Once a year, Verein der Freunde und Förderer der HSBA offers part-scholarships for study-abroad periods (from 2014 mostly study trips). Furthermore, HSBA students can apply for partial financial assistance at any time in the event of hardship. The part-scholarships will be and sent by e-mail to the HSBA students (generally January/February).
Even if you are not entitled to BaföG funding in Germany, there is a chance that you may qualify for study-abroad funding. It's worth a try! You can find more information and a BaföG calculator here.
