Oregon State University (OSU) operates on a quarter system with four intake periods: Fall (September), Winter (January), Spring (March), and Summer (June). Application deadlines vary by program and student type. For undergraduate applicants, the priority deadline for Fall is February 1, while regular decisions are accepted until June 1. Graduate programs often have earlier deadlines, typically 6-9 months before the start term.
International students should apply at least 3-4 months in advance to allow for visa processing. Deadlines for scholarships or assistantships may differ. Always verify specific dates on OSU’s official website or with the admissions office.
