I note the integration with both graduation and major requirements seems very good many places these days. In fact, my S24’s planned major, Classics, has a capstone requirement, and one of the ways to fill it is with (approved) study abroad.
Obviously there are other ways too (senior honors thesis, directed research, or a special project in a 4000-level seminar), so he’ll be fine. But I can see lots of colleges are trying to make study abroad a viable option for as many kids in as many majors as possible.
