Only bona fide residents of Oregon who meet the residency guidelines outlined in the Residency Standards and Procedures will be assessed resident tuition rates. 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.

A few key considerations* in determining classification as a resident for tuition purposes:

  1. Establishment of a domicile and predominant physical presence in Oregon for a period of 12 months or more prior to the beginning of the term in which resident status is sought.
  2. Financial dependence on an Oregon resident or financial independence.
  3. Primary purpose for being in Oregon other than to obtain an education.
  4. Nature and source of financial resources.
  5. Various other indicia of residency (e.g., ownership of Oregon living quarters, permanent Oregon employment, payment of Oregon income taxes)

* Key considerations are for quick reference purposes only. For a complete explanation of these factors, refer to the rules in the Residency Standards and Residency Guide and Procedures.
