"What most of my friends are doing to get out of OOS tuition is that Texas State law mandates that you must either own or rent property for a minimum of a year before you are considered a resident. (This means you need to live off-campus at either an off campus dorm or an apartment; make sure your name is also on the lease.) So what they’ll do is pick up a part-time job for the first year, then the remaining 3 years you are at school you’ll be paying in-state tuition. "
