I have enough to correct the article. Two claims collapsed under primary sources, and several numbers were internally inconsistent.

The short answer

Three separate things get lumped together under "DTV visa cost", and they behave completely differently:

Cost	Range	Who sets it
Government visa fee	£300 (London), US$400 (Washington DC), S$500 (Singapore), AED 1,500 (Dubai), NZ$2,000 (Wellington)	The individual Thai mission
Third-party costs	฿0 for many applicants; ฿1,000–5,000 for translation; more if your mission requires embassy legalisation	Translators, notaries, foreign ministries, your bank
Consultancy fee	฿0 if you apply yourself, otherwise roughly ฿3,000 to ฿24,000 (US$100–700)	The firm you hire

The government fee is unavoidable, non-refundable and charged per person. The consultancy fee is entirely optional, and for a clean case it buys you nothing you cannot do yourself in an evening.

Everything below is sourced from the missions' own published pages. Where a figure is not published anywhere official, we say so rather than filling the gap with a number.

The government fee is set per mission — and the spread is wider than you have been told

A great deal of DTV content online repeats a line to the effect that "fees are standardised across embassies, so choose on convenience rather than cost." That is wrong, and it is provably wrong from the embassies' own websites.

Here is what missions actually publish for the DTV:

Mission	Published fee	Approximate USD equivalent
Royal Thai Embassy, London	£300 (all three DTV categories)	~US$390–405
Royal Thai Embassy, Washington DC	US$400	US$400
Royal Thai Embassy, Singapore	S$500	~US$370–390
Royal Thai Consulate-General, Dubai	AED 1,500	~US$408 (AED is pegged to the dollar)
Royal Thai Embassy, Wellington	NZ$2,000 per person	~US$1,150–1,250
Royal Thai Consulate-General, Los Angeles	No fee published on its DTV page	—

The USD conversions are our arithmetic at recent rates, not figures published by anyone; treat them as indicative and expect movement.

London, Washington DC, Singapore and Dubai all sit broadly between US$370 and US$410. Wellington, which restricts applications to residents of New Zealand, the Cook Islands, Samoa and Niue, publishes NZ$2,000 — roughly three times the others. That is not a typo and it is not agency chatter: the figure and the words "per person" are on the embassy's own visa types page.

Some missions publish no DTV fee at all. The Los Angeles consulate lists the required documents for the DTV but not the price. Phnom Penh's DTV page likewise lists documents without a fee — the US$400 figure you will see quoted for Cambodia comes from aggregator sites, not from the embassy, and we are not going to launder it into a fact. The same applies to JPY 52,000 for Tokyo: it appears on aggregator pages, we could not find it on the embassy's own site, and so we report it as unconfirmed rather than as a fee.

Practical consequence: check the fee on the page of the mission you will actually apply to, on the day you apply. Do not budget from a blog table, including this one.

Jurisdiction is enforced, and it can be the largest cost of all

You do not get to shop for the cheapest mission. Jurisdiction is documented and applied:

• Singapore states plainly that the DTV "will only be granted by the Royal Thai Embassy Singapore to Singapore citizen and Singapore Resident."
• Wellington accepts applications only from residents of New Zealand, the Cook Islands, Samoa and Niue.
• London requires non-UK citizens to submit a copy of a BRP card or a letter from UKVI confirming settlement status.
• Dubai requires every applicant to hold a valid UAE residence visa with at least three months' validity.
• Los Angeles covers thirteen states plus the US Pacific Territories: Alaska, Arizona, California, Colorado, Hawaii, Idaho, Montana, Nevada, New Mexico, Oregon, Utah, Washington and Wyoming.
• Washington DC covers fifteen jurisdictions: Alabama, Delaware, Florida, Georgia, Louisiana, Maryland, Mississippi, North Carolina, South Carolina, Tennessee, Texas, Virginia and West Virginia, plus the District of Columbia and Puerto Rico.
• New York covers ten: Connecticut, Maine, Massachusetts, New Hampshire, New Jersey, New York, Ohio, Pennsylvania, Rhode Island and Vermont.

If you are outside any jurisdiction that will take you — a common situation for people already travelling — the real cost is a flight and a hotel, not a visa fee. That can easily exceed the government fee several times over, and it is the single most under-budgeted line item in this process. It also matters that the DTV must be applied for from outside Thailand. Filing from inside the country results in refusal, and the fee is gone.

