For those of you who were asking about weather and safety:
1) Winter is really cold. Las week we have freezing temperatures (-30ºC/-25ºF). It is colder than any other city with major universities. The wind is awful and if you go out during a wind chill advisory it is almost certain you will have skin cuts As soon as you arrive in Chicago you need go to a store and buy winter clothes (and I am not joking). In any event, as you will be studying as hell you will not have much time to go outside and be cold
2) As for the NY bar preparation the BAR/BRI courses start in June and you should have your last exam on March 31. So you will be fine. Be sure to bring transcripts in English from your universities as they are required by the NY Board of Examiners as also letters from those universities. If you enter the NY Bar web page you will be able to see everything they will require and believe me, it is not a walk in the park.
3) Safety is definitely an issue. If you are planning to live in Hyde Park the only really good option is Regent´s Park. Buses stop in the door (# 172 for the university and # 6 downtown, youve got the Metra one block away). The advice we are always given is not to go out walking during the night even within the campus. Last November a student from the university was shot just a few meters outside the campus Hyde Park is a bubble within the south Chicago area. So, as long as you live in Regents Park, do not walk randomly during dark hours, and do not do stupid tings you should be fine. If you do not live in Regents Park the issue is that when you go downtown no bus will leave you near you department and thus you will have to walk (please dont as it is dangerous) or take a cab from downtown (cause you will not find them easily in Hyde Park which will cost you around $20).
Hope this helps.
