Interview went well yesterday. Appointment was at 830, got there just after 8 (actually arrived a little before 8 but waited in my car since it said not to get there more than 30 minutes prior). I was called in a little after 9. Interview took about 20 minutes.
Officer introduced himself, explained what we would be looking through. He asked for my driver's license and permanent resident card. He asked for our 2007 tax return and copies of our kids birth certs (which was part of my application). He went through the application - name spelling, birth date, address, phone number, some of the yes/no questions at the end of the form. He then had me sign the form in 2 places. Then he had me sign the pictures and he stapled that to the application. Next, he handed me a sheet of paper to write a sentence down. Next, he had me read a sentence from another sheet of paper. He then explained that he had 10 random questions from the possible 100, and that I had to answer 6 of them correctly. I got the first 6 right, so he didn't ask the rest (got some really easy questions: 3 branches, who becomes pres if pres dies, who advises president, number of senators, term of house of reps, color of stars).
He gave me a piece of paper that said I was approved, and a handout about oaths. I asked whether it would probably really take 90 days to get an oath since our house was on the market and I would really like to take the oath before we move. He said that it probably would take that long. Now I can worry about what happens if we move before I get scheduled for an oath, sigh.
