent the spread of COVID-19. We have determined that further proactive steps are necessary. We understand that these measures will undoubtedly cause inconvenience and disruption, but the inconvenience and disruption are outweighed by the risks of inaction by the university."
