I and my wife got our passports stamped in Newark this morning. It was a very smooth process. We arrived at 8:20 AM submitted the documents mentioned in the 485 approval notice and waited for our turn in the waiting room (lots of seating available). We were called at about 9:30 and done in about 10 minutes. My observation is that if you get there between 10 and 11 AM it could be even faster. Thanks for all the postings on this site. I have contributed a few times but was an active visitor. All the best to everyone.
