EXPERIENCE ARRIVING IN PHUKET TODAY:
Left Phuket on a business visa (planning to return and cancel it before activating DTV)
Went through the ‘fast track’ at immigration and they said I had to enter on DTV (I didn’t tell them I had DTV, it obviously just came up on their system).
I told them I was advised I had to come back and cancel my business visa and work permit but they asked a few staff and said that wasn’t correct so stamped me in on DTV.
They were very pleasant about it so just an FYI!
