The White House has ordered the U.S. embassy to temporarily stop arranging new student visa appointments as the Trump administration is committed to expanding social media screenings for applicants, a series of restrictions on international students.

Secretary of State Marco Rubio instructed diplomatic posts not to add any dates to students and forex visas to prepare for an expanded review and to remove any undeserved dates from the calendar. If the student has arranged a visa interview, he can still move on.

The pause will continue until the next few days “until further guidance is issued.”

According to the cable, the State Council is preparing for “expanding the required social media screening and review” and all student visa applicants can undergo social media checks. The cable said this additional screening would have a "significant impact" on the actions of the embassy and consuls and suspend necessary new appointments.

The memorandum was first reported by Politico.

CBS News has contacted the State Department and the White House to comment on the new policy.

International students who want to study in the United States are usually required to schedule interviews at the U.S. embassy or consulate, usually in their home country, as part of the visa application process. Waiting times vary widely: Most embassies, student visa interview appointments can be booked for less than two months, although some diplomatic positions have longer waiting times.

Last month, the Department of Homeland Security (DHS) said it would screen some visa applicants, including those seeking student visas, to learn about its “anti-Semitic activities on social media and physical harassment by Jews.”

Screenings are part of a wider control measure for international students, some of whom meet the impetus of the court system.

Last week, DHS Tell Harvard University It can no longer recruit international students, fighting for months between the government and the Ivy League schools. Homeland Security Secretary Kristi Noem said the government “puts Harvard to promote violence, anti-Semitism and coordination with the Chinese Communist Party on its campus,” but Harvard said the move was illegal. Judge Stopped the policy quickly.

The government is trying to expel a few students based on their pro-Palestinian activism - some of whom have green cards, including Mohsen Mahdawi and Mahmoud Khalil of Columbia University, some of which allow laws to revoke their visas if they constitute "adverse foreign policy consequences." Lawyers believe that the revocation of these visas violates students' First Amendment rights, although the government says it has the right to do so. Some students, including Mahdawi, have been released on bail.

Lawyer says Trump administration Try to end Legal status For thousands of other international students, many of them seem to be targeted Secondary legal violations. Federal judges have Stopped this effort.
