Thailand has a visa for almost every reason you might want to be here — working remotely, taking a job with a Thai employer, retiring, joining a Thai spouse, or building a company. The hard part is not finding options. It is working out which one you actually qualify for, and what each one asks of you once you have it.
This guide walks through the main long-stay routes: the Destination Thailand Visa (DTV), the Non-Immigrant B (Non-B) work visa, the Long-Term Resident (LTR) visa, the SMART Visa, and the Non-Immigrant O (Non-O) family of visas. For each one we cover who it is for, what you need to qualify, and how long it lasts.
Destination Thailand Visa (DTV)
The DTV is Thailand's visa for remote workers, freelancers, and people coming to take part in Thai cultural activities. It is the newest of the long-stay options and, for people who earn their living from a laptop, usually the simplest.
Key facts:
- Validity: 5 years, multiple-entry. The five years run from the date the visa is issued, not from your first entry.
- Stay per entry: up to 180 days. Leave and re-enter to start a fresh 180-day stay. An in-country extension of another 180 days exists on paper, but it is frequently refused, so plan around a border trip rather than relying on it.
- Financial requirement: THB 500,000 in personal savings, held for three months.
- Minimum age: 20. Under-20s can only be included as dependants.
- Dependants: your spouse, or children under 20, can apply — each as a separate application, submitted after the main applicant is approved.
Who qualifies:
- Remote workers and freelancers: employed by or contracting with a company outside Thailand.
- Soft-power participants: people enrolled in qualifying Thai activities such as Muay Thai training or Thai cooking courses.
One important restriction: the DTV can only be applied for from outside Thailand, through the Thai e-Visa system, and you must apply in the country where you hold citizenship or legal residence. Applying from a third-country hub while travelling is no longer an option.
How Issa helps:
- Eligibility check first: we confirm your savings history and qualifying activity before you spend anything on an application.
- Embassy-specific guidance: requirements and processing times vary by embassy, and we tell you what yours expects.
- Document review: our legal team checks every file before submission, which is where most avoidable rejections come from.
Non-Immigrant B (Non-B) Visa
The Non-B is the standard route for foreigners taking a job with a Thai employer or conducting business in Thailand. It is the visa half of a two-part credential — the visa lets you stay, and the work permit lets you work. You need both.
How the process runs:
- Your employer applies first: they file a WP32 pre-approval letter through Thailand's e-work permit system.
- You apply from outside Thailand: with the WP32 letter, you apply at a Thai embassy through the e-Visa portal and receive a 90-day single-entry Non-B.
- Work permit in Thailand: after you arrive, you complete a medical check and your employer finalises the work permit. You can start working as soon as the work permit is approved.
- One-year extension: once the work permit is issued, you extend the visa at immigration for a year, renewable annually.
What your employer must meet:
- Four Thai employees for every foreign employee
- THB 2,000,000 in registered capital per foreign employee
- VAT registration, and at least three months of social security (SSO) contributions for those Thai staff before the application
Two things catch people out. First, the 90-day Non-B is single-entry: if you leave Thailand before the one-year extension is stamped, you need a re-entry permit or the visa is cancelled when you exit. Second, your passport should have more than 18 months of validity left before the Non-B is issued, because visa validity is capped at your passport's expiry date and a shorter passport means a shorter extension.
How Issa helps:
- Employer-side checks: we confirm your company meets the capital, staffing, and SSO requirements before anyone files.
- Coordinated timeline: the WP32, the embassy application, and the work permit have to happen in order, and we keep the sequence on track.
- Extension support: the one-year extension needs a substantial employer document pack, and we prepare it with your company.
Long-Term Resident (LTR) Visa
The LTR is Thailand's ten-year visa, issued as an initial five years plus a five-year extension. It is administered by the Board of Investment (BOI) rather than immigration, and it comes with meaningful quality-of-life benefits: annual reporting instead of 90-day reporting, multiple-entry as standard so no re-entry permits, fast-track lanes at the airport, and a foreign-sourced income exemption.
It is a two-stage process. BOI reviews your qualifications and issues an endorsement — roughly two months — and the visa itself is issued afterwards, either in Bangkok or at a Thai embassy overseas. Expect around four months end to end.
Categories of LTR Visa:
- Wealthy Global Citizen: USD 1,000,000 in global assets, of which at least USD 500,000 must be invested in Thailand through property, Thai company shares, or Thai government bonds. A bank deposit alone does not count as the Thailand investment.
- Wealthy Pensioner: aged 50 or over, with USD 80,000 a year in passive or unearned income — or USD 40,000 to 80,000 a year plus USD 250,000 invested in Thailand. Employment income does not qualify; the income has to be genuinely passive, such as a pension, dividends, or rental income.
- Work-from-Thailand Professional: for remote employees of a qualifying foreign company. USD 80,000 a year in income, or USD 40,000 to 80,000 plus a Master's degree, intellectual property ownership, or Series A funding of at least USD 1,000,000.
- Highly Skilled Professional: for experts employed by or serving companies in BOI-targeted industries in Thailand. USD 80,000 a year, or USD 40,000 to 80,000 plus a relevant Master's degree.
Every category also requires health coverage or savings: health insurance covering at least USD 50,000, current Thai social security benefits, or USD 100,000 held in your own bank account for at least 12 months.
