You can go at any time; however, most programs require that you have at least sophomore standing.
We want you to stay on campus long enough to feel a part of Ball State. But after that, you are free to explore the world.
And remember, you can study abroad more than once. Consider testing the waters early on with a short summer field study, then going back for a semesterlong or yearlong program.
Also, many overseas transcripts take one to two months to be returned to the U.S. As a result, it is unlikely you will be able to study abroad during your last undergraduate semester.
