In state /out of state tuition fees

<p>I'm looking at couple of colleges in Texas and they have quite a difference in Instate and out of state tuition fees. Let's say you get admission and you start going to school, for first year you will pay out of state tuition, do you pay instate tuition the following year as you may become resident of Texas after living there for a year, you will have postal address etc. The same rule will apply to any state.</p>
