Texas Republicans made it tough on illegals if they wanted to attend one of our colleges. The other 38 states allow those illegals to have the same benefit as a legal American student. There is a fed law regarding illegals...one law they keep...that allows illegals to have in state tuition without questioning their nationality.
So Texas took the bull by the horns...and controlled it.
You don't need a law that specifically excludes illegals when you don't even let them enter the school.
BTW, those rules that require a visa? That's about a federally issued student visa. It doesn't give you instate tuition. It gives you a right to enter a specific school for a specific time at OUT OF STATE TUITION RATES.
