March 24 update
I applied in early July 07, I've posted my timeline below to help others, as I was helped.
I had an InfoPass appointment for 3/21 and actually received my Interview Letter the day before the appointment. I decided to go anyway since I had plenty of general questions, and talking to an Immigration Officer is a rare treat. This was at 300 N. Los Angeles St. downtown.
On this message board, some of the terrified questions posted, and the lengthy lists of items to bring to the Interview are really daunting/overwhelming. But it seems from the feedback posted here, and from what I gathered during my InfoPass appointment, that the immigration officers in LA are actually quite nice, and the Interview process is quick and painless. The only challenge seems to be to answer the 10 civics questions, and that isn't too much of a challenge.
So if you're an average Joe or Jane, you won't even need the 10,000 pages of supporting documents that you're hauling with you to the interview. You'll be in and out in 15 minutes.
One thing I learned was that if you have an early morning Interview, you're more likely to receive an Oath Letter that day. They run out of them as the day goes on, and you're more likely to be mailed yours.
My friend, who applied in late July, also had an appointment. She was told that her name is still in name check in Laguna Niguel.
