I had my Naturalization Interview and my experience is very similar to Luveks;
My appointment time was at 1:00pm, and I reached there about 12:30pm. I put my Appointment Letter in the box and was called at around 3:00pm (long wait..). Once in the officer room, she first asked me to rais my right hand and asked me if I only told the truth and I answered "Yes". Then, I was asked to sit down and she asked me to give her my green card and passport, then verified my name, DOB and Native Country.
Once she verified those, she started to ask me questions from my N-400 application, Those were all from "Yes", "NO" parts. She asked me if I made any trips outside country after application. I said yes since I had a trip to out of country after application in Dec-05/Jan-06. She asked about the citation for traffic violation. I told her it was Speeding Ticket. She did not ask anything after that (no documents were asked).
After that, she gave me 6 questions from standard 100 questions;
1. Who wrote Star Spangled banner?
2. What is capitol of US
3. Which country we fought during Revolutionary war.
4. Which ship brought pilgrims to America.
5. How may stripes are there in our flag.
6. Which president freed the slaves.
Then, I was asked to write down the short sentense "it is a good job to start with".
After that, she gave me a letter with "Congratulation" and asked me to be in the waiting room for Oath Ceremony at 5:00pm. Interview last just 5 min. or so.
At around 4:30pm, I was called to sign on naturlization certificate and surrender green card. The oath ceremony started at 5:30pm. The video from the President part was skipped as it was not work well , so ceremony lasted just only about 20 min. Then, all of us were freed.
Regardin, driving and parking, I got lost some what as I took exit 58 from Route 78 express. However, I asked at a gas station and they knew where the immigration building was. I parked in paid parking at the intersection of Walnut and Orchar Street.
