Do I need to maintain the 500,000 Baht deposit for the DTV visa during extension or re-entry?

Think about the reason why there has to be a 500.000 Baht deposit !

If you get involved in a accident, get ill, get fines, financial disputes, pay for Airplane ticket out of Thailand etc. then you should be able to pay for yourself immidiately with money from the deposit, because Thailand is feed up with people not able to / want to pay their own expenses, when they stay in Thailand.

That was the reason for the deposit, as discussed before the DTV came into effect.

That’s also why the deposit should be immidiatly accessable and not in crypto, stocks or what ever.

So it would be the best not to touch the majority of the deposit, you may suddenly need them , and the Thai authorities will expect you to have them avaiable.

When you look around in this group there are a few reports of people getting into the country on DTV asked to show they have 500K.

For an extension in country you always need to show you comply with all requirements.

If you not comply with requirements anymore you will not get an extension.

Best is to do an organized border bounce then, not on your own, to prevent the risk of being checked on re-entry.

Extension yes

Re entry not as of now

Not required for re entry.

For extension, it is required.

For reentry, it is, so far, not required or let's say almost not checked at all (only a few rare cases).
