If a U.S. Citizen from Ohio comes to Texas, they will not pay the lower in-state tuition rate. If a criminal invader comes to Texas, they pay the lower in-state tuition rate.
Can you fathom the problem with this situation?
But the criminal invader has paid taxes to Texas in the form of sales tax for at least three years. So that makes it OK in the minds of some.
BTW, everyone has to pay their own tuition, it's not a freebie paid for by Texas.
