Southern Illinois University – Carbondale (SIUC) operates on a rolling admissions basis for most programs, but priority deadlines ensure full consideration. For fall semester intake, the priority deadline is typically March 1, while spring semester applications should be submitted by November 1. Summer session deadlines vary by program.
Graduate programs may have specific deadlines, often earlier than undergraduate dates. International students should apply at least three months prior to the semester start to allow for visa processing. Check SIUC’s official website or contact the admissions office for program-specific deadlines, as some departments enforce earlier cutoffs.
