US Entry Tips for International Students: What Harvard's Advisory Means and How to Prepare in 2025

In 2025, 1.2 million international students will still choose to study in the US. But as Harvard advises international students to expect increased Customs and Border Protection (CBP) scrutiny at some US airports, entry guidelines are changing. During a July 3 webinar, which drew in over 500 students, Harvard shared helpful preparation tips for social media screenings, device inspections, and legal documentation, and suggested avoiding Boston Logan in favor of JFK, O'Hare, or LAX. As SEVP revocation claims loom and temporary injunctions are in place, students heading to US campuses need informed, actionable guidance to ensure smooth US entry.

Why Harvard Issued a Travel Advisory to International Students? 

In a July 3 webinar attended by over 500 students, Harvard officials warned that Boston Logan International Airport has seen increased scrutiny from Customs and Border Protection (CBP). There have been reports of prolonged interrogation or secondary inspections of students, particularly those with STEM backgrounds, and those from China or Iran. Harvard suggested flying to these airports because they facilitate more efficient travel for foreign visitors. 

• JFK (New York)

• O'Hare (Chicago)

• LAX (Los Angeles)

Choose the Right US Airport and Prepare for CBP Screening 

Not all ports of entry are the same. While Boston Logan may be geographically closer to Harvard, it is currently under tighter scrutiny. Choosing JFK, O’Hare, or LAX may help reduce delays. Students should be ready for extensive inspections at any airport. Harvard advises international students to bring all necessary academic records, including their SEVIS receipt, CV, admission letter, and I-20/DS-2019. Additionally, they should confirm that electronic devices are available and unlocked.

What to Expect from Social Media Check and Device Inspection?

Officers at the consulate and CBP have increased digital vetting. Students who post about politically sensitive topics, like Palestine or criticism of the US, may have their visas denied or take longer to process. Fascinatingly, not being active online can also be interpreted as suspicious. Here are some useful tips you can use to maintain a good digital presence: 

• Maintain a clean but consistent online profile.

• Avoid controversial content before travel.

• Don’t reset your phone or wipe it. CBP can ask for access, and sudden deletion can be a red flag.

Status of SEVP Revocation

Citing national security concerns, the Department of Homeland Security suggested in June 2025 that Harvard's SEVP (Student and Exchange Visitor Program) access be revoked. New F-1 or J-1 visas could not have been issued as a result. Visa processing has resumed, though, and Harvard's SEVP is still in effect. Since this legal dispute may change, students should continue to follow developments via the university's official channels.

It's important to keep in mind that Harvard's recommendations are not intended to cause panic but rather to equip international students with proactive, wise travel planning. By carefully selecting entry points, preparing your online presence, and keeping all required documentation on hand, you can drastically reduce stress and delays.
