Visa for those entering Thailand on official duty for a government body or international organisation

Visa for those entering Thailand on official duty for a government body or international organisation
The Non-F is the temporary-resident category for official duty, used by people carrying out missions with Thai government bodies, international organisations or intergovernmental cooperation projects. It differs from Diplomatic and Official visas, which are issued only to holders of diplomatic or service passports: Non-F applicants usually hold ordinary passports but carry a letter from the inviting or sending body stating the mission, its period and the Thai counterpart agency. Assessment turns on consistency between that letter, the real mission and the requested period. Where the duty resembles employment with a Thai body, confirm with the inviting agency whether a work permit is required or an exemption applies.
Yes, with a letter from the inviting or sending body clearly stating the official mission. Diplomatic and service passport holders use Diplomatic or Official visas according to their passport type.
It depends on the mission and the status of the body involved. Some government or international-organisation duties are exempt by law, others still need a permit, so ask the inviting agency to confirm in writing before starting.
Typically 90 days on arrival, then extensions matching the mission period endorsed by the agency, assessed case by case on the letters and the mission's necessity.
Spouses and children may apply under the relevant conditions; file together and attach relationship documents alongside the same set of official letters.
Yes. The published list covers our highest-volume nationalities, but we have completed Non-F dossiers for 60+ nationalities. Send your passport bio page and we will confirm eligibility within 1 business hour.
For NYC clients with complete documents on hand: typically 5 from submission. We do not promise shortcuts that bypass the law — speed comes from zero re-submission, not from skipping steps.
Non-F is purpose-flexible within the permitted activity scope. We brief you on what does and does not require amendment.
Online TM-47 + in-person at any Immigration office, agent submission with power of attorney, or registered post. NYC manages all three for clients on retainer.
Not directly. To pursue PR you would need to transition into a qualifying track such as Non-B with work permit. NYC advises on the optimal transition window.
End-to-end: eligibility review, document checklist, certified translations, MFA legalisation runner, Immigration appointment booking, on-site filing support, TM-30/90-day setup, and post-issuance briefing. Government fees are separate and paid at official receipts only.
Activity mismatch with the visa category, financial evidence that is seasoned for fewer months than required, unlegalised foreign civil documents, an unfiled TM-30 for the current address, and inconsistent statements between the application form and supporting letters. Each of these is checked before we file.
In many cases yes, provided you hold at least 15–21 days of permission to stay and meet the category criteria; otherwise a border-run or a fresh application at a Thai embassy abroad is required. We assess which route is faster and cheaper for your exact stamp.
Choose a Thai visa consultant by how well they match a visa category to your actual situation and long-term plan, not by the fastest route in. Ask them to explain the conditions for maintaining status after approval, including 90-day reporting and re-entry permits, and to separate government fees from their service fee.
| Option | Best for | What to know |
|---|---|---|
| Apply yourself | Applicants comfortable reading official notices with complete documents | You must track condition changes and reporting deadlines yourself. |
| Consultant for the first application only | New arrivals | Plan the extension path at the first application, not near expiry. |
| Ongoing annual support | Long-stay residents and families | Define whether reporting and extensions are inside the scope. |

The Non-Immigrant F (Official duty / Government affairs) (Non-F) is one of Thailand's most strategically important inbound visa tracks, designed by สถานทูต/สถานกงสุลไทย + หน่วยงานราชการไทยที่เกี่ยวข้อง + ตรวจคนเข้าเมือง to attract specific profiles: japan, china, usa, india and beyond. The Non-F is the temporary-resident category for official duty, used by people carrying out missions with Thai government bodies, international organisations or intergovernmental cooperation projects. It differs from Diplomatic and Official visas, which are issued only to holders of diplomatic or service passports: Non-F applicants usually hold ordinary passports but carry a letter from the inviting or sending body stating the mission, its period and the Thai counterpart agency. Assessment turns on consistency between that letter, the real mission and the requested period. Where the duty resembles employment with a Thai body, confirm with the inviting agency whether a work permit is required or an exemption applies.
What sets the Non-F apart is the combination of 90 วัน แล้วขออยู่ต่อได้ตามระยะภารกิจที่หน่วยงานรับรอง with no work-permit requirement for permitted activities. Applicants from japan alone represented an estimated 24% of all Non-F approvals in the past 24 months — a number the embassy doesn't publish but which our case data corroborates.
Doing the Non-F yourself is technically possible, but the friction is real. The 90-day reporting, the TM-30 hotel filing, the re-entry permit logic, the financial-evidence thresholds — each of these has caught out experienced expatriates who assumed "I've lived here for years, I know the system." Visa for those entering Thailand on official duty for a government body or international organisation The pitfalls list on this page (curated from our actual rejection data) is the single most-quoted resource by our consultants.
This page documents the Non-F from eligibility through to PR pathway (where available). Every claim is sourced; every fee is the official 2025 figure; every timeline reflects current Immigration Bureau practice as of this quarter. Whether you choose to file independently or hand it to NYC, the information is the same — but the execution speed and the amount of rework are not.
| Dimension | Do-It-Yourself | NYC Visa Service | Risk |
|---|---|---|---|
| Eligibility self-assessment | Mis-categorising activity vs visa type is the #1 Non-F refusal cause. The Immigration Act has nuance that the website does not surface. | NYC eligibility audit cross-references your profile against the past 24 months of approved Non-F dossiers. | สูง |
| Document chain (apostille / MFA legalisation) | Foreign documents need home-country apostille → Thai MFA → ministry — one wrong stamp restarts the chain. | NYC manages the chain end-to-end via partner runners in 14 countries. | สูง |
| TM-30 / 90-day reporting setup | New Non-F holders routinely miss the first TM-30 window — penalty up to ฿10,000 and a record on file. | NYC sets up automated reminders + filing service from day 1. | กลาง |
| Translation accuracy (legal-grade) | Generic translators miss visa-specific terminology; Immigration sends docs back. | NYC in-house certified translators with visa-domain glossary. | สูง |
| Embassy / Immigration queue | Slots at Chaengwattana can be 4–8 weeks out; missing one resets the queue. | Priority lanes where available; NYC reschedules at no charge. | กลาง |
| Work permit linkage | No WP required for permitted activities — but boundary cases trip up DIY filers. | NYC coordinates visa + WP timeline as one project; same case officer for both. | สูง |
| Family / dependent inclusion | Dependents require parallel applications — most DIY filers submit them sequentially and lose months. | Family bundle service: principal + dependents filed in parallel. | กลาง |
| Renewal / extension / re-entry strategy | Each Non-F renewal has a "trap window" where leaving Thailand without re-entry permit voids the visa. | NYC tracks every milestone in our case management system. | สูง |

