No Title
kkh,
I went to Newark with courtesy copy on May 30th. There were no questions asked. I got the passport stamped. The total time spent there was one hour and half (reached around 10 and left there at 11.30).
My observation was that if you reach there around 11, it could be done within one hour.
If you are driving, there is a parking lot just behind the INS building.
Good luck.
