I know foreign kids come over here and work in summer camps. So that means there are jobs available.
My daughter tried to get the same type of job with the same company in Yellowstone for much the same reasons. Unlike my sister's experience, they had absolutely zero flexibility in modifying their contract dates to meet their seasonal employees semester schedules. Zero.
Which may explain why they import foreign students rather than hiring Americans willing to work but unwilling to make it a career.
Ditto Door county in Wisconsin. Packed with Czech, Polish, Hungarian kids. Meanwhile all you hear is moans from Milwaukee about how there’s no summer jobs for “youth”.
