Can a Medium of Instruction (MOI) Certificate Waive the IELTS Requirement in the USA?

In the USA, only a few universities consider a Medium of Instruction (MOI) certificate as a substitute for IELTS or TOEFL. Most universities still prefer or require a standardized English language test. While you may find some institutions that accept MOI, it is not very common, and relying only on MOI can significantly limit your options. To keep a wider range of universities available, it is generally better to take IELTS or TOEFL.
