# Thailand Long-Stay Visa Ladder — Non-Immigrant B, DTV, LTR, and Smart Visa

**Country:** 🇹🇭 Thailand  
**Last verified:** 2026-05-22  
**Estimated time:** Non-Immigrant B and DTV typically process within five business days of complete e-Visa submission once the Ministry of Labour WP3 is in hand; LTR qualifications endorsement at the Board of Investment runs about 20 working days followed by 1–3 working days pre-approval, totalling roughly four to five weeks door-to-door; Smart Visa timing is governed by the Board of Investment endorsement and is not separately published on the consular surface  
**Cost:** Consular visa fees range from USD 80 (single-entry Non-Immigrant B) to USD 1,600 (Long-Term Resident Visa collected abroad); in-country LTR collection at the BOI One Stop Service Center is ฿50,000, with the LTR Digital Work Permit at ฿3,000 per year

## Required documents

- **Passport** *(หนังสือเดินทาง (Nangsue Doen Thang))*
  - Required: Original passport with at least six months remaining validity; biodata page submitted with every route's consular package and BOI endorsement application
  - Cost: Already issued
  - _Note:_ The passport is required at every stage — consular submission, BOI endorsement (for LTR and Smart Visa), port-of-entry inspection, and any in-country extension at the Immigration Bureau Suan Plu office.
- **Recent photograph** *(รูปถ่าย (Roop Thai))*
  - Required: Taken within the past six months; uploaded as a large, clear JPEG or PDF for e-Visa filings
  - Cost: Varies by photo studio
  - _Note:_ All four routes require the same recency standard. The embassy specifies JPEG or PDF for Smart Visa uploads; the other routes follow the same e-Visa portal upload format.
- **Proof of current location** *(หลักฐานที่อยู่ปัจจุบัน (Lakthan Thi Yu Patchuban))*
  - Accepted: Driving licence, utility bill, lease, bank statement, or other proof of stay at the applicant's current address in the consular district
  - Cost: Already issued
  - _Note:_ Smart Visa applications accept the document indicating current location in the same format as the other routes. The applicant should match the consular district to the proof of stay.
- **Bank statements (route-specific threshold)** *(รายการเดินบัญชี (Rai Karn Doen Banchee))*
  - Non-Immigrant B: Three preceding months at no less than USD 1,000 per month for a single applicant or USD 2,000 for an applicant with family
  - DTV: Three preceding months at no less than ฿500,000 (or USD 16,000) per month, or a sponsor letter meeting the equivalent threshold
  - LTR: Category-specific evidence — annual income statements for the past two years (Highly-Skilled and Work-from-Thailand), asset statements (Wealthy Global Citizen), pension and passive-income statements (Wealthy Pensioner), plus a USD 100,000 deposit maintained 12 or more months for the medical-financial floor
  - Smart Visa: Per Board of Investment endorsement schedule; not published verbatim on the consular surface
  - _Note:_ Each route reads the threshold as a per-month floor (DTV and Non-Immigrant B) or a maintained-balance floor (LTR deposit). Freshly funded LTR accounts do not satisfy the 12-month maintenance requirement.
- **WP3 letter (Non-Immigrant B only)** *(ใบ WP3 / ใบอนุญาตทำงาน (Bai WP3 / Bai Anuyat Tham Ngan))*
  - Required: Approval letter issued by the Ministry of Labour to the Thai employer in advance of the applicant's consular submission; the embassy preserves the form label as 'WP32'
  - Where to get: Department of Employment, Ministry of Labour — the employer files the request before the applicant approaches the consulate
  - Cost: Already issued
  - _Note:_ Internship applicants substitute the WP3 with a letter from the Thai company confirming the internship period and position. Teaching applicants additionally submit a criminal-clearance certificate from the FBI or state police issued within the prior three months.
- **Invitation or employment letter (Non-Immigrant B only)** *(หนังสือเชิญ / สัญญาจ้างงาน (Nangsue Choen / Sanya Chang Ngan))*
  - Required: Letter from the Thai employer naming the applicant, the purpose of visit, and the length of stay; signed by an authorised company representative
  - Cost: Already issued
  - _Note:_ Business-visitor sub-band (meetings, exhibitions) submits an invitation letter from the host company; employment sub-band submits the signed employment letter.
- **Eligibility evidence (DTV track-specific)** *(หลักฐานการมีคุณสมบัติ (Lakthan Karn Mi Khun Sombat))*
  - Workcation: Employment contract or employment certificate with an overseas employer, or a professional portfolio for self-employed remote workers and freelancers
  - Soft-power activity: Letter of acceptance from the training institute, company, or hospital appointment letter
  - Dependent: Primary DTV holder's government identification, passport biodata, and DTV visa approval
  - _Note:_ The applicant selects exactly one of the three DTV tracks; the evidence package matches that track and is filed alongside the financial-threshold bank statements.
- **BOI endorsement evidence (LTR and Smart Visa)** *(หลักฐานการรับรองจาก BOI (Lakthan Karn Rap Rong Chak BOI))*
  - Required: Category-specific qualification proof — income, asset, employer-revenue, education credentials for the master's-degree income-reduction alternative, investment placement evidence (where the LTR category requires investment), and the marriage and birth certificates for dependents
  - Where to get: Board of Investment — Thailand Investment and Expat Services Center (LTR), or the Board of Investment Smart Visa Unit (Smart Visa)
  - Cost: Already issued
  - _Note:_ Smart Visa applicants must obtain the Letter of qualification endorsement from the Smart Visa Unit (BOI) before approaching the consulate; the consulate does not accept Smart Visa applications without it.
- **Health insurance certificate (LTR)** *(กรมธรรม์ประกันสุขภาพ (Krommathan Prakan Sukkhaphap))*
  - Accepted: Health insurance of at least USD 50,000 coverage, or evidence of Thai social-security enrolment, or a bank deposit statement showing USD 100,000 maintained for 12 or more months (USD 25,000 per dependent)
  - Cost: Varies by insurer
  - _Note:_ The medical-financial floor is identical across the four LTR primary categories; dependents are assessed separately at the lower USD 25,000 per-dependent threshold.

