Financial Support for students struggeling due to COVID-19:
Students having financial problems caused by COVID-19 situation, can apply for a interest-free student loan offered by KfW. International students can apply as of June 1, 2020 and the first payment could reach you after July 1, 2020. The special loan conditions for international students are only temporary available until March 31, 2021.
