For all Extended Learning degree programs, "foreign students" include those who hold U.S. visas as students, exchange visitors, or in other nonimmigrant classifications. You must submit academic records from foreign institutions. The original foreign transcript must be on file and if they are not written in English, they must be accompanied by certified English translations. In addition, all foreign transcripts must be evaluated by one of the eight approved CSUSM foreign transcript evaluation agencies.
