He wants to be an exchange student in high school, but instead of doing it through a program like AFS or Rotary, he's arranging things himself and put up a website to find a family. With programs you don't get so much say as to where you go, often not even the country, much less the state. Since he's a techie, i'd imagine he wants to end up in Silicon Valley or near by. Seems like a smart tactic to me. That said, he probably needs a follow up page or something for folks who are serious about hosting, which includes what it's like and need to host him as a high school exchange student.
