I don't know. Are you an international student? Were you parents citizens or green card holder when they were here? Which UW campus is this? Most importantly, how does this particular school operate in terms of monitoring in state/out of state status? Some schools don't care at all; some are vigilant. You do need to look on the website as to what their actual rules are so that if you find that they do not enforce them, you know where you are vulnerable. Schools have gone on crusades to beat out the OOS kids "passing" as in states, and that is the risk you take if you manage to slip by the registrar initially.
