The Non-Immigrant ED (education) visa lets you stay in Thailand to study, including short courses in the Thai language. For a language course, the school must provide an enrolment letter and a letter from the relevant authority under the Ministry of Education; the visa is single entry, valid for three months, and each stay on arrival is up to 90 days, with any extension at the discretion of immigration (as of October 2026).
For people who want to learn Thai properly, rather than pick up phrases on holiday, the ED visa is the traditional route. It ties your stay to a real course at a school that the education authorities recognize. It is not a work visa, and it does not let you stay without studying: the visa stands or falls with the school's paperwork and your enrolment.
This page explains how the ED visa works for language students, what to ask a school before you pay, and how it compares with the Destination Thailand Visa. We read the government's e-Visa portal and the ED page of Thailand's embassy in Norway on 2 October 2026. Each embassy adds its own details, so your own embassy's page has the last word.

What the ED visa covers
"ED" covers every kind of study in Thailand, not only language schools. The Oslo embassy lists study, study or observation tours, projects and seminars, internships, conferences and training courses, and study as a foreign Buddhist monk. On the e-Visa portal the ED visa is split into categories, each with its own document list:
- a short course in the Thai or English language, or Muay Thai training;
- elementary or secondary school;
- a bachelor's degree or higher;
- vocational, technical or diploma study below bachelor level;
- workshops run by government bodies, foreign missions or international organizations;
- Dharma study for monks, nuns and priests (with a letter from the National Office of Buddhism);
- curricular internships and exchange students.
Thai-language students use the first category. Boxing students share that category, with the Sports Authority of Thailand in place of the education letter; choosing a Muay Thai camp is a separate subject on this site.
Choosing a school: what "accredited" really means
You will see language schools advertise themselves as "accredited" or "ED visa approved". The official requirement is narrower than either phrase. The portal wants two letters: one from an authority under the Ministry of Education, and one from the school confirming that you are enrolled, signed by someone entitled to sign for it, together with a copy of that signatory's ID or passport.
In practice, that means the school must be one the education authorities will issue a letter for, which for a private language school generally means a school licensed under the Ministry of Education. A school without that standing cannot give you what the portal requires. We could not find a public, official list of approved Thai-language schools, so ask the school directly:
- Can you provide both the enrolment letter and the Ministry of Education letter for an ED visa, and how long do they take?
- How many hours a week is the course, and over how many months?
- What documents do you provide later for extensions of stay, and is there a fee for them?
- What happens to my fees and my visa if I stop attending or leave early?
Get the course length, weekly hours and total price in writing before you pay. A school that promises a visa with little or no study is offering you a risk, not a service, because immigration decides on extensions and can refuse them.
Documents for a language-course ED visa
The e-Visa portal lists these for the "short course (Thai or English language)" category:
- your passport;
- a recent photo;
- a document that shows your current location, such as a residence permit or visa for the country you are applying from;
- proof that you can pay tuition and live during the course, as three months of statements or a sponsorship letter, with no minimum stated for this category;
- the Ministry of Education letter;
- the school's enrolment letter, signed by an authorized person, with a copy of their ID or passport.
Embassies add their own requirements. The Oslo embassy's ED page, for example, asks for flight tickets into and out of Thailand, funds of 20,000 baht per person or 40,000 baht per family, an official note certifying the purpose of travel, and a health policy worth at least USD 50,000 that covers all treatment, COVID-19 included. That page dates from 2021 and the insurance line may be a pandemic-era rule that the portal no longer lists, so check with your own embassy. Oslo charges 800 Norwegian kroner for the single-entry visa; other embassies set their own fees.
The portal routes your application to the embassy for your country of residence, and it does not accept applications from people already in Thailand.
Staying longer than 90 days
The ED visa is single entry, and each arrival gives a stay of up to 90 days. A language course longer than that requires an extension of stay at an immigration office. No extension is automatic; in the Oslo embassy's words, the decision rests with the immigration officer alone.
