For the Butler IFSA program in Peru it is mandatory to work with an NGO. The program normally sets students up with a hand-on activity working with women who do domestic work. You can also find other more internship-style opportunities on your own. I wanted to learn about indigenous rights and culture so I found an NGO myself that focused on these issue. I got really valuable experience working in their office and speaking/writing in Spanish. I also got to travel with them to one of their film festival conferences in another city, which was one of the highlights of my experience.
