We (myself and spouse, left the kids with a sitter) had our interview on 1/22/2010 and it was smooth. First, you drop off your interview letter in a box and then you wait until they call your name. The first Officer took me to a small cubicle and he asked me the six questions (How many amendments in the Constitution - 27; Who makes federal laws - Congress; What is the name of the VP - Joe Biden; What is the highest court - Supreme Court; What group was taken to America as slaves - Africans; Why did the colonists fight the British - taxation without representation). He was very polite, and we made some small talk about taxation and my occupation.
After answering these correctly, I waited again until I was called in for my formal interview. The interviewing Officer (a different Officer) was very polite. She introduced herself, and placed me under oath. She went through my application, asked about some travels that I had taken, where I had lived, who I worked for, family questions, etc. Since everything was in order, she told me that my application was being recommended for approval and that I would wait in the lobby until given further paperwork (N-445) for the oath ceremony scheduled for February 3rd, 2010. The documentation that you are given is a form N-445, and it basically tells you to bring that N-445, your green card, and any immigration documents that you may have. I'm not sure what exactly they mean by any immigration documents that you have - 10 years of documents is a pretty big file
Nonetheless, we're very excited to be bringing this process to a conclusion and taking the oath on February 3rd, 2010. We'll take the kids to the oath ceremony and enjoy some hot dogs and apple pie!
