I was originally wary about study abroad, but after talking to the staff on the phone, I was sold on going. TEAN's orientation was extremely helpful in getting used to life in Thailand, and helped the students in my group bond before starting classes. We also stayed in a village for a few days along with the rest of our classmates at Chiang Mai University, a really incredible way to experience Thai culture firsthand. The classes were rigorous but interesting, and further contributed to our understanding of the country we were living in. Thai language class was especially helpful in navigating everyday life. Along the way, TEAN staff was ready to help out with any questions we had or just to meet up for a meal. Living with a Thai roommate in a (beautiful) dorm was one of my favorite parts of the program.
In Vietnam, we each had our own apartment with a bathroom in the same building, and took classes at a local private university. While we didn't have any local students in our building or classes, the international club eagerly welcomed us and helped us to make our closest friends. The in-country staff, Chris, worked close to our apartment and would often have dinner with us. As a travel agent by profession, he was able to help us out with navigating the city, the country, and the region.
While most students stayed in Thailand the entire semester, I think having the opportunity to experience two cultures was a unique and worthwhile challenge, and I would encourage any curious and adventurous people to do it. (And, of course, the food was amazing in both countries.)
