<p>The NC Constitution states that “the benefits of the University of North Carolina and other public institutions of higher education, as far as praticable, be extended to the people of the State free of expense.” This provision is why tuition is lower in NC than in other states. As a resident and taxpayer in NC, I don’t have any problem with the 18% limit on undergraduate OOS students because our universities are intended to benefit NC citizens. The limit does not apply do graduate students and the graduate student body at UNC has a high % of OOS students.</p>
