The U.S. Department of Homeland Security (DHS) has formalized its authority to create a comprehensive biometric entry-exit system, publishing a final rule that mandates the collection of photographs from all non-U.S. citizens upon both entry and departure. The rule, “Collection of Biometric Data from Aliens Upon Entry to and Departure from the United States” (RIN 1651-AB12), is set to take effect on December 26, 2025.
The rule represents the final legal codification of a system that has been in development for decades, but its text contains several critical changes. The most significant is the removal of language that previously limited biometric collection at departure to “pilot programs” and specific, named ports. The new text authorizes DHS to collect biometrics from departing aliens at “airports, land ports, seaports, or any other authorized point of departure.” This shift effectively grants Customs and Border Protection (CBP) a blanket, permanent authority to deploy facial recognition infrastructure nationwide.
The publication of this final rule signals an end to the “testing” phase of biometric exit. While the Notice of Proposed Rulemaking (NPRM) was first issued nearly five years ago in November 2020, its finalization moves the program from a long-running pilot to permanent, national infrastructure.
The rule legally solidifies the operational reality of existing programs like “Simplified Arrival,” which already use facial recognition for entry at most international airports. The crucial development, however, is the explicit expansion to exit tracking and, most importantly, to land ports and seaports, which have historically lagged in biometric coverage.
For the identity technology industry, this is a massive procurement signal. DHS now has the explicit legal green light to move to full-scale implementation, a process that CBP estimates will take three to five years for full coverage at all commercial ports. This will necessitate a vast build-out of cameras, backend matching software, and data infrastructure at hundreds of land and sea crossings.
While the rule itself is final, DHS is strategically requesting new public comments, due November 26, 2025, only on the “specific collection process” and “costs and benefits” for these newly formalized modalities. This indicates that while the *what* (nationwide biometric exit) is decided, the *how* (the specific technology and process) is the next phase to be refined—a phase that will be defined by industry contracts.
The move builds on CBP’s existing facial recognition infrastructure, which processed over 178 million travelers in 2024, and represents a significant expansion of the agency’s biometric capabilities at U.S. borders.