How long each extension lasts for language students, and what immigration checks before granting it, is not set out on any official page we found. Ask the school which letters it provides for each extension and what its students have needed recently, and apply before your current stay ends; letting it lapse makes you an overstayer, with the fines and bans described in our guide to overstaying in Thailand.
Two routine duties come with any long stay. After 90 days in the country without leaving, an address report is due; see our guide to 90-day reporting. Your landlord files the TM30 residence notification, which immigration may check when you extend; our tenant's guide explains what to ask the owner for. Leaving Thailand during the course ends a single-entry stay unless you have a re-entry permit, so plan trips home around term breaks and ask immigration first.
Part-time work is not allowed on an ED visa. A student visa carries no right to take paid work, and Thai law demands a work permit for any job, whether it is tutoring, a café shift or freelance work for Thai clients. A job means switching to the employer-sponsored route explained on our page about the Non-B visa and work permit.
The ED visa or the DTV?
Since 2024 the Destination Thailand Visa has been the other long-stay option for people who come to learn something. Its rules are on its own page; the short comparison is this:
| ED visa (language course) | DTV | |
|---|---|---|
| Built on | Enrolment at a school with a Ministry of Education letter | Remote work, or a "soft power" activity like Muay Thai or Thai cooking |
| Money shown | Enough to cover tuition and living costs (no fixed sum on the portal) | 500,000 baht balance over three months |
| Entries and stay | Single entry; up to 90 days, then extensions at immigration's discretion | Multiple entry for 5 years; 180 days per entry, extendable once |
| Main commitment | Real study at the school | Meeting the DTV conditions and documents |
The DTV portal page names Muay Thai, Thai cooking and medical treatment as examples of soft-power activities; it does not name language study. If you hope to study Thai on a DTV, ask the embassy where you apply whether it accepts a language course before you pay for one.
Budgeting for a year of study
We do not print tuition figures, because no official source publishes them and schools price courses in very different ways. Ask several schools for the full cost of a year: tuition, registration, books, and any charge for visa letters and extension documents. Add the visa fee at your embassy and the extension fees at immigration; Bangkok Immigration's general extension fee was 1,900 baht in its 2024 fee list.
Living costs depend on the city; a resident's monthly budget can be built from official tariffs and your rent. Many Thai-language students base themselves in Bangkok or Chiang Mai, which both have several language schools to compare. Health insurance is worth having even when your embassy does not require it; see health insurance for expats.
What learning Thai involves
Thai is a tonal language with its own alphabet, and a structured course usually teaches reading and writing alongside speaking. That is the main difference from the survival Thai most visitors use. Our older article of Thai phrases for travelers covers greetings, numbers, food and getting around; a course goes on from there to tones, the script and grammar, which take months of regular practice.
If you are not sure a long course is for you, try a few weeks of lessons on a visit first. The visa exemption gives many passport holders, including most Europeans, Americans, Singaporeans and Malaysians, 30 days, which is enough to tell whether you want to commit to an ED visa.
Frequently asked questions
Can I get an ED visa for any Thai language school?
No. Besides the school's enrolment letter, the e-Visa portal requires a letter from an education authority under the Ministry of Education. Only schools that can obtain that letter can support an ED visa, so ask before you pay any fees.
How many days does a language-school ED visa give?
Each entry gives up to 90 days. Longer courses need extensions of stay at an immigration office, which are granted at the officer's discretion. Official pages do not publish a fixed cycle, so ask your school what documents recent students needed.
Can I work part-time while studying Thai on an ED visa?
No. A student visa comes without a work permit, and without one no job in Thailand is legal, including private tutoring and online work for Thai clients. Paid work means changing to an employer-sponsored visa.
Is health insurance required for a Thai ED visa?
The e-Visa portal's language-course category does not list health insurance. Some embassy pages do, such as Oslo's, which asks for USD 50,000 of cover. Check your embassy's page, and consider insurance anyway, because Thai hospitals expect a guarantee of payment.
Is the ED visa or the DTV better for learning Thai?
The ED visa is built for study at a recognized school and needs no fixed savings figure. The DTV gives longer stays but needs a 500,000-baht balance and does not name language study as an activity. Ask your embassy which it accepts for your plans.
