As student from abroad you have the basic right to submit an application for housing subsidy.
• proof of your study
• passport with your valid residence permit
• your rental agreement or contract
• receipts showing payment of rent (amount paid, beneficiary of the payment, payee)
• evidence of income e.g. maintenance payments, scholarships (official translation into German).
Any decision concerning housing subsidy payments, as well as amounts, are made on a case-by-case basis. More information you can get from the social counseling service of the Studentenwerk or from the local housing offices operated by the local district authorities.
