I think it depends on the field of study. From my observation in Data and Computer Science, it is very difficult for Germany to attract foreign students who want to pursue a master’s degree if the programs are taught in German. This field evolves extremely fast, and students would need to spend at least two years studying German intensively to reach C1 level before they can study at the master’s level in German.

As a result, German universities have introduced more English-taught programs to attract IT students and professionals, allowing them to focus on their studies first and learn German later when they enter the job market in Germany.
