As a foreign student in Germany, one has a 120-full-days or 240-part-days work limit during the year.
I have also noticed that different laws about foreigners not only depend on one's city but are moreover even open to interpretation by the foreigner's office, that is one can observe different behaviors for equal/similar cases.
After an inquiry I was told that the main point behind this law was for the student to focus on his studies and the important bit was that the student made progress in his studies.
My question now is, assuming the study process doesn't get harmed, would there be any consequences if one exceeded this limit? For instance if you surpass it to 130-full-days, what would happen?
