Since requirements differ greatly by program and are subject to change every year, you must check OHSU's main Undergraduate Admissions webpage for international students as well as the pages pertaining to your particular program to find out the precise requirements. On the other hand, foreign applicants typically need proof of English proficiency (such as TOEFL or IELTS scores), a high school certificate comparable to a U.S. high school degree, and possibly specialized academic preparation for their program of choice.
