According to page 54 of the 2004-2005 USC Catalogue:

The University of Southern California affirms the practice of accreditation of American post-secondary academic institutions by the six regional accreditation agencies: the Middle States Association of Colleges and Schools, the North Central Association of Colleges and Schools, the New England Association of Schools and Colleges, the Northwest Association for Schools and Colleges, the Southern Association of Schools and Colleges, and the Western Association of Schools and Colleges. Acceptance of course work and/or degrees completed by undergraduate and graduate students applying to the University of Southern California will be based on accreditation by these six agencies. Certain graduate schools, seminaries, conservatories and professional institutions of national renown that are not accredited by a regional agency may be considered for graduate transfer work by the Articulation Office in consultation with the USC department or professional school to which the student is applying.

In addition, USC strongly believes that degree-granting institutions should be reviewed by the regional agency that governs the geographical area in which the institution or its branches are operating and issuing degrees. USC will not guarantee acceptance of course work or degrees taken at institutions not accredited by the regional agency for the area where the institution or branch is located.

Acceptance and/or degrees from post-secondary institutions overseas will be based on the recognition and approval of the college or university as a degree-granting institution by the Ministry of Education with the respective country.
