Can I manage the second year of my studies without a blocked account if I find part-time jobs in Germany?

No, you cannot skip the blocked account for your second year in Germany, even if you plan to work part-time. German student visa rules require proof of sufficient funds for each year of study, and the blocked account is the standard accepted method.

Part-time work can help with living expenses, but it does not replace the need to show mandatory financial proof for your visa or residence permit renewal. You must continue to demonstrate funds - typically through a blocked account - for every year of your studies.
