I have received my conditional approval, and naively thought that scheduling an interview would be easy. I have an up-coming trip through LAX in about a month, and scheduled y arriving flight to allow all morning to schedule my interview. To my surprise, I found that the entire day is booked, and that many days in February are unavailable. I looked at Long Beach, and the entire month of Feb. is booked.
Surprisingly, the situation at JFK, for example, is the opposite, with most days available, so scheduling an interview may be very easy at some centers and difficult at others. I'd like to a avoid the need to tie up a whole day flying to LAX and home ( not to mention the expense) simply for an interview that seems to be a formality! As others have suggested, I'll keep trying to schedule at LAX, but if I can't maybe I'll take my chances as a walk-in.
