I actually was pleasantly surprised how smoothly everything went. Went in waited for about 10minutes and did the civic portion first with one person then asked to take a seat for the actual Interview. The Officer was very professional and pleasant. Went over my application, asked a few questions, made a few corrections on my application (I had put more dates of travel outside of USA on my application than was necessary.)...I put almost 5 years worth instead of the 3 years I was applying for. Oath ceremony is on 03rd!! I had sent in my Application for citizenship in mid October...Overall a very quick process.
