SIT gave me the best experience possible. While this is not the program for those who would like to move more independently, I found that highly structured time followed by a month free for research was actually very beneficial to my experience. I was very impressed with the academic aspects, and the visits that we did taught me so much more about Argentina than I would've known had I just been visiting. I was consistently impressed by our coordinators, who devoted themselves to ensuring that the program was good and genuinely cared about us. They were attentive and thoughtful and always available. My homestay was a better experience than I had even anticipated, and I found that my host family taught me just as much about the materials we were learning as the professors did.
Overall, I would rate SIT Argentina: Social Movements and Human Rights very strongly. If you are looking for an in-depth, impactful experience that will truly teach you about both the country you're studying in and your own culture, I would recommend this program.
