Universities in Berlin to take German Classes at?

Hello,

I live in Berlin and am wondering where I can go to a college/university to take some classes in German. My German right now is very basic, just been using Rosetta Stone thus far.

Thanks in advance for the help.

Also any advice on Student vs Work visas would be great.

Why are you looking for a Uni? Search for language schools.

Indeed. It's language schools. Classes at Unis are for their students (and even then the entry requirements are often competitive, you don't just get on one as of right because you are a student there).
