Options for expedited crossings for qualified travelers:

• SENTRI Program
  Secure Electronic Network for Travelers Rapid Inspection (SENTRI) is a U.S. Customs and Border Protection program that allows expedited clearance for pre-approved, low-risk travelers upon arrival in the United States. There are no age or nationality requirements for SENTRI. Participants may enter the United States by using the dedicated primary vehicle and pedestrian lanes into the United States at southern land border ports only. SENTRI cardholders may not use SENTRI vehicle lanes without first registering the vehicle bring driven.

U.S. citizens, U.S. lawful permanent residents and citizens of Mexico and certain other countries are eligible for Global Entry membership. It is not limited to the southern land border ports. Global Entry cardholders may not use SENTRI vehicle lanes without first registering the vehicle bring driven with the SENTRI program.
