Going by history: no, at least not generally.

Routine renewal service for non-expired passport
 

9/16 Sent via USPS Priority Mail
9/23 Received for processing
9/24 Approved and Shipped
9/27 Delivered

That was unexpectedly fast.

Received an email today stating my passport renewal had been approved and would be printing. Two hours later I received another email, stating that they had received it on September 13th and that they were now reviewing my application?! My husband also received the approval email and has already received a shipping notice. Does this mean there was a problem with the photo, or am I panicking too soon?

First time and renewal at Frankfurt consulate
 

Not sure if this belongs here, but I applied for my son's CRBA and passport at the Frankfurt consulate in September and 8 days later received both (from the consulate), which means they received them from the US at least a couple of days prior. I'd also renewed my passport card in person and received that too. Super fast.

4-14 calendar days is normal for CRBA + first US passport to be back for a young US citizen child when it comes to ACS in the EU. It's been this way for years, and no expedite fee is applicable for such turns. The variance in processing times has been lower than it is for domestic US applications, and there are multiple reasons for that.

The most common major delays experienced for CRBA+first US passport tend to be if the parental applicants decide to not do a pick-up in person and the domestic/regional mail courier service messes up/slows things down or if the parental applicants are waiting to be contacted to know when to come to pick-up the CRBA+passport in person. If someone who does a CRBA+first passport for a child in the EU and doesn't get it back within 14 business days, I would take it as a sign that something went wrong somewhere.

First time passport - Regular Service

I renewed my passport by mail and requested routine processing:

* Sent the application (DS-82) via USPS on Aug 22
* The passport center received it on Aug 26
* New passport shipped on Sep 18
* Arrived on Sep 21

The new passport had a picture defect, so I submitted DS-5504 (also routine processing):

* Sent the application (DS-5504) via USPS on Sep 24
* The passport center received it on Sep 30
* New passport shipped on Oct 4
* Arrived on Oct 7

It seems that they process DS-5504 much faster than DS-82 (5 days vs 22 days). Still, even regular service DS-82 is significantly faster than 6-8 weeks that they mention on their website.

My mother in law applied for a first passport on 9/26 and received it this past Tuesday (10/15). We thought there might be an issue since she was born in Germany (at a U.S. Army hospital to U.S. parents) but we were able to find the documents she needed. I was impressed it was that quick.

Super helpful thread. Adding my data for an expedited application, first-time adult passport after naturalization. A highly impressive 10 days from mailing the application to getting the approval, which includes 4 weekend days in the middle!
