U.S. airports are entering a new era of heightened security screening, and for many international travelers, that means a lot more than just pulling out a passport.

A new customs and border policy that took effect on December 26 has expanded the federal government’s ability to collect biometric information from non-U.S. citizens entering or leaving the country. The change is part of a broader push by the Trump administration to tighten immigration controls.

Under the new system, travelers passing through U.S. airports will now have their faces scanned and photographed as part of routine screening. Those images will be matched against existing government records and stored for up to 75 years, according to a Metro report. 

In some situations, border officials can now go even further. The Department of Homeland Security has the authority to request additional biometric data from non-citizens, including fingerprints and even DNA. This represents a significant expansion of what customs agents are legally allowed to collect at ports of entry.

One of the biggest changes is that the rule no longer makes exceptions for age. Previously, children under 14 and adults over 79 were generally exempt from biometric data collection. Those exceptions have now been removed, meaning travelers of any age could be subject to these screenings.

The government says the new rules are designed to streamline enforcement and discourage abuse of the immigration system. In its newsroom release, the administration said the policy is intended to “deter the filing of frivolous claims and provide operational consistency.” It also added that biometrics will “generally” not be taken unless someone is in “removal proceedings” and has a pending case with the Executive Office for Immigration Review.

The expanded use of biometric technology has raised red flags among civil rights advocates. A 2024 report from the U.S. Commission on Civil Rights found that facial recognition software was more likely to misidentify Black people and other ethnic minorities.

This policy shift comes as part of a larger series of travel and immigration changes rolled out by the Trump administration. The cost of the ESTA — the electronic authorization required for travelers from visa-waiver countries — was recently raised. At the same time, five new countries were added to a travel ban set to take effect on January 1, 2026.

And biometric scans aren’t the only thing border officials may be checking. New vetting proposals would require travelers to provide up to five years of social media history, along with phone numbers, email addresses and even the names of family members.

In a proposal filed by U.S. Customs and Border Protection, social media accounts would become a mandatory part of applying for an ESTA. The agency cited Donald Trump’s Executive Order 14161, which aims to “protect citizens from aliens who intend to commit terrorist attacks, threaten our national security, espouse hateful ideology, or otherwise exploit the immigration laws for malevolent purposes.”

If approved, the proposal would require travelers from 42 countries to submit to much more invasive probes into their personal information when visiting the U.S.
