DTV Extension in Thailand: One 180-Day Extension, Step by Step

The short answer

A DTV gives you 180 days per entry, and each entry can be extended once, inside Thailand, by up to 180 days, which is still the rule on the Royal Thai Embassy in London's page updated 8 September 2026. You apply at the immigration office for the area where you live, on form TM.7 (plan to go in person), and the published fee is ฿1,900. Bangkok's office publishes a DTV-specific list: at least ฿500,000 in a Thai or verifiable foreign account "not less than 30 days prior to the application date" (or a guarantee letter), proof of your work or activity, proof of address, and copies of your TM.47 and TM.30 receipts. Leave Thailand without a re-entry permit and the extension ends; your next entry on a valid DTV starts a fresh 180 days.

Updated 17 October 2026. Nothing we read that day changes the extension itself. What changed around it this year: since 31 August 2026 missions such as Vientiane and Savannakhet take DTV applications only from their own country's nationals or permanent residents, and since 15 September 2026 land-border entries on the 30-day visa exemption are generally capped at two per calendar year. Siam DTV is an independent private consultancy, not affiliated with the Thai government or any Thai mission, and everything below can be done without us.

How 180 + 180 works

The Ministry of Foreign Affairs announced the DTV on 29 May 2024 with a stay of "180 days (1 time extension of stay at the Immigration Bureau for a period not exceeding 180 days)". The Royal Thai Embassy in London, page updated 8 September 2026:

"Extension of Stay (through the Thai Immigration Bureau): One time for a period not exceeding 180 days per entry."

"After the maximum stay of 180 days + 180 days, the visa holders need to depart Thailand and re-enter the country with the same DTV visa within the visa's validity date."

Helsinki (updated 3 September 2026) and the Dubai consulate's 2024 DTV checklist say the same in substance. Three things follow.

• The unit is the entry, not the year. Each new entry gives a new 180 days and one more extension.
• "Not exceeding" 180 days. No page we read says whether the new period runs from your current permitted date or from the day of approval. Read the date in the new stamp before you leave the counter.
• The five-year validity is the outer wall. After that you need a new visa, and a new DTV is filed at thaievisa.go.th from outside Thailand: Washington DC, for one, says it "is unable to issue visas for foreign nationals who are currently in Thailand". Since 31 August 2026 the Vientiane embassy (page updated 28 August 2026) requires applicants to "Be a national or permanent resident of the country where the visa application is submitted", as does Savannakhet, so a run to Laos for a new DTV is over for anyone living here who is not a Lao national or permanent resident; see getting a DTV from inside Thailand.

Where and when to file

London tells holders to "contact the Immigration Bureau directly once you are in Thailand", which in practice means the office for the area where you live. Bangkok's Immigration Division 1 is "Responsible for Immigration Services in Bangkok area only", and its FAQ places Chonburi under Division 3, Chiang Mai under Division 5, and Phuket and Surat Thani under Division 6. The same FAQ sends anyone extending on a new passport to "the Immigration Office in the province where you reside".

Where you live	Office	DTV extension list published?
Bangkok	Immigration Division 1, Government Complex, Chaeng Wattana Road	Yes: item 39 on its extension page
Chiang Mai	Chiang Mai provincial immigration (Division 5)	None found. Its public-service manual lists extension categories, the Special Tourist Visa among them, but no DTV
Phuket, Koh Samui	Provincial offices under Division 6	None found
Pattaya	Chonburi provincial immigration (Division 3)	None found

"None found" means we could not find one on those sites on 17 October 2026, not that the office asks for less. Outside Bangkok, prepare to Bangkok's list and ask your own office what it adds or drops.

Go yourself. Bangkok's DTV section is silent on attendance, but the Immigration Bureau's extension-of-stay page (timestamp 9 January 2026) requires it for tourism and business extensions: "คนต่างด้าวต้องมายื่นคำร้องด้วยตนเอง" (the foreigner must file in person). Bangkok's Thai text classes the DTV as a tourist visa of a special type, so plan on the same rule. The extension is a stamp in your passport; take it there yourself.

When. We found no official page that says how early a DTV extension may be filed, so ask your office what it accepts. Do not let the permitted date pass while you wait: from the next day you are overstaying, at ฿500 a day (Bangkok FAQ).

Online. Bangkok's site lists 12 reasons its e-Extension service (thaiextension.vfsevisa.com) handles, and the DTV is not named among them. "Tourism" is, and the page does not say whether a DTV counts; it also says that in the first phase the visa sticker is collected from Division 1 at Chaeng Wattana. The Bureau's THIM app lists "Visa Extension" as a planned service (25 September 2026). Assume a counter visit.

