FLIGHT CONNECTIONS AFTER CBP INSPECTION
International travelers generally must complete CBP processing at the first U.S. port of entry before continuing to another flight. Secondary inspection can take longer than primary inspection, so a traveler with a close connection can miss the onward flight while CBP completes the inspection.
CBP states that travelers arriving from abroad must clear CBP at the first U.S. port of entry before proceeding onward.
A departing connecting flight does not require CBP to stop an otherwise necessary inspection before the officer has completed it.
Secondary inspection can involve document review, immigration questions, database checks, customs issues or other inquiries. There is no single published maximum number of minutes that applies to every secondary inspection.
Current CBP guidance states that international travelers entering from overseas generally retrieve checked baggage for CBP processing and recheck it with the airline for the next flight.
CBP has begun implementing International Remote Baggage Screening on selected routes. Where that process applies, qualifying connecting passengers can continue without retrieving and rechecking bags unless CBP refers the baggage for further inspection.
Do not assume the remote-baggage procedure applies to every airport, airline or international route.
Travelers who complete CBP preclearance at a participating foreign airport generally arrive in the United States as precleared passengers and can proceed directly to the connecting flight or destination without repeating ordinary CBP inspection upon U.S. arrival.
If the traveler misses the connection, ask the airline about rebooking, available flights and baggage handling. CBP controls the border-inspection process; the airline’s ticket and rebooking rules govern the carrier’s response to the missed flight.
If repeated secondary inspection causes recurring travel problems, preserve dates, ports, duration and questions asked. DHS TRIP may be relevant where a traveler is repeatedly referred for additional screening because of potentially inaccurate government information.
A flight departure does not eliminate CBP’s responsibility to resolve the inspection before permitting the traveler to proceed.
That remains the general CBP guidance for international arrivals connecting onward, although selected routes using CBP International Remote Baggage Screening can operate differently.
Air preclearance generally allows the traveler to bypass ordinary CBP inspection after landing in the United States and proceed to the connecting flight or destination.
These government materials provide the principal U.S. transit, visa and CBP inspection rules discussed on this page.
A single missed connection may be an airline and timing problem, while repeated CBP referrals can justify reviewing the inspection record and possible traveler-redress options.
