The TOEFL (or IELTS) test is required for all students whose native language is not English. The requirement will be waived if you already have a U.S. college degree. The test scores expire after two years. If the University receives the official scores before they expire, they will accept them regardless of the actual enrollment date. (For example, if a student's TOEFL score expires in May 2018 and he or she submits an application in December 2017, the university will accept the score even though it will be expired when the student starts classes in August 2018.)
Can I have the TOEFL waived?
