I started my renewal back in early April, just before the summer rush. Their website acknowledged receipt of my application on April 11 (even though USPS tracking showed they actually received it April 4). I received new passport June 9. So almost 9 weeks. Did not pay for any expedited services.

BUT, about 4-5 weeks after they received my application, I received a letter claiming my application couldn't be processed because "electronic signatures" were not acceptable...i was really surprised they noticed a scan of my actual signature was added to the application using Acrobat Pro...to the naked eye, the signature on the printed app looked legit, and i've signed many other documents using this procedure without issues....anyway, i had to print out the app again (app had been filled out using Acrobat) but actually sign with pen, and submit in special envelope to a special address....so this most likely added 1-2 weeks to my experience

so beware using electronic signatures
