Clem, I have hoseted several international exchange students in my time, so here is some advice. Your profile says that you are 17, so I'm assuming that you are still in high school. What you need to do is find an exchange program that works in Germany to bring students to the US. Rotary & CCI International are a couple that I know of right off the top of my head, but YOU have to start the process oin your end (passports, J-1 Visa, application, etc.). Once your visa & application are approved, the program will place you with a family here in the US, hopefully in a location close to your choosing. I have had students with CCI for the past few years, and they have very high standards. Good luck.
