Here's the deal, federal law says that you cannot give preference to illegals ~ or even legal residence for any purpose.
Perry and the Texas legislature are perfectly willing to violate federal immigration law where it serves to discourage illegal immigrants.
Pretty obvious how this is going to end ~ it will take armed force ~ probably first against Texas elements, and then Mexican elements.
Texas residents pay $50 per credit hour. It’s a nice rate but it’s not a scholarship.
