You’re applying/graduating this year? Or working on a list for next year?
In terms of a true safety (including being guaranteed to meet budget), Truman State would come in under 30K with auto-merit, and they have an undergrad business program. Very solid public honors LAC which would be far more in demand if it were in a more popular location (vs. rural Missouri). They also have D2 volleyball if that would be a fit.
Mount Holyoke takes a high proportion of international students and does give some aid. Full-need-met isn’t guaranteed for internationals, but you seem like a strong enough applicant to possibly get in with enough merit and/or need-based aid to get to your budget. The financial piece makes it a reach for affordability, though. They have D3 volleyball if that’s of interest.
Babson could be worth a look. They have a full-tuition “global scholars” award that could be a possibility, although I’m sure it’s quite competitive. The school is business-oriented and well-known for its entrepreneurship focus; students can also cross-register at Brandeis and Wellesley. They have D3 volleyball as well.
Agree that with your German fluency, studying in Germany could be a good and affordable option.