Work rights differ by category, and this is the detail most often misunderstood. Work-from-Thailand Professionals cannot obtain a Thai work permit — the category is for remote work for a foreign employer only. Wealthy Pensioners are not permitted to work by default. Wealthy Global Citizens and Highly Skilled Professionals can pursue a digital work permit where their employer qualifies.
Dependants:
- Spouse and children under 20 can join you, up to four dependants per main holder.
- Each dependant files a separate BOI application, and all of them must collect the visa in the same location as the main applicant.
How Issa helps:
- Category matching: the difference between qualifying and not often comes down to which category you file under, and we work that out before you apply.
- Evidence that BOI accepts: asset and income documents have to be evidenced in specific ways, and we tell you exactly what to produce.
- Two-stage tracking: endorsement and issuance each have their own deadlines, and we manage both so nothing lapses.
SMART Visa
The SMART Visa was designed to bring skilled people and investment into Thailand's targeted industries. The programme has since been narrowed, and two categories remain available: SMART S for startup founders and SMART O for their dependants. Older guides describing a wider set of SMART categories no longer reflect what the Thai government issues.
SMART S (Startup):
- Validity: two years from the start, renewable — there is no 90-day-then-extend cycle.
- Company requirement: you must already have a registered Thai company in a targeted industry, and be either a director or hold at least 25% of the registered capital.
- Financial requirement: THB 600,000 in your personal savings or checking account, held for the last three consecutive months.
- Timeline: one to three months, in two stages — endorsement first, then visa issuance in Thailand or at an embassy overseas.
Why founders choose it:
- No work permit required: which also removes the minimum salary requirement, the 4:1 Thai-to-foreign staffing ratio, and the THB 2,000,000 registered capital rule that a Non-B would impose on your company.
- Annual reporting: 90-day reporting is replaced by a yearly check-in. Separately, all SMART Visa holders file a status report with the SMART Visa Unit each September.
- No re-entry permit needed, plus fast-track immigration lanes at the airport.
Dependants (SMART O):
- Your spouse and children qualify under SMART O, tied to the same validity period as your SMART S.
- Spouses on SMART O may work without a separate work permit, in occupations not otherwise restricted to Thai nationals.
Targeted industries include digital, next-generation automotive, smart electronics, medical and wellness tourism, agriculture and biotechnology, automation and robotics, aviation and logistics, alternative energy, and human resource and education development.
How Issa helps:
- Honest screening: the criteria the endorsing agencies apply to a company are not published in detail, so we give you a realistic read on your chances before you commit.
- Application materials: pitch deck, company profile, and business progress report are all part of the submission, and we prepare them with you.
- Ongoing obligations: annual reporting and the September status report are easy to miss, and we track both.
Non-Immigrant O (Non-O) Visa
The Non-O covers people whose reason for being in Thailand is personal rather than commercial — retirement, marriage to a Thai national, raising a Thai child, or joining a family member who already holds a Thai visa. All of these follow the same shape: a 90-day entry, then a one-year extension granted in Thailand, renewed annually.
You can apply for the initial 90-day visa at a Thai embassy before you travel, or convert from an eligible visa while you are already in Thailand. The embassy route means one immigration visit later for the extension; converting in-country means three, and a much larger document pack.
Types of Non-O Visas:
- Retirement: for applicants aged 50 or over. You need THB 800,000 in a Thai bank account seasoned for three months, or a monthly pension of THB 65,000, or a combination of THB 400,000 in savings plus THB 40,000 a month in income.
- Marriage: for foreigners legally married to a Thai national. THB 400,000 in savings, or THB 40,000 or more per month in income if you hold a work permit.
- Parent of a Thai child: for a foreign parent of a Thai national child, on the same financial thresholds as the marriage visa.
- Dependants: spouses and children of Non-B holders and of retirement visa holders can apply. Dependants of a Non-B holder have no financial requirement of their own — eligibility rests on the main holder's employer.
A note on the retirement route: the standard THB 800,000 path described above is a Non-O Retirement visa. The Non-OA is a different product — a one-year multiple-entry visa issued abroad that additionally requires health insurance, a medical certificate, and a criminal record check. The two are often confused, and they are not interchangeable.
How Issa helps:
- Seasoning and timing: funds have to sit in the right account for the right length of time, and getting this wrong costs months. We map the dates with you.
- Embassy versus conversion: we walk you through which path suits your situation and what each involves.
- Renewals: the annual extension has its own requirements, and we handle them each year rather than leaving you to rediscover them.
Choosing between them
As a rough guide: if you work remotely for a foreign employer, start with the DTV, and look at the LTR Work-from-Thailand category if your income is high enough to justify a ten-year visa. If a Thai company is hiring you, it is a Non-B. If you are over 50 with savings or a pension, it is a Non-O Retirement, or an LTR Wealthy Pensioner at higher income levels. If you are married to a Thai national or have a Thai child, the Non-O covers it. If you already own or direct a Thai company in a targeted industry, SMART S avoids the work-permit machinery entirely.
The right answer usually depends on details that are specific to you — how your income is structured, how long your money has been where it is, which passport you hold, and where you will be when you apply. Issa Compass takes you from that first question through document review to an approved visa, with a legal team checking your file before it reaches an embassy. Find the visa that fits your situation.
