If you come from abroad and wish to study or work in Germany, you must prove that you have sufficient funds to finance your living and studies in order to obtain a visa.
For general purposes, this can be proved with a blocked account into which a minimum amount of money has to be paid. The blocked account is called a blocked account because it is not managed by the account holder himself, but by a trustee. The account balance is therefore “blocked” and the account holder can only dispose of a previously defined amount each month.
Currently, the monthly amount required for living in Germany is 853€. The annual amount – that is 10,236€ – is now paid into the blocked account and blocked until entry. After entry, 853€ is transferred monthly to a current account, which you can use as you like.
