I think there are restaurants and amusement parks in the North Woods of Wisconsin that have used this visa. I was fishing in Minocqua a few years back and the waiters at one local restaurant were all Polish. It seemed there were no teens in town; most service personnel were either Eastern European or retired locals.
All of the beach areas on the East Coast do this too. Bring a bunch in from Eastern Europe who somewhat speak English and put them up in an off the beach low rent hotel. Cheaper and less hassle than hiring locals teens just for the summer. They still hire locals, but the J-1’s kept the wages down to a reasonable level.
