TTPRADARIAH's Global Entry setup is three locations, not one
George Bush Intercontinental doesn't have a single Global Entry office. There are three separate enrollment points serving IAH, and going to the wrong one means a wasted trip through the terminal or downtown.
| Location | Details |
|---|---|
| Terminal E arrivals level (3870 North Terminal Road) | Public walk-up counter, no appointment needed. Open 8 a.m. to 4 p.m., Monday to Friday. |
| Terminal E secure area | Walk-up window, but you need a boarding pass to reach it. Open 9 a.m. to 3:30 p.m., Monday to Friday. |
| Houston Public Library (500 McKinney St., downtown Houston) | A satellite enrollment office away from the airport entirely. |
The Terminal E arrivals-level counter is the one most travelers want. It sits in the public part of the terminal, outside security, and takes walk-ins during its posted hours with no appointment on the books. The secure-area desk works if you're already past security for an outbound flight, but you can't reach it without a boarding pass, so it isn't an option if you're heading to the airport just for the enrollment interview.
Skip the enrollment center: Enrollment on Arrival
If your Global Entry application already shows conditional approval on globalentry.gov, you can skip the enrollment center entirely. IAH takes part in CBP's Enrollment on Arrival program, which lets conditionally approved applicants finish the interview during normal arrival processing on an international flight into Houston.
Look for signage in IAH's international arrivals hall pointing to a dedicated Global Entry Enrollment booth, staffed by a CBP officer. You go through the standard inspection process, and the officer handles the enrollment interview as part of it, no separate appointment required.
Conditional approval still has to come first. Enrollment on Arrival replaces the standalone interview booking, not the application and background check that happen online before you travel.
Getting an appointment slot at IAH
If Enrollment on Arrival doesn't apply to you, IAH's interview calendar works the same way every other enrollment center's does. A batch of new slots opens nationwide on the first Monday of each month at 9 a.m. local time, and more slots appear throughout the month as other applicants cancel or reschedule.
As of September 11, 2026, IAH's own interview wait was under a week. Del Rio and El Paso, two other Texas enrollment centers, were running roughly two-month backlogs by comparison: a same-day scan of 114 enrollment centers nationwide put Del Rio's next opening 60 days out and El Paso's 53 days out, among the longest waits found in that scan.
There's no waitlist and no way to request an earlier date directly. The practical move is to book whatever slot the calendar shows, even weeks out, then keep checking back for cancellations that open up sooner. You can track current wait times across every enrollment center, compare IAH against every location TTPRadar monitors, or set up free browser alerts that flag new openings without you having to refresh the calendar yourself.
Construction at IAH: what actually affects your visit
IAH has had construction running for years, but the two current projects sit on opposite sides of the airport. Terminal E, home to both the Global Entry enrollment center and Enrollment on Arrival processing, was substantially complete on its $1.46 billion redevelopment by early 2026. International airlines moved into the rebuilt terminal that February, and airport officials say parking access there hasn't changed.
The active work as of this writing is at Terminal B, where United's terminal modernization is set to finish in fall 2026. That's a different terminal from Global Entry processing, so it won't add time to an enrollment center visit or an Enrollment on Arrival landing at Terminal E.
