Application deadlines for universities in the United States vary significantly by institution and program. Many private universities typically have deadlines around February or March, while public universities often set deadlines in November or December. For example, the University of California has a November deadline. Washington State University’s specific deadlines can vary by department, and it is recommended to check the university's website for the most accurate information. A priority deadline for applications is often January 31, but it is advisable to apply earlier if possible. Students currently in high school or those completing adult education programs need to plan ahead to ensure they meet these deadlines, especially if they are working towards finishing their high school credits. Additionally, once enrolled, students usually register for classes about two-thirds of the way through the preceding semester, with procedures differing by university.
