Studying arts in Korea?

Hello I am Leyla from Germany.I just recently moved back to Germany due to family problems.I was studying level 2 Arts in England before that and had to break off my studies.I had been planing to move seoul for a long time.i want to mostly major in graphic design but Arts is my main goal.I am 18, and I am new to a lot of things , So i am wondering, how can i continue my studies in seoul? Are there any students jobs? And cheap places to live at? What visas would i need etc?Are there any other possible jobs?I learn fast and can read/write hangul and I am learning hangul thanks to a friend, so language wouldnt be such a big problem. I would appriciate if someone could help me out.
Thank you :)
