I need to get a new passport soon, becsause there is not much space left. I am currently in TH with a SETV. What do I have to do to get my visa transferred to my new passort?
TLDR : Answer Summary
When obtaining a new passport while in Thailand with a Single Entry Tourist Visa (SETV), the visa itself cannot be transferred to the new passport, as it is tied to your old passport. Instead, you will need to carry both your old and new passports when leaving Thailand. It is advisable to consult your consulate for proper documentation, which may include a letter for immigration purposes when coordinating your travel.
