The American Friends Service Committee - US/Mexico Border Program (USMBP) is a human rights advocacy organization that was established to support immigrant rights and concerns by documenting human and civil rights abuses by law enforcement agencies in and around communities on the San Diego County-Mexico border. The records mostly encompass the organizational and administrative activities directed by Roberto Martinez, director from 1982-2003. The collection contains incoming and outgoing correspondence, field reports and studies, and meeting minutes, with similar materials in records for the parallel project, the Immigration Law Enforcement Monitoring Project (ILEMP). The main components of the records are abuse complaint case files and legal case documents compiled from individuals by the USMBP, the Centro de Asuntos Migratorios (CAM), the Chicano Federation of San Diego County, and the Coalition for Law and Justice. Additionally, the papers contain conference and seminar materials, subject files, brochures, published writings, and other materials supporting projects and organizations involved with AFSC and Roberto Martinez.

Since 1940, the American Friends Service Committee - San Diego (AFSC-SD) has worked closely with migrant workers and promoted rural and urban development in Mexico. Focusing on improving the living and working conditions of migrant workers and strengthening their political voice, the AFSC-SD has historically played a principal role in Mexicano activism in the US-Mexcio border region of California.