Payment mechanics add a small amount

Washington DC states that visa fees must be paid in the e-payment of the e-Visa system "by using a credit card only." Paying a foreign-currency fee by card normally attracts your issuer's FX margin and possibly a cross-border fee. We are not going to invent a percentage — it depends on your card, not on the embassy — but budget for a small amount above the headline figure rather than exactly the headline figure.

Not every mission works this way. Dubai's published DTV document list asks for the fee in cash, in exact change, at the counter. Check what your mission actually accepts before you assume a card will work.

Non-refundable means non-refundable

Singapore's DTV page marks the fee "Non-Refundable" twice. Wellington instructs applicants to make payment for the visa fee, noting it is non-refundable. Kuala Lumpur states that the visa application fee is non-refundable. Dubai puts it as plainly as anyone: "Each applicant is required to pay a non-refundable visa fee for the visa application to be processed."

London and Washington DC say nothing about refundability on their DTV pages at all. That absence should not be read as generosity.

There is no published refund mechanism and no reliable appeal route. Applicants who are refused consistently report having to submit a fresh application and pay in full again — that is corroborated across multiple secondary sources rather than stated in those words by a government page, and we would rather tell you the status of the claim than dress it up.

The same applies to your own clerical errors. A misspelled name or a wrong passport number is not corrected in place; it is a new application and a new fee.

The cost of getting it wrong

This is where the real money is, and it is why the "cheapest" route is not always the one with the smallest sticker price.

The reason DTV applications fail is usually not the amount of money in the account. It is seasoning — whether ฿500,000 has genuinely been held, or was moved in shortly before the application. No mission publishes refusal statistics, so nobody can honestly give you a percentage; what we can tell you is that this is the failure we see most often and the one reported most consistently by applicants.

Missions generally ask for three months of statements precisely to see this. The Ministry of Foreign Affairs' own DTV checklist asks for "a copy of the bank statement for the last 3 months with an ending balance of no less than 500,000 THB". Washington DC asks for statements "for the last three months with an ending balance of no less than 500,000 THB or ($16,000 USD) for each month". Singapore asks for a balance of "at least 500,000 THB (Approximtely 20,000 SGD)" for the past 3 months. Dubai wants "an original stamped 3-month bank statement… showing a maintained balance". A borrowed balance parked for a fortnight reads exactly like a borrowed balance parked for a fortnight.

Run the arithmetic on failure:

• London: a refusal costs £300. Reapplying costs another £300. Total £600 for one visa, plus whatever you have already paid a consultant, plus three months of waiting while the balance seasons properly.
• Wellington: the same mistake costs NZ$2,000, twice.

Crypto holdings, brokerage accounts, pension pots and available credit are not accepted as proof of funds. The account must be in your own name, matching the passport exactly — a company account in your business's name fails even when you own the business outright.

The missions do not agree on what ฿500,000 is worth

A detail almost nobody publishes, and one worth real money to you:

Mission	Published equivalent of ฿500,000
Washington DC	US$16,000
Los Angeles	US$17,000
London	£11,000
Singapore	~S$20,000
Dubai	AED 50,000
Kuala Lumpur (MFA checklist)	65,000 MYR

Two US missions publish USD equivalents a thousand dollars apart for the identical baht requirement. Dubai's AED 50,000 converts to roughly US$13,600 — well below Washington's US$16,000 — for what is supposedly the same threshold. You are assessed against your own mission's published figure, in a currency that moves.

The practical advice: clear the higher of the published figures for your region and hold a buffer above it for the full three months. Sitting exactly on ฿500,000 means an ordinary exchange-rate movement can put you under on the day an officer opens your file.

Third-party costs — including the ones you may not have budgeted for

Most cost breakdowns for the DTV pad this section out. We would rather cut it back to what is real — but one item we previously played down deserves more weight, not less.

