I did study abroad the summer after my freshman year, which I think was a good time since I wasn’t too busy with things or wrapped up in a career path. I do think this can be pretty early, especially if you’re in a program that caters to your major, but otherwise I’d recommend it. I see study abroad often aimed at or discussed among upperclassmen (juniors and seniors). Since they’re further in their studies, I think this makes sense, but you also get pretty busy and wrapped up in school/work by these years. Overall, I think the timing depends on a person and his or her major/ time.