New passport? Bangkok's FAQ says the entry stamp must first be transferred to it, at the visa extension section of that provincial office.

One applicant's account. A forum post dated 24 June 2026 reports a preliminary stamp at Bangkok's DTV counter and "a second trip to the I.O. to officially get my stamp in two weeks", with ฿1,900 paid. One report, not a procedure, but reason enough to keep the following fortnight free of travel.

The fee: ฿1,900, and where ฿10,000 comes from

Bangkok's fee page lists "Extension for Visa 1,900 baht" and says "Fee is not refunded under any circumstances." The Bureau's extension-of-stay page gives "ค่าธรรมเนียม 1,900 บาท" (fee 1,900 baht) for tourism and business extensions. Neither names the DTV, which Bangkok's Thai text classes as a tourist visa of a special type ("ประเภทนักท่องเที่ยว ประเภทพิเศษ"), and Bangkok's DTV section states no fee. No official page we read sets a different fee for a DTV extension, so ฿1,900 is the published figure.

The one official document we found that puts ฿10,000 beside the DTV is the MFA's May 2024 sheet, where it reads "Visa Fee: 10,000 baht": the fee for issuing the visa, which missions charge in their own currency (£300 in London, €350 in Helsinki). At least one site quotes ฿10,000 for the extension: a Phuket guide last updated in May 2026 says "Official fee: 10,000 THB cash, payable on the day at Phuket Immigration" and cites no source. If an office asks for a different amount, ask what it covers and keep the receipt.

What Bangkok asks for: the one published DTV list

Item 39 on Immigration Division 1's extension page, "Visa Extension - Destination Thailand Visa : DTV", is the only DTV-specific extension list we found. The page shows no date; the site's own page data records its last edit on 27 February 2025. It covers telework, "other activities" (Muay Thai and martial arts, cooking, sport, medical care, training, seminars, art and music) and dependants. For the first two the test is "Financial evidence or proof of financial support for travel or guarantor of at least 500,000 baht", plus proof of work or activity.

Item	What Bangkok's list asks for	Who
Form TM.7	From the office's forms page	Everyone
Passport copies, photo	"Data page, visa and arrival stamp"; one 4×6 cm or 2-inch photo. If your DTV has no sticker, print the e-Visa too (our suggestion)	Everyone
฿500,000	Thai and/or verifiable foreign account, "not less than 30 days prior to the application date"; or financial support, such as a certificate from your company or employer or a guarantee letter, of ฿500,000 "on the application date", with documents showing your relationship to the guarantor	Main applicants
Proof of work	"a contract for work abroad that is still in effect on the application date or employment history or previous work"	Telework
Proof of activity	For government-supported Muay Thai, martial arts, cooking and sport, a certificate and extension request from the relevant government authority; a hospital certificate; a government invitation; a TCEB certificate; "Activity participation photographs"	Other activities
Proof of address	Rent and payment evidence for a hotel, condominium or house, or an owner-certified copy of the title deed	Everyone
TM.47 and TM.30	Copies of your previous 90-day notification and your notification of residence	Everyone
Relationship	Birth, marriage or adoption certificates	Dependants

The forms page also carries a 2025 consent form, STM.11, that lets Immigration verify the facts of visa, change-of-type and extension applications. The DTV list does not name it; ask whether your office wants it.

The money test reads as 30 days, not three months. The English is muddled; the Thai is clearer: a verifiable foreign account, a Thai account, or both combined, so the published list does not require a Thai account. Our reading: keep ฿500,000 in place, untouched, for at least the 30 days before you file, with statements to show it. That is lighter than the three months of statements that missions such as Savannakhet ask for with the visa application (proof of funds), but if you have spent the money you showed for the visa, this is the line that will catch you.

Soft power: read item 4.1 twice. For government-supported Muay Thai, martial arts, cooking and sport, which the Thai text names, Bangkok asks for "Certificates and requests for extension of stay from the relevant government authorities". Read literally, that is a letter from a public body, not your gym, and the page does not say which body or whether a gym letter will do. Ask the office before you count on one; our Muay Thai guide covers what gyms usually provide.

Dependants show no funds. Spouses and "legitimate children under the age of 20 years" provide relationship documents, address evidence and the two receipts.

