As a follow up, I was approaching 12 weeks and asked my Rep’s office for help. They got back to me in a couple of days and warned me that even congressional inquiries were taking as much as two weeks for an answer. But a day later they forwarded an email from the State Department saying they would check but maybe there was an outstanding issue I hadn’t responded to.
Online status still shows “in process” but my passport was mailed the next day and in my box two days later.
So, not scientific, but I think some applications are getting “stuck” somewhere in the system.
I am still waiting for my passport card though. I know those used to be mailed separately, so I’ll give it a few more days.
