@Bill ********
Same as you.
I want to renew my passport that will expire in June next year.
No changes.
I have a confirmed appointment with vfs.
When I noticed the birth certificate is required.
I replied to their email confirmation. Asking were they sure about the birth certificate. And not just the old passport.
All they would say is. I have a confirmed appointment that can be rescheduled. But if I don’t show. I have to pay 1500 thb or thereabouts.
Thanks for your reply
