Looks like most of us are in the same boat that are still waiting for the passports. We just went through the citizenship application process and now are entering another wait game.
Since my application is overdue for more than 2 business days, I called them twice (Both calls were more than an hour and a half of waiting with 400 calls ahead of me). I just got the info that my application has been approved, but not ready for mailing. And the passport will be mailed out at any time soon.
I guess our applications are being processed on time, unless you get any notification about missing info.
In my opinion, they just don't get enough printers
or can't keep up with the passport material
due to the higher number of new citizens.
