I think the bigger problem with teenagers is that in Israel, Charedi society is much more black and white. Either you do it their way, or you are out.
I know of American Yeshivish families that just couldn’t find a proper place in Israel. They were to yeshivish for Chardal, too modern for Charedi society etc.
Rules are much more rigid and have zero flexibility. I think most American Jews aren’t used to that. Teenagers especially.
