CBP Preclearance refers to a program operated by the U.S. Customs and Border Protection (“CBP”) that allows U.S. bound travelers to complete immigration, customs, and agriculture inspections before departing for the United States, rather than upon arrival at a U.S. Port-of-Entry. This process occurs at designated preclearance locations outside the U.S., typically at foreign airports.

Key Features of CBP Preclearance:
- Efficiency for Travelers: Passengers who clear CBP at a preclearance location are treated as domestic travelers upon arrival in the U.S. allowing them to bypass processing lines and directly proceed to their final destinations.
- Preclearance Locations: CBP operates preclearance facilities in several countries, including Canada, Ireland, the United Arab Emirates, Aruba, Bermuda and others. Airports with preclearance include Toronto Pearson, Dublin Airport, and Abu Dhabi International Airport (AUH).
- Enhanced Security: The program strengthens U.S. border security by screening passengers and their baggage before they board the aircraft, mitigating risks before the flight even departs for the United States.
- Partnerships with Foreign Governments: Preclearance facilities are established through agreements between the U.S. and the host country. These agreements ensure CBP officers can operate under specific rules within the foreign jurisdiction.
- Airlines and Airports Benefits: For airlines, preclearance streamlines operations, especially for hubs in the U.S., as arriving passengers don’t need to manage through customs bottlenecks and can transit to connecting flights much quicker. For airports, preclearance can attract more direct U.S.-bound flights.
CBP is continuously exploring opportunities to expand the preclearance program to additional international locations, aligning with its goal of improving travel efficiency while enhancing national security.
Frequently Asked Questions
What is the CBP Preclearance program?
CBP Preclearance is a U.S. Customs and Border Protection program that allows travelers to complete all U.S. customs, immigration, and agriculture inspection AT THE DEPARTURE AIRPORT abroad — rather than at a U.S. port of entry after arriving. Travelers who clear preclearance exit at the U.S. destination as domestic travelers without needing separate customs or immigration processing.
Which airports have CBP Preclearance?
As of 2026, CBP Preclearance is available at: Canada (9 airports including Toronto Pearson, Vancouver, Montreal), Ireland (Dublin, Shannon), UAE (Abu Dhabi), UK (London Heathrow — select gates), Caribbean & Bermuda (Nassau, Aruba, Bermuda, Freeport), and Jordan (Amman). The current full list is maintained at cbp.gov/travel/preclearance.
Does CBP Preclearance apply to travelers from Vietnam or the Philippines?
Not currently. There are no CBP Preclearance facilities in Vietnam or the Philippines. Travelers from Ho Chi Minh City, Hanoi, or Manila complete standard U.S. customs and immigration processing upon arrival at a U.S. port of entry. However, travelers routing through Abu Dhabi (AUH) may be able to use preclearance at that airport if their connection time is sufficient.
What is the biggest benefit of CBP Preclearance?
The biggest benefit is time savings — particularly for travelers with domestic U.S. connecting flights. Instead of waiting in customs and immigration lines after arriving in the U.S., preclearance travelers can exit immediately and reach connecting flights faster, significantly reducing the risk of missed connections when layover windows are short.
Is CBP expanding the Preclearance program to new locations?
Yes — CBP is continuously exploring opportunities to expand preclearance to additional international locations. Discussions have been reported regarding potential expansion to airports in Japan, South Korea, and other Asia-Pacific countries, though no official announcements have been confirmed as of 2026. Monitor updates at cbp.gov for the latest information.
