New citizen
I went back to look at my passport, 7/20/98, exactly 11 years ago, was the first time I got my Visa to US. And I still remember pretty well how long that day was, and how exhausted I was after 10 hours waiting. 11 years is not short in a life journey -- so many things happened since I came to the US.
Here are my experience today:
My wife and I had the same appointment time at 8:40am. At 8:20 we were at the security check point. To my surprise, there was't too many people in the line. I was under impression that the line could be as long as in the airport. I dropped off my interview letter at the second floor information desk and was told to wait for my name to be called. There were 60+ people already in the room. and you can tell there came from everywhere in the world.
The agent came out calling for interviewee every 1~2 minutes in average, so the line moved quickly. I guess they had a lot of interviewer. My wife was called in at 8:35, mine was a bit late, around 8:45. My interviewer was a nice lady. The process was as simple and straightforward as I could ever imagine, she checked my (PP, GC, DL), reviewed the N-400 form, 6 civil questions, read/write test -- and that's it... didn't ask any questions that required me to even think a second... She didn't actually say anything about passing the interview, but "do you have time for the ceremony today?", (sure that will be great!), "I think they still have open slots at 11", (that's even better!). So at 9:00 am I was out from the interview room, and I saw my wife already waited me in the lobby. She had the same result as I did.
We were told to come back at 10am to check in for ceremony. The ceremony detail is pretty much the same as someone mentioned in the "experience" thread, I had the same location, so no need to repeat here. At 11:30am we were out as US citizen - finally, 11 years since we first came.
We went nearby post office to apply for passport. For the people who have the same office (Washington DC/Fairfax), you can use the Merrifield Post office, only half mile away from the USCIS office. They have copy machine so you can make a copy of your certificate as the original one needs to be mailed along with your passport application.
That's all - comparing with my green card, H1B, F1, this is the best experience I had with the INS/USCIS. As the director said in today's ceremony, one of the best things of being citizen is we don't have to come back to see them again!
Good luck to everyone!
