Petition Process and Deadlines

Steps in the Petitioning Process

  • Attend a residency orientation to obtain detailed information regarding Colorado residency requirements, the petitioning process, petitioning deadlines, and to obtain a “Petition for In-State Tuition Classification.”
  • Complete the “Petition for In-State Tuition Classification” and attach all required documentation. The burden of proof to provide clear and convincing evidence of eligibility for Colorado residency is the responsibility of the petitioner.
  • Petitions must be submitted no later than the deadline date.
  • Completed petitions that include all required documentation will be typically be reviewed within 4-6 weeks.
  • Students will receive the decision through CSU email.  Parent petitioners will receive the decision through the email address provided on the petition.
  • To avoid late payment charges, continue to pay the amount due on your University student account by the due dates. If you are determined to be a Colorado resident, your non-resident tuition/fees will be adjusted to the Colorado resident rate. You will be reimbursed if you paid more tuition/fees than are due as a resident.

Any student who provides false information to avoid paying non-resident tuition may be subject to legal and/or disciplinary action.

Petition Review and Decision Process

  • Completed petitions that include all required documentation will be reviewed and petitioners will be notified of the decision by email typically within 4-6 weeks after the completed petition is submitted.
  • If additional information is required, the additional information must be submitted within two weeks of the request unless special arrangements are made with the Tuition Classification Office.
  • Decisions made by the Tuition Classification Officer may be appealed to the University’s Residency Appeals Committee.
    • Petitioners who want to appeal the decision must contact Office of Financial Aid no later than the deadline provided in the decision letter.
    • The decision of the Residency Appeals Committee is the final University determination for that semester.

Petition Deadlines

  • Submit completed petitions to Office of Financial Aid no later than the published deadline date for the semester for which you are petitioning.
  • Mailed petitions must be postmarked by the deadline date.
  • Petitions will not be accepted after the published deadline date.
    • If you are a new student admitted to CSU no earlier than 30 days before the posted petition deadline or after the posted petition deadline, please contact our office as soon as possible to inquire about the petition process for your circumstances.
  • Incomplete petitions will not be accepted and/or reviewed and your tuition classification and tuition assessment will remain non-resident for that term.
  • Residency statutes do not permit retroactive tuition re-classification.
