Passport Renewal by Appointment

Hi, I am applying for passport renewal by appointment at Washington DC center.

I see a lot of people have sent it via mail but has anyone gone through the process of applying by appointment?

Can someone share their experience and any points we need to take care.

Hi, the appointment went smooth but they took my headshot again since the pictures submitted were old as they got to know by looking at your visa page.
