Foreign nationals who seek visas to study in the United States will have to make social media posts public to be scrutinized for hostility toward the U.S.

Rubio paused visa interviews last month while the State Department created rules for the social media screening. The U.S. State Department is rolling out sweeping new rules for vetting student visa applicants using their social media presence, according to POLITICO.

The US State Department told embassies and consulates they must vet student visa applicants for “hostile attitudes towards our citizens, culture, government, institutions, or founding principles” but said they may resume appointments that were paused in late May.
