Just a report on this.
I applied and got confirmation in about 2 weeks. I made an appointment for a week later at EWR. I showed up a half hour before my appointment and they took us right in. They asked us for a passport and licence. They did not ask for mail for proof of address. (I guess a licence is good enough) They then scanned my fingers and asked a few simple questions. The whole thing took 10 minutes.
