At Cornell, about 30 spots are available to exchange students each semester. I applied to take one of the spots and was selected. The school has a full-time employee working with exchange program so everything runs very smooth. I chose to come to Mexico because I was a two year full-time volunteer in Mexico when I was an Undergradute and I always wanted to return and learn about the business side of Latin America.
Other Johnson students went to China, London, Spain, Austrailia, South Africa, Chile, France, just to name a few. The majority go in the Spring because of job search concerns in the Fall. Although I was hesitant about giving up a semester at the Johnson School I figured that I couldn't pass up an opportunity like this. If a full semester abroad is not your cup of tea then there are plenty of international trips to go on - I was fortunate enough to go on the Japan/Korea tip at the end of May.
