South Korean students warned over posts amid US crackdown

President Donald Trump's administration is raising scrutiny over the social media posts of South Korean students in the United States or who plan to study there, the students and agencies that support them said.

That has triggered concerns for parents of students studying or planning to study in the United States. South Korean students are the third-largest among international students in the US, behind those from India and China.

The US administration ordered its missions abroad to stop scheduling new appointments for student and exchange visitor visa applicants as the State Department prepared to expand social media vetting of foreign students, according to an internal cable seen by Reuters on Tuesday.

The Trump administration has sought to ramp up deportations and revoke student visas as part of wide-ranging efforts to meet its hardline immigration agenda.

"My clients, parents are calling me constantly today to figure out what is going on," said Park Hyuntae, head of Worldnet US Overseas Edu Center, an agency in Seoul that assists South Korean students.