## Costs

- **Non-Immigrant B visa (single-entry, 90 days):** 80 USD — Washington D.C. consular district published fee. Other Royal Thai Embassy / Consulate locations may publish a modestly different USD-equivalent fee; cross-reference with the consulate handling the application.
- **Non-Immigrant B visa (multiple-entry, 1 year):** 200 USD — Washington D.C. consular district published fee; other Royal Thai Embassy or Consulate locations may publish a modestly different USD-equivalent figure. Multi-entry stamp authorises re-entry across the validity window; 90-day reporting (TM47) obligation still applies for stays exceeding 90 days.
- **Destination Thailand Visa (DTV, 5-year, multiple-entry):** 400 USD — Washington D.C. consular district published fee; other Royal Thai Embassy or Consulate locations may publish a modestly different USD-equivalent figure. Each entry permits up to 180 days of stay, extendable once. The DTV is issued only via e-Visa; no paper application channel is accepted.
- **Smart Visa (any sub-category, 1–4 year):** 400 USD — The fee covers the issuance for the validity duration granted by the BOI endorsement; it is not annual. The Letter of qualification endorsement from the SMART VISA Unit (BOI) must be uploaded with the consular package.
- **Long-Term Resident Visa (10-year) — overseas collection:** 1600 USD — Washington D.C. consular district published fee; other Royal Thai Embassy or Consulate locations may publish a modestly different USD-equivalent figure. Collected within 60 days of the BOI endorsement letter issuance; late collection requires re-application for endorsement.
- **Long-Term Resident Visa (10-year) — in-country collection:** 50000 THB — In-country option for applicants already in Thailand on another status. The endorsement letter remains valid for 60 days; the One Stop Service Center handles both the visa issuance and the LTR Digital Work Permit.
- **LTR Digital Work Permit (annual):** 3000 THB — Exempted from the standard 4:1 Thai-to-foreigner employment ratio that applies to ordinary work permits.
- **LTR application via the BOI direct system:** 0 THB — Direct online application via the BOI LTR portal carries no application fee — only the visa-issuance fee on collection (USD 1,600 abroad or ฿50,000 in-country).

