A Blocked Account is a must-have, and it is an inevitable part of student life for any international student who wants to study in Germany. A Blocked Account, often known as a "Sperrkonto," is a unique type of bank account in which a student may deposit money but won't be able to access it until they arrive in Germany. To withdraw your money, you must first come to Germany, provide proof of residence, and open a German bank account to accept monthly deposits.
