My husband is in law school at Cornell. There is a small but vibrant frum community there (although it’s mostly made up of undergrads, a handful of grad students, and a handful of families who live and work in Ithaca). He got in with a degree and top grades from Swarthmore, where there is no frum community (he went there before he became frum).
Cornell Law School, so far, has been very accommodating for us. The ten-day writing competition to get onto law review overlapped with Shavuos last year, so they allowed the frum students to start and end later than the others.
