The Trump administration has proposed a new rule that would impose a four-year limit on the duration of stay for foreign students in the United States.

The rule targets visas for foreign students, cultural exchange programs, and foreign media, and comes as part of the administration's ongoing efforts to regulate student visas more strictly.

Under the current system, foreign students who hold an F visa can stay in the country for the duration of their studies.

However, the proposed rule would establish a fixed admission period of 'up to the duration of the program they are participating in, not to exceed a 4-year period.' This means that students would be required to leave the United States after completing their program, with some exceptions.

The new rule also sets a time limit for foreign media representatives, allowing them to stay in the country for up to 240 days, extendable for the same length.

According to a Department of Homeland Security spokesperson, the proposed rule aims to address past Administrations' leniency towards foreign students and other visa holders.

The spokesperson claims that this has posed safety risks and disadvantaged U.S. citizens, while also costing taxpayer dollars.

The new rule is intended to limit the amount of time certain visa holders are allowed to remain in the country, thereby easing the burden on the federal government.

In recent months, the State Department has strengthened its rules and procedures for vetting student visas.

Over 6,000 student visas have been revoked this year due to individuals staying beyond their visa expiration dates or breaking the law.

This is nearly four times the number of revocations during the same period last year.

The State Department has also instructed its embassies and consulates to scrutinize student visa applicants for any signs of hostility towards the U.S. culture, government, institutions, or founding principles.