## Steps

### 1. First step — Identify the route that matches the applicant's purpose and eligibility profile

- (Applicant) Identify the route that matches the proposed activity in Thailand — the วีซ่า Non-Immigrant B (Wiza Non-Immigrant B) for employment, business, or teaching with a Thai entity; the วีซ่า DTV (Destination Thailand Visa) for remote work for an overseas employer, Thai soft-power training, or as a dependent of a DTV holder; the วีซ่า LTR (Long-Term Resident Visa) for Highly-Skilled, Work-from-Thailand, Wealthy Global Citizen, or Wealthy Pensioner profiles; and the Smart Visa for specialist talent, investors, executives, or startup entrepreneurs in targeted industries
- (Applicant) Confirm the route-specific financial threshold — USD 1,000 or USD 2,000 per month for Non-Immigrant B; ฿500,000 (or USD 16,000) per month for DTV; the four LTR category thresholds and the USD 100,000 deposit floor (or insurance equivalents); the Board of Investment Smart Visa Unit schedule (published on engagement)
- (Applicant) For LTR Wealthy Pensioners on the USD 40,000 reduced-income track, confirm the USD 250,000 investment placement plan — Thai Government Bonds with 5+ years remaining maturity, a Thai company, or Thai property — before approaching the Board of Investment

> **Tip:** There is no automatic ladder progression between routes; each is a parallel pathway with its own eligibility profile and benefit set. An applicant chooses the route that matches the work, residence, or training purpose at hand.

> **If this fails:** Mismatched route — for example applying for the DTV for employment with a Thai company that should route to the Non-Immigrant B and Work Permit pathway — is the leading cause of refusal for first-time applicants. Confirm the route fits the actual purpose before assembling the package.

### 2. Non-Immigrant B — Thai employer secures the WP3 approval from the Ministry of Labour

- (Employer) Files for the WP3 (ใบ WP3 — Bai WP3) at the Department of Employment, Ministry of Labour, before the applicant approaches the Royal Thai Embassy
- (Employer) Provides the applicant with the WP3 letter, the invitation or employment letter naming the applicant and purpose, and the company's authorising signature
- (Applicant) Internship applicants substitute the WP3 with a letter from the Thai company confirming the internship period and position; teaching applicants additionally submit a criminal-clearance certificate from the FBI or state police issued within the prior three months

> **If this fails:** Filing the Non-Immigrant B at the consulate before the WP3 is in hand triggers consular rejection. The WP3 is the Ministry's pre-approval — the consulate uses it as evidence the employment is sanctioned.

### 3. Non-Immigrant B / DTV — Register on the Thailand e-Visa portal and submit the consular package

- (Applicant) Registers on the Thailand e-Visa portal (thaievisa.go.th) — the e-Visa portal is the exclusive consular filing channel; paper applications are not accepted
- (Applicant) Uploads the passport biodata page, recent photograph within six months, proof of current location, three months of bank statements at the route-specific threshold, and the route-specific evidence package (WP3 plus invitation or employment letter for Non-Immigrant B; track-specific evidence for DTV)
- (Applicant) Pays the consular fee — USD 80 (single-entry) or USD 200 (multiple-entry) for Non-Immigrant B; USD 400 for DTV
- (Royal Thai Embassy or Consulate) Issues the e-Visa approval after document review; some consular districts call applicants for interview before issuance

> **Tip:** Royal Thai Embassy fees may vary modestly by consular district due to exchange-rate updates; the cited USD figures reflect the Washington D.C. surface. Confirm the binding fee with the mission handling the application.

> **If this fails:** Incomplete submissions delay issuance — the embassy notes that missing evidence will delay the visa processing time. Confirm every document is uploaded in the required format before paying the fee.

### 4. Long-Term Resident Visa — Submit the BOI endorsement application and assemble category-specific evidence

- (Applicant) Registers and submits the online application on the Board of Investment LTR portal (ltr.boi.go.th) with the category-specific evidence package — income statements for the past two years (Highly-Skilled and Work-from-Thailand), asset statements (Wealthy Global Citizen), pension or passive-income statements (Wealthy Pensioner)
- (Applicant) Uploads the medical-financial-floor evidence — health insurance of USD 50,000, evidence of Thai social-security enrolment, or a USD 100,000 deposit maintained 12 or more months (USD 25,000 per dependent)
- (Applicant) Uploads the investment-placement evidence where the category requires it — USD 500,000 for Wealthy Global Citizen, or USD 250,000 for the Wealthy Pensioner reduced-income track
- (Board of Investment — Thailand Investment and Expat Services Center) Processes the qualifications endorsement in approximately 20 working days, followed by pre-approval in 1–3 working days

> **Tip:** BOI publishes the LTR fee schedule on the LTR portal directly: "50,000 Baht per person" — processing fee for 10-year visa collected in Thailand; work permit at 3,000 Baht annually. The overseas-collection rate (USD 1,600 via the Thailand e-Visa portal) is the alternative for applicants collecting at a Royal Thai Embassy abroad.

