Types of Visa in Thailand: Pick Your Route by Purpose

Choose a Thailand visa by the purpose of your stay: tourism, transit, work or business, study, family, retirement, specialist work, or another official category. The Ministry of Foreign Affairs recognises 6 core visa types, and the official e-Visa portal groups applications by purpose, covering tourism, transit, work and business, study, family, retirement and specialist routes like DTV, SMART and LTR. This guide to the types of visa in Thailand separates exemptions from real visas, explains the Non-Immigrant codes, and links to our detailed guides for each route. If you already know you are coming as a tourist, start with our tourist visa guide.

Visa Exemptions Are Not Visas

A visa exemption is permission to enter Thailand without a visa, not a type of visa. The distinction matters because many travellers assume they hold a visa when they have actually entered under an exemption scheme. Thailand is scheduled to revise its visa-exemption and Visa on Arrival schemes from 15 September 2026, while other visa categories will not be affected by that change. If you read advice published before that date, treat the exemption details as potentially outdated.

An extension is a 3rd, separate thing. Extending your permitted stay changes how long you can remain in Thailand, not which visa category you are in. Our Thailand visa extension guide covers that process. Because exemption durations and eligible nationalities depend on current rules, confirm your own situation on the official portal before you travel.

The 6 Core Types of Visa in Thailand

The Ministry of Foreign Affairs lists 6 core visa types Thai missions may issue: Transit, Tourist, Non-Immigrant, Diplomatic, Official and Courtesy. That list is the formal backbone of the whole system.

Treat these 6 types as a map, rather than as a complete eligibility guide. The map tells you which broad branch to inspect, but it does not settle whether you qualify, how long you may stay, or which documents your responsible mission will request. Those details depend on the route and your circumstances. This distinction prevents a common mistake: finding a familiar visa name online and assuming every mission applies the same checklist to every applicant.

Diplomatic, Official and Courtesy visas are issued to specific official roles, so most readers only need to compare Transit, Tourist and Non-Immigrant. We deliberately avoid informal labels like marriage visa, because they do not appear in the official category list.

In everyday conversation, people often use convenient names such as business visa, education visa or retirement visa. Those labels help describe the purpose, but the application usually sits under a formal Non-Immigrant code. Use the plain-language label to understand the route, then confirm the exact code and purpose shown by the official portal. If 2 routes sound similar, the deciding factor is the activity you will actually carry out in Thailand, not the name that seems closest.

Non-Immigrant Visas: Purpose Maps to a Code

Non-Immigrant subcategories map your purpose to a code, including B for business or work, ED for study, and O for purposes such as family or retirement. Once you can read these codes, Thai immigration paperwork becomes much less mysterious.

The ED code is the study route, and it is the category our school files applications for when students enrol to study Thai. Note that a visa and a work permit are different documents: the B code covers the visa side, while the work permit is handled separately, as our work permit guide explains.

Specialist Long-Stay Routes: DTV, LTR and SMART

Thailand runs 3 specialist routes with distinct purposes: the DTV for workcation and soft-power activities, the 10-year LTR programme, and SMART Visa routes. These programmes are often confused with each other, so a quick comparison helps.

The DTV is aimed at people combining remote-style work with longer stays, while the LTR programme targets defined long-term resident groups with a 10-year horizon. SMART routes cover qualifying talent, investors, executives and startups. Eligibility details, financial thresholds and document requirements for each route sit with the responsible authority, so verify them on the official portals before planning around any of these programmes.

Start by comparing the qualifying purpose, not the possible length of stay. DTV, LTR and SMART are separate programmes with different audiences and responsible authorities. A long validity period does not make 1 route interchangeable with another.

Check whether your real activity matches the programme first, then review its current eligibility and evidence requirements. This order saves time because it filters out unsuitable routes before you collect documents or make plans based on benefits you may not qualify for.

How to Choose Your Route in 3 Steps

Choose your route by naming your single main purpose, matching it to a category, then verifying it on the official e-Visa portal. The method matters more than memorising the list, because purpose drives every later decision.

Step 1: Name your main purpose in 1 phrase. Tourism, study, work, family, retirement or a specialist route. If you have more than 1 purpose, or you are unsure which category fits, verify the applicable route with the official portal or the responsible Thai mission before you plan further.

Step 2: Match the purpose to a category. First ask whether an exemption covers your trip at all. If not, use the tables above. Short tourism trips point to the Tourist type, while remote work or specialist careers may point to DTV, LTR or SMART.

If your stay length is uncertain, confirm the correct category with the official portal rather than assuming a code. If study is your purpose, our ED Visa guide explains that route in detail.

Step 3: Verify on the official e-Visa portal. The portal groups applications by purpose, so you can confirm the exact category, fees and documents for your situation before applying. The official e-Visa process has 6 stages: account, application form, supporting documents, fee, processing and email confirmation. Working through the portal helps you confirm the relevant application path before you check the specific requirements for your situation.

Before you submit, make a short decision record for yourself: your main purpose, the category selected, the official page used, and the date you checked it. Then compare every document you prepare with the instructions for your responsible mission. Keeping that record makes it easier to notice when advice from a forum, old article or agent conflicts with the current official route. If the sources disagree, stop and verify with the official portal or mission before paying a fee.

Where to Verify Your Visa Category

Check your exact category, fees and document requirements on the official e-Visa portal at thaievisa.go.th, because eligibility depends on the applicant and the responsible Thai mission. We do not print universal document lists or financial thresholds here for the same reason: a requirement that fits one nationality, purpose or mission can be wrong for another, and outdated lists cause real problems at application time.

Our detailed guides cover the routes most readers end up comparing: the tourist visa, the education visa and ED Visa pages, the retirement visa, the work permit and the visa extension guide. Use this page to choose the category, then use the dedicated guide for the procedure. And if you want to study Thai in Bangkok, explore ED Visa study options to see how our school supports that route.

Thailand Visa Types: Frequently Asked Questions

Which Thai visa is for tourism?

The Tourist visa is the core Ministry of Foreign Affairs visa type for tourism, and tourism also appears as a purpose group on the official e-Visa portal. Some short leisure trips may instead qualify for a visa exemption, which is entry without a visa rather than a visa category. Our tourist visa guide explains the tourist route in detail.

Which visa is used for studying in Thailand?

Study purposes use the Non-Immigrant ED code, the subcategory that maps education to a visa category. Our education visa guide and ED Visa page cover the process, and we file ED applications for eligible students who study Thai with us.

Is a visa exemption a type of visa?

No, a visa exemption is permission to enter Thailand without a visa, not a type of visa. Thailand is scheduled to revise its visa-exemption and Visa on Arrival schemes from 15 September 2026, and other visa categories will not be affected by that change. Because exemption rules shift over time, verify your nationality’s current position on the official portal before travelling.

Where should I check the exact requirements?

Check your exact category, fees and document requirements on the official e-Visa portal at thaievisa.go.th. Requirements depend on the applicant and the responsible Thai mission, so no single universal list is reliable for everyone. The portal groups applications by purpose, which makes it the fastest way to confirm you are applying under the correct category.
