We got our FP done @ Newark, NJ. The scheduled time was 9:00 AM EST but just to beat the crowd we (my wife and me) went there @ 6:30 AM. Please don't call us nuts as, believe it or not, there were already 20 people ahead of us. Ours was code 3.
We were just asked to produce the license and the original FP notice, although we had taken quite a lot of stuff like EAD, 485 notice, etc with us. For people who don't remember their SSN, please take your SSN cards also.
At the 1st FP counter, they took the the FP of the right hand index finger, digital signature, and digital photo. At the 2nd FP counter, they took FP of all the 10 fingers. After doing the FP someone was called to do the QA of the finger-prints, after which they stamped our original FP notice and gave it back to us. Our FP was completed by 8:35 AM.
Parking:
I parked in the parking lot which is on the junction of Commerce St and Mulberry Drive. The parking attendant comes only @ 7:00 but u can park earlier also. The rates are $8 for 1 hour, $10 for 2 hours and $12 for 3 hours. For people who are coming by train, it's only 7-8 minutes walk from the Newark Penn Station. For people coming after 8:00-8:30, I would advise them to take the train as getting a parking might be difficult.
Cracked/Dry fingers:
I would advise such people to start using "Corn Huskers Lotion", available @ any Pharmacy, at least 2-3 weeks before the scheduled FP date. That's the lotion that the officials apply on your hands before taking FP. I had read somewhere on this forum earlier about that lotion also.
People With Kids:
I would advise them to take the strollers for sure. The wait might be long, depending on the time you go.
