Folks, in #7, OP had made a decision. The deadline for submission is 11/15, and the common advice is to not wait until the last minute so as to avoid IT glitches that could make the app late. Why is everyone asking the OP to second guess the decision? I am sure we all want to be helpful but in the context of the question, the fact that OP is an expat and cannot visit, are we helping?
Personally, I would not want my kid to ED to any school without visiting first (in part because the social environment was important to him and he wanted to be active in the community.). Each of these schools has a different “dominant culture,” and the OP sounds like he may be on the edge/outside of that at all of these. That doesn’t mean no friends and no social life – at most schools, most kids find their peeps.
This applicant seems to want to ED, and if he’s strong applicant, that’s good strategy…
I am guessing (but I could be wrong) based on the question about first time airfare that OP may not visit ANY college prior to matriculation.
