Students who would like to enroll in courses at another institution while maintaining their student status at USC require permission from OIS through the Permission to Attend Another Institution (PTAAI) letter. In order to register at another institution, students must be first registered full-time at USC for the same term (except for summer semesters).
The PTAAI letter is only a verification of a student’s full-time student status at USC under the USC I-20 authorization. It is not an approval to transfer unit credit, subject credit or for major substitution.
USC students who wish to transfer courses from another institution must consult their academic advisor and the USC Office of Articulation BEFORE registering for the courses.
There is a 4 business day processing time for PTAAI letters.
To request a PTAAI letter, please submit the appropriate form for your immigration status:
