CBP Facial Biometrics: What It Means for Visa Overstays

You landed at a U.S. airport, looked into a camera for two seconds, and walked through. That quick scan is now part of a system that has checked over one billion travelers — and flagged more than 600,000 people who stayed in the United States past their authorized period. U.S. Customs and Border Protection (CBP) announced this milestone on October 5, 2026, and the numbers carry real consequences for anyone with an uncertain immigration status.

How the system works — and how it catches overstays

Since 2018, CBP has used facial biometrics at all U.S. airports with international arrivals and at exit from 66 airports. The technology matches your face against passport and visa photos with over 98 percent accuracy. When you leave the country, the system records your departure. If no departure is recorded after your authorized stay ends, CBP flags you as an overstay. That flag can affect future visa applications, green card petitions, and even trigger removal proceedings. Beyond overstays, the system has identified more than 2,300 impostors — people using someone else's travel documents.

The program is expanding fast. The One Big Beautiful Bill Act, signed in July 2025, gave CBP $673 million specifically to roll out biometric entry-exit systems at all U.S. ports of entry. Facial biometrics are already active at all pedestrian lanes on both the southwest and northern land borders. CBP is now deploying the same technology to vehicle lanes at select locations and testing pedestrian exit scanning at a southwest border port. Seaports are covered too — 42 ports use facial biometrics, including 25 cruise ship debarkation points.

For U.S. citizens, photos are deleted within 12 hours of the scan. For non-citizens, the image is stored in the DHS Biometric Identity Management System as a permanent record of your entry or exit. If you do not want to participate in facial biometrics, you can tell a CBP officer and request a manual document check — that option remains available under current rules.

What to do

• Check your I-94 record (the official record of your authorized stay) at i94.cbp.dhs.gov to confirm your departure was recorded correctly after any international trip.
• If you believe you were flagged as an overstay by mistake — for example, your departure was not recorded — consult an immigration lawyer before your next visa application or entry to the U.S.
• If you are currently in overstay status, lawyers recommend speaking with an immigration attorney before traveling internationally, since leaving the U.S. can trigger a multi-year bar on reentry depending on how long you overstayed.
• If you prefer not to use facial biometrics at a port of entry, tell the CBP officer before the scan and ask for a manual document check — this is your right under current CBP policy.
