Okay so every option I have looked at for extending my stay here with my family has turned out to be a bust.

i was told there was a possibility of me getting a student visa/permit if I took a german course (and I know that I need to learn more german). Does anyone know of any schools/courses that qualify for me to apply for a student permit? such as how many hours a week I would have to take? where I could take it? etc. any advice is greatly appreciated!
