Normative time to degree for the Ph.D. is five years. Maximum time to degree for the Ph.D. is seven years. During this time, a minimum of 66 units of combined coursework, independent study, and research, must be completed.

Throughout their entire program of study, students must be registered at either UCI or SDSU. Students who have completed coursework requirements must enroll in the appropriate research units at the home campus of their primary faculty advisor. International students should consult with International Centers at both SDSU and UCI to ensure that appropriate paperwork is on file with both offices. Full-time registration is required to maintain immigration status.

Requests for leaves of absence or in-absentia registration must be reviewed and approved by both campuses. An approved leave of absence cannot be longer than one year, three quarters, or two semesters.
