Houston George Bush Intercontinental Airportimmigration & passport control wait time

How CBP measures this. The wait shown is how long arriving passengers took to clear Passport Control at IAH in the most recent reported hour, averaged across processed flights. Visitors (non-US citizens) typically wait longer than US citizens and Global Entry members.

Numbers update hourly and reflect completed hours, so they read as a recent history rather than a live queue. Plan connections with the peak max in mind, not the average.
