What F-1 students need to re-enter the U.S. after travelling abroad

International students on F-1 visas who travel outside the United States generally need three documents to be allowed back in: a valid passport, a valid visa and a current Form I-20 endorsed for travel, according to U.S. Immigration and Customs Enforcement (ICE). The agency advises students to speak with their designated school official before leaving the country.

The guidance matters as new international enrolment at U.S. colleges and universities continues to fall, with the Institute of International Education (IIE) reporting a 17% drop in first-time international students in fall 2025.

What do F-1 students need to re-enter the United States?

ICE states that F-1 students travelling outside the United States generally need a valid passport, a valid visa and a current Form I-20 endorsed for travel in order to re-enter the country. The agency advises students to check with their designated school official before any international trip.

What if my visa has expired?

Students whose visas have expired may remain in the United States while they maintain valid F-1 status. However, ICE says they generally must obtain a valid visa before they can return from travel abroad.

How many international students are in the United States?

U.S. colleges and universities hosted 1,177,766 international students during the 2024–25 academic year, a 5% increase on the previous year, according to the IIE's 2025 Open Doors report. First-time enrolment moved the other way, falling 7% to 277,118.

IIE's Fall 2025 Snapshot showed the decline continuing, with participating colleges and universities reporting a 17% decrease in new international student enrolment in fall 2025.

Where can students get help?

At Texas Christian University (TCU) in Fort Worth, the International Services Office (ISO) runs orientation programmes for incoming international students and exchange visitors covering immigration regulations, cultural adjustment and life in the United States. The office also offers workshops, information sessions, individual appointments and walk-in advising on maintaining status and international travel.

Pamela Guerrero, a coordinator in the ISO, said international students are "not just adjusting to a new campus but a new country, customs and culture," and urged students to make use of the resources available, including student organisations and extracurriculars.

What this means for travellers

Students on F-1 visas who plan to travel abroad should confirm their passport and visa are valid and that their Form I-20 has been endorsed for travel before leaving the United States. ICE advises checking with the designated school official first, particularly if a visa has expired.
