I have hosted, and I have been a foreign exchange student. I went to France my senior yr of high school. We have hosted a girl from Germany and a boy from Spain. Oh, and I am an area coordinator for an Exchange Program. I have helped a girl go to Australia, one to Germany. And interview potential host families, help place students with them, and facilitate school applications for the students. It is definitely work, but VERY rewarding. My kids learn a lot about getting along.Actually, I have learned a lot. My German student and I have just begun discussing some issues that made her stay turn a bit stressful...but we definitely are very fond of each other.
If you decide to do it, and have any questions or would like advice, I am always willing to talk about my experiences and ideas.
