You can’t get a work permit on a DTV and can’t legally work in Thailand with a DTV. You’ll need to apply for a Non-B visa and a work permit before working.

@Gregory ******

That's correct. When extending in-country with immigration.

@Marcin ***********

It depends on the reason they denied you. They will put a note in the system, and you may or may not be able to enter again either immediately or after some time.

@Marcin ***********

They will not revoke it, but they may deny entry or simply question you (ranging from a quick check to a more detailed interview). Revocation can happen, but usually only in cases of misconduct or criminal activity.

@Marcin ***********

Yes, that's correct. The MFA issues the DTV, while Immigration is responsible for border and in-country controls and certain visa renewals. That’s why you may still be checked, even if you already have a visa. Obtaining a visa is an initial screening step to help authorities prevent crime, but it is not a long-term guarantee especially for visas valid for up to five years.

@Marcin ***********

Your visa is permission to stay for a specific duration and purpose. It does not grant you immigration immunity.

@David *******

Yes, as Bob mentioned, you can't get a 90-day extension. Either you leave on or before the 180th day or you apply for a full extension (180 days) with immigration which requires the same full documentation as when you first applied. If you manage to extend with immigration, you'll then need to do your 90 days.

You aren’t supposed to report anything, since you’re expected to leave on or before the 180th day. Or are you planning to extend with immigration for a couple of days only?

Good luck! 😂

@Christopher *******

It's not only about it. There are plenty of sensitive topics.