TM30 and the 90-day report: the two receipts

TM30 is your host's filing, and your problem. Section 38 of the Immigration Act, quoted on the Bureau's TM30 page, requires the house master, owner or occupier, or the hotel manager, to notify Immigration "ภายในยี่สิบสี่ชั่วโมง" (within 24 hours) of a foreigner coming to stay. The page allows three channels: in person or through someone authorised, by registered mail, or online (the Bureau's system is at tm30.immigration.go.th). Get the receipt for your current address well before your appointment.

The 90-day report runs alongside. Anyone on a temporary stay of more than 90 days must notify their address every 90 days (Bangkok 90-day page): in person "within 15 days before or within 7 days after" the due date, or online at tm47.immigration.go.th "within 15 days but not less than 7 days before the due date" (TM.47 manual). A late report costs ฿2,000. Neither lists a fee for an on-time report.

Where the two meet:

1. Bangkok wants your previous TM.47. Keep every receipt.
2. The extension appears to count as a report. The Los Angeles consulate says "The first application for extention [sic] of stay by the foreigner is equivalent to the notification of staying in the Kingdom over 90 days", but its page was last updated on 30 November 2022 and still sends postal reports to a Suan Plu address; Bangkok's own page now gives Chaeng Wattana. Ask for your next due date when you collect the stamp.
3. The next report is made in person. The TM.47 manual lists "first time of visa extension" among the cases where "the foreigner has to notify 90 days notification in person"; online works again after that.
4. Leaving resets the count, which "will restart from upon the arrival date of his/her re-entry into Thailand. (every case)", says the 90-day page.

Extend, or leave and come back

Bangkok's re-entry permit page: "An alien who is permitted to stay in the Kingdom temporarily, if traveling out of the Kingdom without making Re-entry, it will be considered that the permission to stay in the Kingdom is terminated." That includes a paid-for extension.

On a valid DTV that rarely costs you anything: the next entry brings a new 180 days and a new right to one extension. A re-entry permit (TM.8: ฿1,000 single, ฿3,800 multiple) instead lets you stay on for "the period still remaining" ("เท่าระยะเวลาที่ยังเหลืออยู่" in the page's Thai text), which matters only in narrow cases, such as a DTV that expires before your extended date. That is our reading of the general rule, not anything published for the DTV; confirm it before you fly.

So day 180 is a practical choice: ฿1,900 and an office visit or two for up to 180 more days, or a ticket out and a new 180 days on return. TAT describes the two-per-calendar-year land-border limit in force from 15 September 2026 as applying to travellers using the 30-day visa exemption; it says nothing about visa holders, and nothing we read promises entry to anyone. On an exemption stamp rather than a DTV? See the 30-day exemption guide.

If the extension is refused

We found no published appeal route for a refused DTV extension, and the fee is not refunded.

• Leave by the date your passport now shows. Ask the officer which date applies before you leave the counter.
• Do not overstay. The fine is ฿500 a day up to ฿20,000 (Bangkok FAQ). Under Ministry of Interior Order No. 1/2558, if you hand yourself in, an overstay of more than 90 days brings a one-year re-entry ban, more than a year three years, more than three years five, and more than five years ten; if you are arrested and prosecuted, five years for up to a year and ten beyond. Bangkok's STM.9 form prints the same table and dates the order 27 November 2015.
• The visa itself. Nothing we read says a refused extension cancels the DTV, and nothing we read says how a refusal is treated when you next arrive.

If you have already overstayed by more than a few days, have been detained or arrested, face a court case or think you may be on a watchlist, speak to a licensed Thai lawyer, and contact your embassy if you are detained.

Doing it yourself, step by step

1. Check the permitted date in your passport (on a new passport, have the stamp transferred first), and ask your office how early it takes a DTV file.
2. Get the TM30 receipt for your current address, and find your latest TM.47.
3. Make sure ฿500,000 has been in place for at least 30 days before you file (our reading of Bangkok's test), or arrange a guarantee letter.
4. Gather proof of your work or activity, and proof of your address.
5. Fill in a TM.7, sign your photocopies (the Bureau's own extension page asks for every sheet to be signed in its business category), and take the originals and ฿1,900 to the office yourself.
6. Read the date in the new stamp, and make your next 90-day report in person.

None of this needs an intermediary, and nobody, whether agency, lawyer or us, can promise you an extension; anyone selling "contacts", a fast track or a guaranteed stamp is selling something that does not exist. What agencies charge for extension help is in our cost guide. Siam DTV is a private consultancy, not affiliated with the Immigration Bureau, the Royal Thai Government or any Thai mission.
