Here is a link to a few regional passport acceptance fairs. If you need a passport and live near one of these locations, this might be helpful.

Unfortunately that is not going to help with the current backlog. The wait time for processing is now 10-13 weeks, according to the agency.
I applied to renew mine by mail in April, and paid the extra $60 for expedited processing. I recipeived my new one 6 weeks later, which was a great relief!
Do the passport people not realize that there are a lot of states between CA and NJ?
I sent my renewal in June 20 and it is in the system. There is a fun website called passportwaitingtime.com (not connected with the State Dept) that has the current wait for a normal adult renewal at 59 calendar days. Expedited is only 8 days faster based on their data.