What you may genuinely pay:

• Translation or notarisation of documents: roughly ฿1,000–5,000, based on the most detailed published breakdown we found (Issa Compass). Many applicants pay nothing here, because employment letters, contracts and bank statements are already in English.
• Embassy legalisation or authentication. This is a real requirement at some missions and we were wrong to imply otherwise in an earlier version of this page. The MFA's DTV checklist asks for a foreign employment contract or employment certificate "authenticated by the embassy of the country where the company is located", and the same for the company's registration or business licence. Kuala Lumpur requires that supporting materials issued outside Thailand and Malaysia be "accompanied by certified English translations and notarized by an Embassy or Ministry of Foreign Affairs only". Dubai requires relationship documents for dependants to be "attested by the Ministry of Foreign Affairs and International Cooperation, Dubai". Fees and turnaround for that step are set by the authenticating body, not by Thailand, and vary far too much for us to quote a range. Check your mission's checklist for the word "authenticated", "attested" or "notarized" before you assume this is free.
• Health insurance: not a stated DTV requirement on any primary source we could find. Some cost guides describe it as mandatory; we do not think that is supportable. Published estimates run ฿5,000–20,000+ per year. Treat it as a living cost you would pay anyway, not a visa cost.
• Soft-power course or treatment fees: if you are applying under the Thai Soft Power category — Muay Thai, Thai culinary training, or medical treatment, generally six months or more from a registered provider — the course or treatment fee is yours to negotiate with the provider. There is no official schedule and we will not invent a range. Note that Thai language schools no longer qualify under soft power; those applicants need an ED visa, and the DTV fee spent finding that out is not refundable.

What most applicants will not pay:

• Courier fees. Where the application runs through the e-Visa portal, the process is upload-based and your passport stays with you. This is the normal case, but it is not universal: Dubai's published procedure requires personal attendance, retains the original passport during processing, and states that you "will not be able to take your passport back while your visa application is being processed." Read your own mission's page rather than assuming the digital route.

Consultancy fees — ours, and everyone else's

Here is the market as published:

Provider	Published fee	Government fee included?
Applying yourself at thaievisa.go.th	฿0	n/a — you pay it directly
Issa Compass (their survey of the market)	Agent fees ฿3,000–15,000+; preparation-only assistance from ฿9,000	Varies
Thai Visa Centre	First-time DTV from ฿8,000; extension packages ฿12,000 (existing client) / ฿14,000 (new), each including the ฿1,900 government fee; border run ฿6,500	Mixed by package
Siam Legal	US$499 Regular / US$699 Premium / US$199 per dependant — "prices do not include the government's embassy fees"	No
Siam DTV (us)	US$99 assessment, US$499 Regular, US$699 Premium, US$199 per dependant	No

You will have noticed that our headline package prices are identical to Siam Legal's. We would rather say that ourselves than have you find it on a comparison page and wonder what else we left out. On price, we are not undercutting the largest firm in this market; we are matching it.

Three things follow from that table.

First, read which fee a refund promise attaches to. Thai Visa Centre's DTV page states that "all of our DTV service fees are fully refundable if we are unable to successfully assist you in obtaining your visa," and on the same page notes that "DTV visa fees (฿9,400-฿41,100) are non-refundable, even if denied." Those two sentences are almost certainly describing service fee versus government fee, and we are not suggesting otherwise — but they sit side by side, and a hurried reader takes away "fully refundable". Whenever you see a refund guarantee, work out which of the two fees it covers.

Our own position, stated plainly: our professional fees are non-refundable once work begins, and nobody — us, Siam Legal, anyone — can refund a government fee. The money goes to the Thai government at the point of submission.

Second, nobody controls the outcome. No consultant, ours included, has any influence over a consular officer's decision. Any firm quoting you an approval rate is quoting a number that does not exist: no official approval or refusal statistic is published for the DTV. There is a widely circulated pair of percentages that traces back to a source which does not contain it. We will not reprint it, because reprinting it is how it survives.

Third, some missions do not deal with agents at all. Dubai's own document list states that the Consulate-General "has not authorized any agency or travel agents to process the Thai visa on the applicants' behalf" and that all applicants must attend in person. We are an independent consultancy. We are not a government body, we are not authorised by any Thai mission, and no consultancy is. Anyone telling you otherwise is telling you something a Thai consulate has explicitly denied.