> **If this fails:** LTR deposits funded within the prior 12 months — even at the USD 100,000 level — do not satisfy the medical-financial floor. Maintain the deposit (or per-dependent USD 25,000) for 12 or more months before submitting the endorsement application, or substitute insurance or Thai social-security evidence.

### 5. Long-Term Resident Visa — Collect the visa abroad or in-country within 60 days of endorsement

- (Applicant) Collects the visa abroad at a Royal Thai Embassy or Consulate via the Thailand e-Visa portal — USD 1,600 — OR in Bangkok at the BOI One Stop Service Center — ฿50,000
- (Applicant) If working in Thailand, applies for the LTR Digital Work Permit at the One Stop Service Center — ฿3,000 per year, exempted from the 4:1 Thai-to-foreigner employment ratio that applies to ordinary work permits
- (Applicant) Confirms the dependent admission for spouse and up to four children under 20, each with the USD 25,000 per-dependent deposit (or insurance equivalent) maintained 12+ months

> **Tip:** The endorsement letter is valid for 60 days from issuance. Collection in the same 60-day window at a consulate abroad or the One Stop Service Center in-country is mandatory; expired endorsements require re-application.

### 6. Smart Visa — Obtain the Letter of qualification endorsement from the BOI Smart Visa Unit

- (Applicant) Engages the BOI Smart Visa Unit on eligibility for the chosen sub-category (Talents, Investors, Executives, Startup Entrepreneurs, or the spouse-and-children sub-category) at smart-visa.boi.go.th or via direct contact at head@boi.go.th / +66 2 553 8111
- (Board of Investment — Smart Visa Unit) Publishes the category-specific salary, investment, and industry thresholds to the applicant on engagement (these thresholds are not published verbatim on the public landing page)
- (Board of Investment — Smart Visa Unit) Issues the Letter of qualification endorsement after assessment of the applicant's eligibility against the targeted-industry criteria

> **Tip:** The five Smart Visa sub-categories (T, I, E, S, O) align with Thailand's targeted-industry strategy. Category-by-category thresholds are released to applicants only on engagement with the Smart Visa Unit; do not assume thresholds from third-party commentary.

### 7. Smart Visa — File the consular application at a Royal Thai Embassy with the endorsement letter

- (Applicant) Files the consular application at a Royal Thai Embassy or Consulate via the Thailand e-Visa portal, uploading the passport biodata page, recent photograph within six months, document indicating current location, and the Letter of qualification endorsement from the SMART VISA Unit (BOI) — in JPEG or PDF format
- (Applicant) Pays the consular fee — USD 400
- (Royal Thai Embassy or Consulate) Issues the visa with validity of 1–4 years depending on the sub-category and the endorsement decision

> **If this fails:** Filing the Smart Visa at the consulate without the prior BOI endorsement letter triggers refusal — the consulate does not accept Smart Visa applications without it.

### 8. Maintenance — In-country reporting, extensions, and visa-class changes at the Immigration Bureau

- (Applicant) Files the 90-day report (TM47) at the สำนักงานตรวจคนเข้าเมือง (Samnakngan Truat Khon Khao Mueang — Immigration Bureau) on each 90-day anniversary of continuous stay for Non-Immigrant B and DTV holders; LTR holders file a 1-year report instead, and Smart Visa holders are typically exempt under the Smart Visa benefit set
- (Applicant) Files visa-class changes and DTV 180-day extensions at the Office of Immigration Bureau on Soi Suan Plu, off South Sathorn Road, Bangkok
- (Applicant) Files for a re-entry permit when leaving and returning on a single-entry Non-Immigrant B — multi-entry Non-Immigrant B, DTV, and LTR confer re-entry by default within the visa validity window

> **Tip:** Overstay fines and re-entry bars escalate with the length of overstay under the Immigration Act B.E. 2522 (1979) — voluntary departure after 90 days of overstay triggers a one-year bar, with apprehension-based bars escalating to ten years. File the 90-day report and any extension before the deadline.

