US Preclearance


General Aviation

CBP officers in Shannon are using new mobile equipment to enable biometrics to be carried out at the aircraft, therefore not requiring passengers to come into the CBP facility in the terminal.

The time to conduct a US Preclearance has been reduced to less than half the time it takes to refuel the aircraft.

Please allow 24 hours’ notice for private flights.

Military Preclearance

US Alliance together with Homeland Security & US Government are working on extending the unique ability to pre-clear corporate jet passengers, to clearing US troops on their way back home. This service will save time on arrival for the troops after a hard tour and also open several more airport options to crew and passengers as the flight then becomes a “Domestic Flight“ after departing Shannon.

We need your support on getting this service approved.

Preclearance from KSA

As the Kingdom of Saudi Arabia (KSA) prepares to enter into the CBP program for signatory carriers, US Alliance plan to open our KSA trip support office in Jeddah and later in Riyadh. Planned to open in 2019, our KSA offices will offer assistance to corporate jet customers travelling to the United States with pre-clearance services from KSA via our FBO in Shannon. This means US Alliance trip support team will prepare the entire pre-clearance trip from KSA with a quick tech stop in EINN. CBP officers will pre-clear the aircraft and passengers while the aircraft is refuelled. In less than 45 minutes from touch down, your aircraft will continue to the United States as a domestic flight.