When you should not pay us anything

If all of the following are true, you do not need a consultancy and you should not pay for one:

• You are a salaried remote employee or a straightforward freelancer with a clear contract.
• You hold ฿500,000-equivalent in a personal account in your exact passport name, and it has genuinely been there for at least three months — not moved in recently.
• You are legally resident in the jurisdiction of the mission you will apply to, and you are physically outside Thailand.
• Your documents are already in English, and your mission's checklist does not require embassy authentication of them.
• You are 20 or over, and your nationality is not one of the roughly thirty subject to enhanced scrutiny.

That case is a form, a set of uploads and a card payment at thaievisa.go.th. It costs you the government fee and an evening. Paying US$499 for it buys you a proofreader. If that is your situation, go and do it yourself — that is the honest answer and it is the one we would give a friend.

Consultancy earns its fee where the case is genuinely awkward: a company account you cannot easily unwind, income spread across several countries, a business-owner structure that needs explaining, documents that need authenticating in a third country, a dependant application sequenced after a primary approval, a nationality that triggers additional ministry clearance, or a previous refusal you now have to explain to the same mission.

Costs after you are approved

The visa fee is not the last payment.

The extension. Each 180-day entry can be extended once, inside Thailand, at an Immigration office, for ฿1,900 — the standard Thai extension-of-stay fee. We were not able to retrieve a primary immigration.go.th page confirming it specifically for the DTV this session, but Thai Visa Centre's published extension packages break out ฿1,900 as the government component, which is consistent. You will be asked to evidence your finances again. There are unconfirmed reports of some offices charging considerably more; we cannot stand those up, so treat ฿1,900 as the figure and any larger demand as something to question.

Dependants pay full freight. London publishes £300 for DTV1 (Workcation), DTV2 (Thai soft power activities) and DTV3 (spouse and children under 20 of DTV holders) alike. A family of three applying in London pays £900 in government fees, not £300 with add-ons. Dependants also apply separately, after the primary applicant is approved. Our US$199 per dependant sits on top of that government fee, not instead of it.

Banking and tax. DTV holders frequently cannot open Thai bank accounts, and some existing accounts have been closed. And spending 180 days or more in Thailand in a calendar year makes you a Thai tax resident — which, given the visa grants 180 days per entry with an extension available, is a realistic outcome rather than an edge case. Neither is a fee, but both are financial consequences worth pricing into the decision.

Timing, honestly

There is no single official processing time for the DTV. Individual missions publish their own guidance, and it is not even measuring the same thing from one to the next:

• Dubai states the visa process "takes 2 working days from the date that the applicant submits all required documents."
• Wellington states it takes "around 5-10 working days to process the visa applications" — general guidance, not DTV-specific.
• Kuala Lumpur asks applicants to apply "at least 15 working days before the intended date of travel."
• Singapore asks applicants to complete the application "at least 21 working days before the intended date of travel."

Note that the last two are advance-notice instructions, not processing estimates. Anyone who lines these up into a single "DTV processing time" range is comparing unlike quantities. Any page quoting you "5 to 10 business days" as a universal rule is guessing.

Check your own mission's page and add margin. Booking flights before a visa is issued is a cost of getting it wrong that does not appear on any fee schedule.

If your case is the straightforward one described above, apply yourself and keep the money. If it is not, our US$99 eligibility assessment is credited in full against any package taken within 90 days — including when the assessment concludes you should simply file it yourself.

CORRECTIONS MADE

1. "No primary source specifies apostille or legalisation for the DTV" — false. Major. This was the most serious error, because it told readers not to budget for a cost that is officially required. The MFA's own DTV checklist requires the employment contract/certificate and the company registration to be "authenticated by the embassy of the country where the company is located." Kuala Lumpur requires materials issued outside Thailand and Malaysia to be "notarized by an Embassy or Ministry of Foreign Affairs only." Dubai requires dependant relationship documents "attested by the Ministry of Foreign Affairs and International Cooperation, Dubai." Moved from "you very likely will not pay" to "you may genuinely pay," with the sources quoted and no invented cost range.

2. "Courier fees. The e-Visa system is upload-based. Your passport does not travel." — not universally true. Dubai's published DTV document list requires in-person submission and states the applicant "will not be able to take your passport back while your visa application is being processed." Rewritten as the normal case with the exception named.

3. Washington DC and New York jurisdiction — the article claimed no primary table could be reached. Both are documented. DC covers 15 jurisdictions (13 states plus DC and Puerto Rico); New York covers 10. Replaced the hedge with the actual lists. Declining to state a verifiable fact is as much an accuracy failure as stating a wrong one.

