The United States is directing its U.S. diplomatic missions abroad to resume student visa applications, but is requiring applicants to make their social media profiles public for vetting purposes, a senior State Department official said on Wednesday.

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.

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.
