Hi, and welcome to the forum.

To get acquainted a bit with Chicago, you may want to start following the Chicago Tribune online Chicago news, sports, photos, video, blogs, Chicago weather, business, travel, tourism, entertainment and jobs -- chicagotribune.com There is also a guide to the Indian community in Chicago that might interest you: Chicago Hindu Temples - Chicago Indian Community Guide

Chicago is a city of neighborhoods, and there are a huge variety of neighborhoods available within the city. Most (but not all) areas are reasonably well served by public transit (bus and the "El" a subway/elevated rail service). The suburbs of Chicago use commuter rail service to get into the city, but many commuters have to drive to the train station. Public transit in the suburbs is minimal to non-existent.

It may be hard to find everything you want in one residential community.
Cheers,
Bev
