<p>If you go to a state school as an OOS student but your parents move into the state after your freshman or sophomore year, do you then get to pay in-state tuition for your remaining years?</p>
<p>Most of the time, yes. I say most of the time, because there are schools/states that have a time period before you are regarded as a resident. Michigan is an example.</p>
<p>This is something you want to check on with each individual school -- as cptofthehouse posted, there is a waiting time at many schools (usually in the neighborhood of a year). Some schools will not change the residency from non-resident to resident at all during the undergraduate years -- whatever you enter as, you continue as.</p>
