At least some international experience is becoming commonplace for college students, from those that go to other countries just for a short trip in the summer to those who do their entire studies abroad and even stay in those countries after they graduate. Another important way that American college students gain international experience is through the presence on their campuses of students from abroad.
Nowadays, because of demographic stagnation in many states as a consequence of flat and even negative high school graduation rates, more and more institutions of higher education are relying on enrollment of international students to make up for those U.S. students who are not enrolling. Additionally, because those international students pay higher rates of tuition, public colleges and universities find them as a good source of revenue.
