Each department and College sets their own foreign language requirements. Make sure to do this at the beginning of your program, so that you have time to prepare. The earlier you know what is required the more options you will have.
Questions to ask: Does my degree program require a Reading Proficiency in a Foreign Language? (If yes, which languages can be used to satisfy the requirement? Some programs will require a certain language) How many foreign languages are required for your program? (While most departments require only one there are some that require proficiency in two).
