Secure and Fast Entry at the Border Act of 2003 or the SAFE Border Act of 2003 - Amends the Immigration and Nationality Act to make the Port Passenger Accelerated Service System (PortPASS) permanent.

Provides for minimum two-year entry approvals under the Secure Electronic Network for Travelers Rapid Inspection (SENTRI) program along the United States-Mexico border. Precludes a person convicted of a felony or under active criminal investigation from program participation.

Expresses the sense of Congress that: (1) the Department of Homeland Security must ensure the permanence of PortPASS in its transition from the Department of Justice to the Department; (2) all land PortPASS programs should utilize interoperable technology to offer participants increased commuter lane access; (3) the Secretary of Homeland Security should increase SENTRI program staff, training, and resources; and (4) the Secretary should create a pre-inspection low-risk commuter lane for pedestrian land border crossers.
