Thank you for this great guide.
Was very helpful in my passport renewal process.
I had mine renewed at CKGS-Chicago.
I chose to walk-in to drop-off and pickup.
Very helpful staff and my passport was ready for pickup in 3 weeks like they said when I submitted the application.
I only notarized the ‘Change of Appearance / Signature Form’ as that’s what they wanted on the final checklist and self-attested the other documents…
