I have just received a new British passport in Hua Hin and old passport now cancelled. How do I go about transferring visa from old to new passport, is there any paperwork to complete before I visit Imigration?
TLDR : Answer Summary
To transfer your visa from an old British passport to a new one in Thailand, you'll need to check whether you have a visa or an extension of stay. If it's an extension of stay, you must bring both passports and a letter from the consulate to the local immigration office where your extension was issued. In some cases, different immigration offices may have varying requirements or fees for processing the transfer. It's important to confirm the process as it may differ between Hua Hin and other locations in Thailand.
