Work / Can I become a teacher in Poland? Can I go to college there? [7]

So I used to live in Poland and i speak the language but I've been living in the US for 6 years now and Im going to finish high school in a couple years and are interested in going to collage to Poland to become a teacher either a normal teacher or just a English teacher. I would like to go to the university in Krakow so I can be close to my family which is the main reason I want to move back there.What would I have to do to be eligible to be a teacher in Poland?What classes would I have to take? Could I be a full time teacher or should I only teach English? I would want to take the classes in English if that's possible.
