The Secure Electronic Network for Travelers Rapid Inspection (SENTRI) is a U.S. Customs and Border Protection (CBP) program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States. Participants may enter the United States by using dedicated primary lanes into the United States at Southern land border ports.

Travelers must be pre-approved for the SENTRI program. All applicants undergo a rigorous background check and in-person interview before enrollment
