Change ausbildung visa to student visa .

    My son went to Germany with a student visa for a studienkolleg course and he changed to an ausbildung (apprenticeship) visa later. Now he is trying for a bachelor's degree course and If he gets admission to a college/university, can he change his ausbildung visa into a student visa and join to university without completing that ausbildung?

A critical question is if he finished the Studeinkolleg since it is a prerequisite for people to do a bachelor if they don't have the level of the German Abitur needed for acceptance. An Ausbilduing (vocational training) is not a substitute. He has to finish either the Studienkolleg - or usually do 2 years of university at home before getting into a bachelor in Germany. This would be 2 years of a bachelor or maybe an associated degree would qualify.

And language skills are still a major factor. The vast majority of bachelors are taught on a C1 level German. Most of the exceptions, the ones offered in English are at private universities, which tend to charge 8 to 10 thousand euros/semester for tuition.

Most masters are taught in English even in public universities where while tuition-free for EU-students, they are not necessarily so for non-EU one's. It totally depends on the program. Cost can range from 0 to 8,000 euros/semester. And yes that is public not private universities. While one might find an exception, the idea that a non-EU student can get a tuition-free degree instructed in  English is rare.
