DENIED BEFORE REACHING U.S. INSPECTION
International airlines check whether U.S.-bound passengers appear to have the required travel documents before boarding. A traveler can therefore be stopped at the foreign airport even before reaching a CBP port of entry.
CBP’s Carrier Liaison Program trains international air carriers concerning U.S. entry requirements, document validity, fraudulent documents and improperly documented travelers.
CBP also operates a Regional Carrier Liaison Group that provides participating carriers with real-time advice concerning entry requirements and document validity.
An airline refusing boarding is not necessarily making the final legal decision that the traveler is inadmissible. The immediate issue may instead be whether the carrier is permitted to transport the person to the United States.
Ordinary admission inspection is conducted by CBP at a U.S. port of entry or at a foreign CBP preclearance facility. An airline check-in agent generally does not replace that CBP inspection.
A traveler refused transportation should therefore determine whether the problem came from the airline’s document review, an ESTA problem, a visa revocation, or a government vetting response.
A visa appearing unexpired in the passport does not necessarily mean it remains valid for travel. A visa can have been revoked or otherwise rendered invalid without the traveler having a new stamp placed over the visa foil.
A Visa Waiver Program traveler generally must have valid ESTA authorization before boarding a participating carrier for U.S. travel under the VWP.
Under APIS vetting procedures, a carrier can receive a government “not-cleared” instruction for a passenger requiring additional security analysis. That instruction has different significance from an ordinary airline conclusion that the traveler lacks required documents.
Not necessarily. If the traveler never reached CBP inspection, an airline refusal to transport the passenger is not automatically the same event as a formal CBP refusal of admission.
Not before identifying the underlying problem. A government document or vetting issue may affect another carrier as well.
Yes. CBP’s Carrier Liaison Program provides real-time document and entry-requirement assistance to international carriers.
These government materials describe the carrier-document, APIS, ESTA and visa rules discussed on this page.
The correct solution depends on whether the problem was an invalid document, ESTA, visa revocation, APIS vetting or an airline-specific requirement.
