As early as possible. Purchase begins accepting undergraduate and graduate applications in August, just prior to the start of the fall semester and students are encouraged to begin the application process at that time. This will allow students plenty of time to complete the process. Generally we recommend that all international students apply no later than October 1st for spring semester admission (for those programs that accept students in spring) and no later than January 1st for fall semester admission. For specific program application deadlines, please review our International Student Application Instructions .
