Hi Sapro,
Sorry.. I was on vacation. Yes I completed my interview on dec 17th. My interview was at 1 PM. So I could not take oath on same day as it was late for 2:00 PM ceremony. So I took the oath next day.
Overall my interview experience was OK. The IO was a lady and she was looking bit tired and sounded bit curt to me since beginging. But she was not rude. It may be because it was after lunch time. IO was talking with some accent which I would guess was European (European spanish or portugeese ... This is my guess..)
She asked for my passport, GC and driving license. Then She went thru' my application and asked me some questions on information I filled in application form. I mentioned to her about my traffic tickets and told her that I should have checked the box 16 instead of box 15. She made those changes. She glanced thru' rest of my application. Then she handed me the paper with all information filled to verify name and rest of the information. There was a spelling mistake in my middle name. (unfortunately I myself did that mistake in application form & did not realize till that moment). I showed her my passport and she went thru' my file to check for the spelling. Then she corrected the spelling and printed new form. Then she took the copy of first page of my passport. The file she had contained all the documentation I submitted for my GC processing and N-400 processing. The file was pretty thick.
Later she gave me the oral test. The test was printed on paper and there were boxes for Correct and incorrect. She was asking the questions and based on my answers she marked the boxes. I think I answered all of the questions correctly. But she was asking questions very fast. So I had to really concentrate.
They she printed another paper which had an english statement written which she asked me to read and later told me one statement to write. After that she said she was going to approve my application and stamped a red stamp on my application.
Later she suddenly asked me if I have any documentation on my traffic tickets. I told her no because they were very old and I could not get them. I took a copy of my driving license history which was clean. I showed her that. She made comment that it says nothing about tickets. I had a copy of parking ticket which I showed her. She glanced at it, smiled (May be smirked..) and commented, 'but this is paid'. I just nodded. Then she asked me if she can keep the copy and I said sure. Then she asked me if I have cell phone in case they need to contact me. I gave her my cell phone which she noted on the application. Then she gave me the appointment form for the oath next day and said you can go now. I said thank you and left.
Overall experience was OK. Based on experiences posted on the board, I was had bit different idea about the IO.
Reason I am mentioning this is that, best thing is to do is to keep cool regardless of what happens.
Oath experience was pretty normal. Nothing specific to mention. All you need is GC and oath appointment letter.
