but as it's not required, even if the airline does check, it just means they made a mistake and you can just tell them that. Then they'll have to let you board. Asking them serves no purpose either.
but since it's not required, the discussion evolves differently than in case they would be correct. You can tell them it's not required and ask them to double check with their supervisor if necessary.
They are doing what they're supposed to. And what you are supposed to do: go home. What do you think gives you the privilege to stay long term in Thailand on exemptions and extensions?
All immigrations offices should refuse the extension in this circumstance.
yeah strange. I do vaguely recall that some border was indeed not aware, but it's a bit much to advise against using them to activate a DTV indefinitely. Everyone should by now be aware that it exists.
Besides, you cannot not use a visa if you have one. If you have a DTV, they can't even stamp you in otherwise.
