If your Thailand visa was refused, no embassy or consulate publishes a procedure for appealing that decision. The practical route is to fix your file and submit a new application with a new fee; the fee for the refused application is not returned. A visa refusal, a refused entry at the border and a refused extension inside Thailand are three separate decisions, each with its own rules. Section 22 of the Immigration Act gives a right of appeal against a refused entry, with some exceptions; for visa refusals, missions publish no equivalent procedure.
In short
- A visa is granted or refused by an embassy or consulate; entry is decided by an immigration officer at the border; an extension of stay is decided by the Immigration Bureau — three different decisions.
- No Thai mission publishes an appeal procedure for a refused visa.
- Whether you get a reason depends on the mission: some give one, others reserve the right not to.
- Reapplying means paying the fee again; no mission publishes a waiting period.
- Section 22 of the Immigration Act lets you appeal a refused entry to the Minister of Interior within 48 hours, with a couple of exceptions.
Why Thai visas are refused
Each Thai mission decides a visa application at its own discretion. There is no single published list of grounds for refusal, so the refusal letter itself is worth reading closely: some missions name the reason, others do not.
It also helps to separate a refusal from a cancellation. A rejection means the mission declined the application; it may relate to eligibility, incorrect information or the documents submitted. An application may be cancelled, for example, if requested documents are not supplied by the mission's deadline: embassies in Moscow and Lima, and the consulate-general in Sydney, give applicants 45 days for this. These are different outcomes, and knowing which one applies to you matters before you reapply.
False information in an application carries heavier consequences than an ordinary refusal. The Royal Thai Embassy in London warns that inaccurate information in a DTV application may lead to a future prohibition of entry; the embassy does not explain the mechanism behind that warning.
Can a refusal be challenged
Three different bodies make these three decisions, and the right to challenge each one is different too.
| Decision | Who decides | Can it be appealed | What to do |
|---|---|---|---|
| Visa refused | Embassy or consulate | Missions publish no procedure | New application with a new fee |
| Entry refused at the border | Immigration officer | Yes, appeal to the Minister within 48 hours (with exceptions) | Ask the officer how to lodge the appeal; the clock is 48 hours |
| Extension of stay refused in Thailand | Immigration Bureau | The Act gives no appeal | Ask Immigration what the decision was based on and what your options are |
A visa refusal is the mission's own decision, and no official review process for it has been published. A visa in any case does not guarantee entry: the Royal Thai Embassy in Helsinki says so directly, because entry is decided separately, by an immigration officer at the border.
Section 22 of the Immigration Act B.E. 2522 specifically covers a refused entry: a foreigner ordered to leave may appeal to the Minister of Interior within 48 hours of learning of the order. Two grounds are excluded from this right: not holding a valid passport or visa (section 12(1)) and a ministerial entry ban (section 12(10)). The Minister's decision is final.
A refused extension of stay inside Thailand is a third, separate case: the Immigration Act gives no appeal procedure against it. After a refusal like this, we recommend asking the immigration office directly what the decision was based on, whether anything can still be added to the file, and on what basis you may remain in the country; our guide to visa extension support in Phuket covers what each category typically needs to show.
One more point worth a mention: in case A.696/2561, Thailand's Administrative Court quashed a deportation order against a Phuket resident. That was a challenge to a deportation order, not a visa refusal, and the Administrative Court is not a general route against a refused visa.
Send us the mission's letter and a list of what you submitted — our lawyers will review what may have caused the refusal and what to change in a new application.
Reapplying: when and where
A new application goes through the same official e-Visa portal, thaievisa.go.th, and carries a new government fee. No mission publishes how long to wait before reapplying: it makes more sense to apply once you understand what went wrong and have fixed it, rather than resubmitting the same file the next day.
You apply at the mission covering your place of residence, following that mission's own requirements.
DTV is a case apart. From 31 August 2026, you may only apply at a mission in the country where you are a national or a permanent resident, and a police clearance certificate is now mandatory. The requirements are set out in full on our DTV visa support page, and a DTV refused over a bank statement is a typical scenario assembled from practice, showing what reapplying can look like.
A note for applicants from the US, the UK and Australia
The missions you deal with set their own practice, and it is worth knowing where you stand before you reapply. The Royal Thai Consulate-General in Hong Kong says applicants are notified of the reason for a rejection; the embassies in Kuala Lumpur and Lima state the opposite, that they may refuse an application without giving reasons. If you applied from a UK address, the Royal Thai Embassy in London's warning about false information applies to you directly. None of this changes the basic path: Thai missions publish no appeal procedure for visa refusals, so reapplying with a corrected file and a new fee is the practical route, whichever mission you use.
e-Visa, Non-O and tourist refusals compared
Since 1 January 2025, every Thai diplomatic and consular mission processes applications through the e-Visa system, tourist and Non-Immigrant categories included.
The document requirements for each category — study, work, marriage to a Thai national, retirement and others — are set by the individual mission, and there is no single list that covers every case. Our overview of Thailand visa options compares the categories, and the retirement visa guide covers Non-O, O-A and O-X specifically.
So there is no single answer to "what happens after a Non-O refusal" versus "what happens after an e-Visa refusal": the steps are the same — new application, corrected file, new fee — while the exact documents you need depend on the category and the mission.
What to fix in the file
We start by reading the mission's letter for any explanation or document requests, then compare the submitted file with that mission's requirements. Before you reapply, we recommend working through five points.
- Read the mission's letter carefully to see whether it is a refusal on the merits or a cancellation for missing documents — the fix is different for each.
- Match your file against the requirements of your own mission, not a generic list found online: document requirements differ between embassies.
- Check your bank statements and the validity dates on certificates; an expired document is unlikely to be accepted.
- Clear up any mismatch between the application form and the supporting documents — a name spelled differently, dates that don't line up, conflicting details.
- Never include anything inaccurate: the Royal Thai Embassy in London warns this can lead not only to a refusal but to a future entry ban.
Our lawyers check a file against the specific mission's requirements and flag anything that could get a new application refused again.
What to do next
If you were refused a visa, entry or an extension, the sensible next step is to understand why before you reapply, rather than resubmitting the same file and hoping for a different result.
Our team offers a paid consultation: we go through the mission's letter, explain what may have gone wrong, and help prepare a new application. We agree the cost upfront and prepare documents in two languages. If your situation involves an extension of stay inside Thailand, see our visa extension support in Phuket page; if you are still working out how to stay longer than the standard period, start with staying in Thailand longer than 30 days.
