If you're a minor - you don't.
If you're over age 18 and under 21, and attending school half-time or more and making satisfactory academic progress, then you can receive support directly. You can appear as a party to a child support case - in fact, you are a necessary party to the case - and request a modification. You can do this either by filing a motion to modify support in your local county circuit court, or as an administrative procedure through the Department of Justice's Child Support Enforcement Division. You can learn more about this process here: http://oregonchildsupport.gov/Pages/Index.aspx