4. Age threshold: "You are over 20" → "You are 20 or over." The minimum age is 20. As written, the checklist wrongly excluded 20-year-olds from the do-it-yourself case.

5. The "62–94%" figure was printed in full, immediately followed by "We do not repeat it." Self-contradictory, and reprinting is exactly how a bogus statistic propagates. Removed the number; kept the debunk.

6. Fabricated quotation from Singapore. The article quoted "THE VISA FEE IS NON-REFUNDABLE." as appearing in capitals. The page marks the fee "Non-Refundable" twice with asterisks; that sentence does not appear. Corrected to describe what the page actually says. Added genuine non-refundability quotes from Kuala Lumpur and Dubai.

7. Internal arithmetic contradiction in the fee cluster. The table gave London ~US$380–400 and Singapore ~US$370–390, then the text claimed all three "cluster tightly around US$390–405" — a range Singapore's own row falls below. Harmonised to "broadly between US$370 and US$410," with London's row corrected to ~US$390–405.

8. "It varies by a factor of four" — comparing unlike quantities. Singapore's "21 working days" is an apply-ahead instruction; Wellington's "5–10 working days" is a processing estimate. Dividing one by the other is not a spread. Added Kuala Lumpur (15 working days, advance notice) and Dubai (2 working days, processing) and flagged explicitly which type each figure is.

9. Los Angeles "thirteen states and territories" followed by a list of 13 states plus territories. The count and the list disagreed. Reworded to "thirteen states plus the US Pacific Territories" and alphabetised.

10. Seasoning framed as a hard statistical fact. "The most common reason DTV applications fail" implies refusal data that does not exist. Reframed as what we see and what is consistently reported, with the absence of official statistics stated — consistent with the article's own position two sections later.

11. "Missions ask for three months of statements" → "generally ask." Los Angeles's published wording asks for "a recent saving or checking bank statement with an ending balance," not explicitly three months. The generalisation was slightly too strong.

12. Thai Visa Centre extension packages mis-described. The article implied the ฿1,900 government fee was included only in the ฿14,000 new-client package. TVC's page breaks out ฿1,900 in both (฿12,000 = ฿1,900 + ฿10,100; ฿14,000 = ฿1,900 + ฿12,100). Corrected.

13. Health insurance characterisation. Kept the article's correct position that insurance is not a stated DTV requirement, but made explicit that this contradicts the cited source (Issa Compass calls it mandatory), rather than silently citing that source's number while rejecting its claim.

14. Tokyo JPY 52,000. Verified as far as possible: it appears only on aggregator sites, not the embassy's own pages. The article's hedge was correct and is retained, with slightly firmer wording.

Claims verified as correct — changed only where noted

Wellington NZ$2,000 per person (confirmed on the embassy's own visa types page, alongside LTR at NZ$6,000 — this is real, not a typo); NZ/Cook Islands/Samoa/Niue restriction; London £300 across DTV1/2/3 and £11,000 equivalent; DTV1/2/3 category mapping; Washington DC US$400 and the exact "$16,000 USD for each month" wording; DC credit-card-only e-payment; Los Angeles US$17,000 and no published fee; Singapore S$500, ~S$20,000, citizen/resident restriction, 21 working days; Phnom Penh publishing no fee; Siam Legal's US$499/US$699/US$199 and its exclusion of government fees; Issa Compass's ฿1,000–5,000 and ฿3,000–15,000+ ranges; TVC's ฿8,000 / ฿6,500 / "฿9,400-฿41,100" figures and refund wording; the ฿500,000 threshold and 3-month statement rule; ฿1,900 extension; £900 for a family of three; 180-day tax residency; the no-approval-rate and no-official-processing-time positions.

One thing I could not resolve

The Dubai document list is undated and describes a wholly in-person, cash, passport-surrendered process, which sits oddly against the e-Visa portal being the stated route. It may be partly superseded. I have used it only for claims where being out of date would not mislead (the AED 1,500 fee, the AED 50,000 equivalent, the attestation requirement, the "no authorised agents" statement), and I have flagged the in-person procedure as a mission-specific exception rather than presenting it as the current universal position. Worth a re-check against Dubai directly before this page goes live.
