Each embassy is free to make their own requirements.

that's still importing...

If your application is asking for those things then you chose the wrong visa. A 90 day non-O visa does not require medical certificate or criminal records check.

@Steve **********

no because then you're guaranteed to have to pay duty for importing goods

Don't worry, they would've come up with another reason if it wasn't the make-believe appointment. Many immigration offices don't want to do DTV extensions, so they'll give you crazy requirements. Then if you meet those requirements, they'll say "But you need this too" and keep doing that until you stop bothering them.

@Marco ******

someone just posted recently about leaving and coming back and getting fined by immigration. The correct way is to cancel it along with your work permit. Regardless of what you were told.

@Marco ******

visa exemption and tourist extension are no indication at all. You can do those perfectly fine if you didn't cancel your work extension because those are not long term visas or extensions. But if you tried to apply for a new non-B or another long term visa, you would have problems.

@Jeremy *****

you wouldn't have any issues entering as a tourist even if they didn't do what they said. No one will care until you do to immigration to try and get a long term visa or long term extension.

@Marco ******

that's WRONG. YOU have to cancel your own work permit and your own extension. It doesn't matter if you leave. It doesn't matter if your extension expires. You are still REQUIRED to notify immigration and cancel per the document you signed.

I doubt you're on a non-B visa. You are probably on a work extension, not any visa at all. If the stamp in your passport says "extension of stay" then you signed a document that said YOU would notify immigration if your circumstances change. If you stop working, that is a change of circumstances, and you are REQUIRED to notify immigration, regardless of when your extension ends. If you do not take your cancelled work permit and documentation about your work ending to immigration to cancel your extension, then you will be unable to get another long-term visa or extension in the future until you do cancel it, and you will be fined 500 baht per day, up to a maximum of 20,000 baht, for failing to notify immigration you stopped working.