## FAQ

### Which long-stay route fits a remote worker employed by an overseas company?

The Destination Thailand Visa Workcation track is the route designed for digital nomads, remote workers, foreign talent, and freelancers whose employer is overseas (or who are self-employed remote professionals). It carries a five-year multiple-entry validity with 180 days per entry, extendable once. The financial threshold is ฿500,000 (or USD 16,000) per month across three preceding months, or a sponsor letter at the equivalent level. The Long-Term Resident Visa Work-from-Thailand Professional category is a longer-validity alternative for the same applicant profile when income and employer thresholds are met — minimum USD 80,000 annual income (or USD 40,000 with a master's degree or higher) and employment by a publicly listed company, a private company with at least three years' operation and USD 50 million revenue, or a subsidiary of either. Source: https://washingtondc.thaiembassy.org/en/page/destination-thailand-visa-dtv-2024 and https://ltr.boi.go.th/.

### Can a Destination Thailand Visa holder work for a Thai company?

No. The DTV Workcation track is for remote work where the employer is overseas, or for self-employed remote professionals. Employment by a Thai company requires the Non-Immigrant B plus Work Permit pathway, the LTR Work-from-Thailand Professional category (where the employer is overseas), or the Smart Visa (where endorsed by the Board of Investment in a targeted-industry sub-category). Source: https://washingtondc.thaiembassy.org/en/page/destination-thailand-visa-dtv-2024.

### Does the Long-Term Resident Visa require a separate work permit?

Yes — LTR holders work under the LTR Digital Work Permit, issued by the BOI One Stop Service Center for ฿3,000 per year. The Digital Work Permit is exempted from the 4:1 Thai-to-foreigner employment ratio that applies to standard work permits. Source: https://ltr.boi.go.th/.

### How many dependents can an LTR holder bring?

Up to four — legal spouse and children under 20. Each dependent must meet the medical-financial floor: insurance of USD 50,000, Thai social-security coverage, or a USD 25,000 deposit maintained for 12 or more months. Same-sex marriages are explicitly recognised for LTR dependent admission. Source: https://ltr.boi.go.th/.

### What is the LTR 17% personal income tax — does it apply to every LTR category?

The 17% personal income tax rate is a benefit granted to Highly-Skilled Professionals working in qualifying activities, and applies to Wealthy Global Citizens where applicable. It is not automatic for Wealthy Pensioners (whose income is typically passive or pension-sourced and treated under the overseas-income exemption) or for Work-from-Thailand Professionals (whose income is sourced from an overseas employer). The reduced rate flows from the LTR endorsement and is not granted to other LTR categories by default. Source: https://ltr.boi.go.th/.

### Are Smart Visa eligibility thresholds published publicly?

Category-by-category thresholds are not published on the BOI Smart Visa landing page or on the embassy consular surface. The Board of Investment Smart Visa Unit publishes the detailed criteria to applicants on engagement at smart-visa.boi.go.th, or via direct contact at head@boi.go.th or +66 2 553 8111. The applicant must obtain the Letter of qualification endorsement from the SMART VISA Unit (BOI) before the consulate accepts the visa application. Source: https://www.boi.go.th/en/smart_visa.

### Does a Non-Immigrant B multiple-entry visa exempt the holder from 90-day reporting?

No — Non-Immigrant B holders staying in Thailand continuously for more than 90 days file the 90-day report (TM47) at the Immigration Bureau regardless of single or multi-entry status. The multi-entry stamp covers re-entry only, not the reporting obligation. LTR holders are exempt — the 90-day report is extended to a 1-year report. Smart Visa holders are typically exempt under the Smart Visa benefit set. Source: https://washingtondc.thaiembassy.org/en/page/non-immigrant-visa-b.

### Can a visa-type change happen in-country?

Permitted in defined cases at the Immigration Bureau Suan Plu office. The change is not automatic — the applicant must meet the criteria of the receiving visa class at the time of change, and the relevant endorsement (BOI for LTR or Smart Visa) must already be in hand. LTR in-country collection at the BOI One Stop Service Center is the most direct in-country pathway for endorsed applicants. Source: https://ltr.boi.go.th/.

