What a fantastic guide. ^
I have a query relating to the immigration hall set up. Entering the US through ORD, my recollection of the set up is slightly different to what is described in this guide.
As you approach immigration, descending by staircase or escalator there are two halls. One straight ahead and to the right; the other behind and to the left. Each hall is a mirror set up of the other, such that Visitors in both cases are directed to the desks farthest away from the foot of the entrance stairs. Perhaps this has changed in the last few months and apologies if so. I have been caught out by this before and faced the indignity of being turned away at the INS desk. I blamed that one on a false sense of familiarity and the last minute glass of pinot on approach.
