He is from Rheine, Germany. we learned about this because my son attended a meeting about it at school, and he came home and asked us about it. the staff has been very helpful and profressional so far. They do a lot of screening on both sides, and the students have to pass an English test, and get lots of references.
If you go online, I think you will be able to fins the agency. It is called International . If you have two rooms, maybe you can host more than one student so that they can keep each other company!