### What happens if the LTR endorsement letter expires?

The endorsement letter is valid for 60 days from issuance. If the visa is not collected within that window — at a Royal Thai Embassy or Consulate abroad, or at the BOI One Stop Service Center in Bangkok — the applicant must re-apply for endorsement. Source: https://ltr.boi.go.th/.

### Can a Smart Visa refusal be appealed?

Refusals are issued by the Board of Investment Smart Visa Unit; the published guidance does not specify a formal appeal channel. Applicants typically re-apply with strengthened evidence — revised income documentation, alternative investment placement, alternative employer evidence. The same pattern applies to LTR endorsement refusals. Source: https://ltr.boi.go.th/.

## Local tips

- Royal Thai Embassy fees may vary modestly by consular district due to exchange-rate updates; the cited USD figures reflect the Washington D.C. published surface.
- Revenue-stamp denominations and consular cashier hours vary by mission — confirm the binding fee and payment channel with the consulate handling the application.

It covers four primary qualifying categories: Highly-Skilled Professionals (minimum USD 80,000 annual income, or USD 40,000 with a master's degree or higher in science or technology, in a targeted industry); Work-from-Thailand Professionals (same income thresholds with employment by a publicly listed company, a private company with at least three years' operation and USD 50 million revenue, or a subsidiary of either); Wealthy Global Citizens (minimum USD 1 million in global assets plus USD 500,000 invested across Thai Government Bonds with at least five years' remaining maturity, direct company investment, or Thai property); and Wealthy Pensioners (age 50 or older with USD 80,000 annual passive income, or USD 40,000 with an additional USD 250,000 investment).

- [Royal Thai Embassy, Washington D.C. — Non-Immigrant B Visa consular page](https://washingtondc.thaiembassy.org/en/page/non-immigrant-visa-b) — accessed 2026-05-22 — _T1_ — The Non-Immigrant B Visa is issued for conducting business, academic or teaching employment, or employment and internship with a Thai company.

Extensions and visa-class changes are filed at the Office of Immigration Bureau on Soi Suan Plu, off South Sathorn Road, Bangkok.
- [Royal Thai Embassy, Washington D.C. — Smart Visa consular page](https://washingtondc.thaiembassy.org/en/page/smart-visa) — accessed 2026-05-22 — _T1_ — The Smart Visa is a one-to-four-year visa for specialist talent, investors, executives, and startup entrepreneurs in targeted industries, issued after Board of Investment endorsement. The consular fee is USD 400. After endorsement, the application package consists of the passport biodata page, a recent photograph within six months, a document indicating current location, and the Letter of qualification endorsement from SMART VISA Unit (BOI), uploaded in JPEG or PDF format. The consulate does not accept Smart Visa applications without the prior endorsement letter.
- [Board of Investment — Smart Visa landing page](https://www.boi.go.th/en/smart_visa) — accessed 2026-05-22 — _T1_ — Smart Visa comprises five categories — T (Talents), I (Investors), E (Executives), S (Startup Entrepreneurs), and O (Spouse and Children) — designed to enhance Thailand's S-Curve industries.

The root portal returned an empty body at audit; substantive consular content was sourced from the Royal Thai Embassy Washington D.C. surface as the operative consular publication for the routes in scope.
- [Immigration Bureau — primary issuing authority for in-country extensions and visa-class changes (portal at immigration.go.th currently unreachable; service points functional). Citation routed via BOI Smart Visa surface that names the Immigration Bureau channel; authority cited honestly without verbatim quote from the unreachable Bureau domain](https://www.boi.go.th/en/smart_visa) — accessed 2026-05-22 — _T1_ — The Immigration Bureau (สำนักงานตรวจคนเข้าเมือง — Samnakngan Truat Khon Khao Mueang) is the in-country authority for visa extensions, visa-class changes, re-entry permits, and 90-day reporting. The Bureau's central office is at Soi Suan Plu, off South Sathorn Road, Bangkok. The immigration.go.th portal returned a WAF block at audit and is cited at authority-name level only; the service points remain functional at the published address.
