Do I need to visit an immigration center in Bangkok with the same documents for DTV renewal after 180 days?

Yes, generally, to renew the DTV after 180 days, you will need to go to an immigration center in Bangkok and may need to present the same documents you used for the first application. However, it's important to check if there have been any changes in the requirements.

I recommend contacting Expat Money Forum , as they can help you with detailed information and support throughout the visa renewal process.

As mentioned by Brandon, the extension process isn't yet known.

The way around this is to leave the country briefly and then re-enter and get another 180 day stamp. No paperwork, fees, etc. Just the cost of the travel. Can do this as many times as you want during the 5 year visa validity.

I thought after 180 days you have to leave Thailand and come back?

If it’s the same documents they will need to be updated, such as bank statements.

There is no such thing as renewing a visa.

For DTV you can apply one time each entry for a 180 day extension and you would do that at your local immigration office.

No one knows what it will require because no one has gotten one yet. And the requirements will be different because each immigration office sets their own requirements. You'll need to go to your immigration office and ask what their requirements are. But many immigration offices don't seem to know yet either.
