My interview was scheduled at 3pm. I showed up around 2:15 and went right in. Handed my interview letter at window # 7. There were about 15-20 people in the lobby. A few people came in after me and were called in before me. I pretty much sat there and saw people go in and out. Now its 4pm and my name is still not called. By then I was the only person left in the lobby. I started wondering if they lost my appointment letter of or if there were any issues. By 4:15 someone came out and asked me if I was waiting for an interview, upon which I replied Yes he asked for my GC to find out what's going on. With in a few minutes another officer came out and finally called my name. Apparently I was his last appointment and the guy he was escorting out was an orderly gentlemen probably 80 plus. As I was being walked in he introduced himself and apologized for the long wait, as his last appointment ran over an hour.
Finally I made it to his office and he took me under oath and asked me to sit down. He was still in the process of clearing his desk. Finally he brought over my file and started flipping through pages and told me he was looking for something. While he was doing that he asked me to present my passport, green card and license. Then he started to go over my application question by question and verified everything. He asked me if I wanted to change me name and I said No. I had recently switched employers so I updated that information on the application. He briefly looked at the update and did not bother to ask any other questions about the new employer. He also flipped through my passport.
Afterwards he asked me to read and write the following sentence:
Question I read “What was the first capital of United States?”
Answer I wrote “New York was the first capital of United States”
He then read what I wrote and replied that I have passed reading and writing part.
Then he told me that he will take the civics test. I don't recall all the questions but I went through them very quickly. I answered all 6 right and he stopped there and replied that I have passed civics exam. After that he finally gave my 2 papers and congratulated me and shook my hand. My oath letter should arrive with in 2 months.
The whole interview process lasted 20 minutes the most. Even though I had taken tons of paperwork with me I was never asked to show anything other than what I described above.
