Full DTV guide: DTV Thailand 2026 · Embassy seasoning · Jomtien Immigration · Extension timeline

What the official DTV rule says

The Ministry of Foreign Affairs' DTV material and the Royal Thai Consulate-General in Ho Chi Minh City, checked on 1 August 2026, publish a 5-year multiple-entry visa with a stay of up to 180 days per entry. They say the holder may apply to Immigration for one extension of no more than 180 days. “May apply” is not a guarantee that the full period will be granted.

After the original stay and its permitted extension, the MFA material says the holder must leave Thailand and may re-enter with the same DTV while the visa remains valid. The official rule checked on 1 August 2026 does not establish repeated extensions of one entry.

Fee and form: what could be verified

Immigration Bureau public handbooks checked on 1 August 2026 publish the standard temporary-stay extension application as TM.7 and the application fee as 1,900 THB. The handbooks predate DTV and are not a DTV-specific Jomtien checklist, so confirm the live category requirements with the responsible Immigration office before filing.

Document checklist: national rule versus local request

No current official DTV-specific extension checklist for Jomtien was found in the Immigration Bureau material checked on 1 August 2026. Treat the following as preparation questions, not a settled local checklist, until Chonburi Immigration publishes or provides its current list:

The current official Jomtien material checked does not publish an exact photo count, copy set, bank-letter format, TM30 printout, lease or map requirement. Ask the office which items apply to the intended filing.

Financial proof at extension

The MFA's national DTV summary, checked 1 August 2026, publishes financial evidence of at least 500,000 THB for the visa application. The current Savannakhet consulate page also publishes that amount and its own evidence period for applications made there. Neither source establishes a universal Jomtien extension “seasoning” rule or requires every DTV extension applicant to produce a stamped bank letter.

Reports that Jomtien sometimes rechecks funds are practice reports, not a published national rule. Ask the office what balance evidence and bank format it currently requires for the intended filing date.

DTV extension and 90-day reporting are separate

The Immigration Bureau's Thai TM.47 material, checked on 1 August 2026, says a foreign national permitted to stay temporarily must notify Immigration for each 90-day period in Thailand. It also states that this notification is not an extension of stay. A DTV stay can therefore have a separate reporting clock; use the due date issued for the individual record rather than calculating from this article.

Travel, work and tax

The current MFA material calls DTV a multiple-entry visa. Travel can end an existing permission to stay even when a valid multiple-entry visa can support a new entry, so confirm the effect on any granted extension with Immigration before departure.

Work permission and tax are separate from an extension decision. See the current work-boundary guide and separately sourced DTV tax guide.

Jomtien timing and refusal claims

Current Chonburi Immigration material does not publish a universal arrival window, queue forecast, advance-filing interval or fixed refusal list. Do not rely on local anecdotes to choose a last filing day; contact Chonburi Immigration before the permission-to-stay date in the passport.
