I agree with theprof1 on many points. The following are definitely true:
1) The chinuch in most USA seminaries is at least equal to their counterparts in E”Y.
2) It costs a bloody fortune to send your daughter to seminary in E”Y vs. USA
3) If you are a frequent visitor to E”Y, then you see what I see – girls all over town, and boys too. You do run the risk vs. as theprof1 says: seeing them daily at home and watching who they hang out with
4) The idea of girls begging for Shabbos meals – and you have no idea where they end up – is very dangerous, and probably disgusting (including the part of eating into the kolel yungermans tight budget)
5) Chassidish people do have less problems doing shidduchim then the yeshivish crowd – ask any shadchan
But all that doesn’t mean that a girls can not absorb the E”Y kedusha and being “mistapek bemiut” being there. And if you can afford it and it works out for you, the bentsch Hashem.
