Your Oregon employer will withhold OR income tax, so use your Oregon address. If you are a student, and your parents claim you as a dependent, Your "official" state of residence is the state your parents live in. At tax time, you might need to file a non-resident OR return and a resident tax return for the state your parents live in. If and when you move back to your "home" state, if you get a job in that state, then of course you would use your home state address on any W-4 for a job in your home state.
