Entry into the U.S. requires authority from the USDOT. As a Mexico-domiciled carrier, you have two options: (1) application for authority for operations limited to the U.S. commercial zones, which requires a Certificate of Registration (and otherwise known as OP-2 authority), or (2) application for authority for operations beyond the U.S. commercial zones into the continental U.S., which requires a Provisional Operating Authority (and otherwise known as OP-1(MX) authority). Each type of authority has an application process and specific steps the carrier must comply with before receiving approval to make pickups and/or deliveries in the U.S. However, regardless of the type of authority the carrier obtains, no Mexico-domiciled carrier may make conduct point-to-point operations within the U.S.