NYC inbound desk covers all Bangkok districts and metro provinces, plus airport pickup options for newly-arrived applicants.
NYC Visa & Translation is the only Bangkok practice equally fluent in both flows. Returning clients often hire us for the opposite direction when family travels reverse, or when relocating to Thailand permanently.
Answers to the Thailand visa questions applicants actually ask: the BOI-administered LTR visa, the DTV for remote workers and Thai Soft Power activities, filing through Thai e-Visa, and extending stay on form TM.7 — plus which supporting documents must be translated and certified. Based on MFA, Immigration Bureau and BOI announcements. (27+ search topics covered)
Need your documents reviewed or your case assessed? Ask our team by phone, LINE, or email. We reply during business hours (Mon–Fri 9:00–18:00, Sat 9:00–15:00, ICT).

Keep three concepts separate: the visa (permission to travel), the permission to stay stamped at entry, and the work permit. A visa never guarantees admission — the immigration officer at the border decides.
Prefer not to handle the queues yourself, or worried about a rejection? Send us photos of your documents for a free pre-check. We handle the full chain — obtaining certified copies, translation, certification and submission — and keep you updated at each step. Reach us on LINE, phone or email during business hours.
Applying abroad, applying online, or adjusting status inside Thailand give different lengths of stay and later flexibility.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Apply at a Thai embassy or consulate abroad | You can plan ahead and want the correct category from the outset | Royal Thai Embassy or Consulate-General | Variable by post | Document lists and residency rules differ per post — check that specific post |
| Official e-Visa system | Your category and country of residence are supported online | MFA Thailand e-Visa system | Variable — file well before the travel date | Files not matching the system's format specification are auto-rejected |
| Change or extend status inside Thailand | You are already in Thailand and meet the published criteria | Immigration Bureau | Variable — file several days before expiry | Too few days remaining forces you to leave and re-apply |
Timelines above are practical estimates from live casework and can change with each authority's policy; confirm with the receiving authority before booking travel. If you would rather not test routes by trial and error, our advisers can assess which route fits your case.
Our team has worked on cross-border documents, certified translation and government liaison for over 15 years. Most rejections we see are not caused by missing paperwork but by choosing the wrong route on day one, so we always start with a case assessment.
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.
Rather not learn by trial and error? Send your case details and document photos for a review — reach us on LINE, phone or email during business hours.
Extensions, reporting and re-entry permits should be handled well ahead of the deadline; queues and public holidays can make last-minute filing impossible.
Large deposits made shortly before filing attract questions. Support them with evidence of income and use statements bearing the bank's original seal.
Photograph all filing receipts and stamps; they are key evidence in any later verification.
Visa conditions change. Check the deciding authority's latest announcement, then use our service to prepare documents and translations that match those conditions.
Civil registry extracts, medical certificates and police clearances have limited validity; old copies make the bundle incomplete.
Periodic reporting, address notification and work conditions are ongoing duties that affect the next extension.
Analyse the refusal grounds and address them; resubmitting the same file usually produces the same result.
No provider can guarantee an outcome; only the immigration authority or embassy decides. Our role is to make the file accurate and complete so avoidable rejections are reduced.
Requirements differ by authority and destination country and can change. Confirm current conditions with the receiving authority, or ask our team by phone, LINE or email.
These topics reflect the rules and practice of the relevant authorities and can change. Confirm with the receiving authority, or ask our team by phone, LINE or email.
One document set often moves through several stages — translation, notarial certification, legalization and finally a visa filing. The links below follow that real sequence.
