What Is U.S. Preclearance?
U.S. Customs and Border Protection (CBP) operates inside select foreign airports, performing the same inspections you’d face on U.S. arrival—before departure. You get the benefits of faster arrivals and fewer missed connections.
Official info: CBP Preclearance.

How Preclearance Works (Step-by-Step)
- Check in and clear local airport security.
- Enter the CBP Preclearance area.
- Complete immigration and customs/agriculture inspection.
- Proceed to your gate and board your U.S. flight; you’ve completed U.S. inspection prior to departure (you remain in the departure country until the flight departs).
On U.S. arrival: You typically skip CBP and head straight to your connection or exit (secondary inspection is possible but uncommon).
Global Entry & Mobile Passport at Preclearance
- Global Entry (GE): Many Preclearance locations offer GE kiosks; GE isn’t required to use Preclearance but often shortens the inspection step.
- Mobile Passport Control (MPC): Availability varies by airport—check your departure airport’s guidance.
- Enrollment on Arrival (EoA): If you’re conditionally approved for GE, you may complete the interview upon U.S. arrival (including some arrivals routed via Preclearance airports).

Why You Should Arrive Early
You must clear both local airport formalities and U.S. Preclearance, and facilities operate on set schedules. Add 30–60 minutes beyond your usual international buffer—more for peak morning banks, holidays, families, or checked bags.
- Check facility hours: Don’t cut it close.
- Have documents ready: Passport, visa/ESTA, and declarations.
- Plan connections wisely: You can often book tighter U.S. connections since you arrive “domestic,” but keep a sensible cushion.
Non-Rev & Airline-Employee Tips
- Earlier flights win: First-bank departures mean shorter queues and more same-day backup options.
- Track loads: If bumped, a precleared arrival can still make the next domestic hop—gold for non-rev connections.
- Pack smart for agriculture: Don’t get delayed over snacks/produce—declare and know the rules.
Preclearance FAQs
Do I still go through CBP when I land in the U.S.?
Generally, no—you pre-cleared abroad. You could be referred to secondary inspection in rare cases.
Is Preclearance the same as Global Entry?
No. Preclearance is a location-based process; Global Entry is a membership that expedites inspection. You don’t need GE to use Preclearance.
Does Preclearance cost extra?
No extra fee to use Preclearance. (Global Entry has its own application fee.)
What if the Preclearance facility is closed when I arrive?
Preclearance facilities have set hours. If they’re closed, you may need to wait until they reopen or rebook; otherwise you’ll face the full CBP process on U.S. arrival. Always check hours in advance.
Is Mobile Passport Control available at Preclearance airports?
CBP has been expanding MPC; availability varies by airport—verify with the airport and CBP before your trip.
