Actually, on the cheap end of the spectrum, Whitefish High School has an international exchange program where kids live with local families. They also are supportive of the mountain's ski team, working to accommodate the extensive travel the team has to do. Ideally, of course, the host family would be supportive of that as well. I'm not up on the current team-high school arrangement. I believe there is online coursework to supplement day time training for higher level racers, but the race program is scalable in that regard. We are, at the moment, relatively safe when it come to Covid, but who knows by the time school resumes? This alternative would produce a more "normal" exchange program for her high school years, with skiing thrown in. If there's any interest, I can get links for you to talk to about it.
