Admission to the IEC does not guarantee admission to the University at Stony Brook. Students who wish to pursue their academic studies at the university must apply directly to the Office of Undergraduate Admissions or to the Graduate School and must be academically eligible. However, the IEC does work closely with the Office of Admissions to assist students in the application process when applying to Stony Brook.

Stony Brook University requires a minimum TOEFL score of 80 iBT (213 CBT) for admission. However, students who successfully complete the advanced level of the IEC program and are academically eligible for undergraduate admission may apply to Stony Brook without having to take the TOEFL exam.
