Anyone who holds UK passport have experience to certify the passport at the UK embassy in Bangkok. If yes, may I know require how long and how much? Does it requires to make appointment beforehand?
Thank you.
TLDR : Answer Summary
To certify a UK passport at the British Embassy in Bangkok, you need to make an appointment online. The certification is completed during the appointment, which may take a few weeks to schedule, though last-minute cancellations could allow for earlier appointments. Payment can be made by card, but not all cards are accepted, and cash must be the exact amount since no change is provided.
