Students who temporarily are in financial need due to the Corona crisis, find financial support by The Federal Ministry of Education and Research (Bundesministerium für Bildung und Forschung BMBF).
100 million Euros are divided by the German Studentenwerk (Deutsches Studentenwerk DSW). The individual Studentenwerk will distribute the support on students of regional universities.
E.g. maximum 500€ can be granted for maximum 3 months.
