I like what Susan Waldau said: "(Studying abroad) may be no more expensive than studying on campus."
Both of my daughters went to school "out of state" at Arizona State University and studied abroad. The cost was the SAME as going to ASU on campus and paying for housing. The only additional cost was the FLIGHT. My oldest daughter minored in Spanish and studied abroad in Spain. She took 6 units in Barcelona and 6 units in Seville. She was gone for 12 weeks. My younger daughter studied abroad in New Zealand. She took 6 units on the "Filmography and Economic Impact of Lord of the Rings." She was gone for 4 weeks. Seriously, my younger daughter toured scenic film locations of "Lord of the Rings" in beautiful New Zealand for a month... It wasn't school. It was a vacation for my kid.
Both daughters truly benefitting from the Study Abroad experience. Highly recommend if the costs are right. As Susan Waldau states: "Adding a semester abroad into the mix may not be that much more overall."
