Tuition Cost

Please review the detailed tuition tables to find current tuition and fees cost. Some programs have different costs.

Oregon Tuition Equity Bill - HB2787

House Bill 2787 provides that certain students are entitled to exemption from nonresident tuition and fees at public universities. In summary, OSU may grant in-state tuition for undocumented students who have attended school in the country for at least five years; studied at an Oregon high school for at least three years; graduated from an Oregon high school; enroll in university no more than three years from graduating from high school; and show intention to become a U.S. citizen or lawful permanent resident. For more on the process, take a look at the Tuition Equity page.

Oregon Residency

Oregon State University carefully reviews the residency status of all students at the time of application using the Residency Standards. Only authorized residency officers may apply and interpret these rules and procedures. No other indication or determination of residency by any other institutional office, department, program, or staff represents the official institutional determination of residency for Oregon State University.

Please visit the undergraduate admissions website to obtain a residency affidavit, learn how to fill one out and to submit it.
