Into which language must a certificate of single status be translated, and who certifies the translation for the Board of Investment?
As a rule the Board of Investment accepts a translation into the official language of the receiving country, or English where the rules allow it. Who may certify differs by destination: a translator accredited in that country, a NAATI-certified translator for Australia, or a translation certified through the Department of Employment for Thai-issued papers. The translation of a certificate of single status must reproduce document numbers, seals and signatures, and mark illegible text as such rather than guessing. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

How many layers of authentication does a certificate of single status need before the Board of Investment accepts it?
The standard chain for Thai documents is: issuing office → certified translation → the Department of Employment → the embassy or consulate of the destination country, where still required. For a certificate of single status used with the Board of Investment, the number of layers depends on whether the destination is an Apostille state and what form it accepts. Thailand deposited its instrument of accession to the Apostille Convention on 30 June 2026 and the Convention enters into force for Thailand on 28 February 2027 (source: HCCH). During the transition, confirm with the receiving authority whether it already accepts an Apostille or still requires embassy legalisation. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

Why would the Board of Investment reject a certificate of single status, and how do you fix it?
Recurring causes: a name spelled differently from the passport, an original older than the window the Board of Investment allows, an uncertified photocopy, a translation that drops a seal or document number, and an authentication chain done out of order. The fix is always upstream — obtain a fresh a certificate of single status or have the issuing office correct the data, then repeat the chain. Never amend by hand: the Department of Employment will not certify a document altered outside the official process. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

Can a certificate of single status be handled for the Board of Investment while I am overseas, without returning to Thailand?
In most cases yes: sign a power of attorney before a Thai embassy or consulate officer where you live, or before a local notary followed by the required onward authentication. Then courier the original a certificate of single status and the power of attorney to us; we complete certification with the Department of Employment and send the file back to your address. The exception is any step where the Board of Investment requires the holder to appear in person, which we check case by case. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

My name on a certificate of single status differs from my passport — will the Board of Investment still accept it?
Align them before filing, because the Board of Investment treats the passport as the primary identity reference. Options: (1) ask the issuing office to correct a certificate of single status if it is a recording error; (2) obtain a same-person certificate and have it certified through the Department of Employment; or (3) use the passport spelling in the translation with a transliteration note. Which route is accepted varies by destination, so confirm before starting. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

Does the Board of Investment accept a scan or copy of a certificate of single status, or only the original?
Certification must always be based on the original a certificate of single status or a copy certified by the issuing office. Scans are fine for an initial assessment and for drafting the translation. For the actual filing, some the Board of Investment channels let you upload first and inspect originals at the appointment. The safe approach is to keep the original ready and to retain one spare certified set. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

I need a certificate of single status urgently this week for the Board of Investment — is that possible?
Sometimes, depending on whether the original a certificate of single status is already in hand and whether the Department of Employment is running an expedited channel that week. What speeds things up most: send photos of every page for a pre-check, tell us your exact the Board of Investment appointment date, and prepare the power of attorney in advance. If your deadline is not achievable we say so plainly rather than risk your appointment. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

I need several certified sets of a certificate of single status for the Board of Investment — how should I plan it?
Tell us the number of sets at the start, because adding sets later means running the whole chain again. We generally suggest one spare beyond what you need, since the Board of Investment usually keeps the filed set. If the documents will be used in more than one country, prepare separate sets per destination — the certification format at the Department of Employment and the translation requirements can differ. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

What drives the cost of handling a certificate of single status for the Board of Investment?
The main drivers are the page count and text density of a certificate of single status, the language pair, how many authentication layers the Board of Investment requires, the number of sets, urgency, and the official fees set by the Department of Employment. We do not publish prices on the site because cases genuinely differ and a generic figure would lead to wrong planning.

How do I receive the certified a certificate of single status — can it be shipped upcountry or abroad?
You can collect at the office, meet at an agreed pick-up point, or have the file shipped with tracking, domestically or internationally. For overseas shipping use a tracked service and give a recipient name matching your ID, as some countries scrutinise inbound official documents. We always photograph the finished a certificate of single status set for your approval before dispatch, so you can verify it before it reaches the Board of Investment. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

What is the step-by-step process for a certificate of single status (Thai work permit) to be used with the Revenue Department?
There are four stages: (1) verify that the original a certificate of single status was issued by the competent authority and that names, document number and dates are legible; (2) prepare the translation or certification in the format the Revenue Department accepts; (3) submit for certification by the Department of Employment; (4) deliver and re-check everything before the actual filing. The most common delay is a name spelling that differs from the passport, so send a passport copy with the first submission. For the exact fee and turnaround for your case, please contact our staff by phone, LINE or email.

Which supporting documents are needed for a certificate of single status when filing with the Revenue Department?
The baseline set is: the original a certificate of single status (or a copy certified by the issuing office), a copy of the holder's passport or ID card, and a power of attorney if someone else acts on your behalf. If the Revenue Department prescribes its own form, the entries must match the source document character for character. Submit every page, including pages that only carry a seal, because the Department of Employment certifies exactly the bundle presented.

How long does a certificate of single status take before it can be filed with the Revenue Department?
Three variables drive the timeline: the readiness of the original a certificate of single status, the certification queue at the Department of Employment, and the intake schedule of the Revenue Department. When the original is complete and no re-issue is required, drafting and certification usually run in working days, while government queues shift with filing season. We give you a realistic estimate once we have seen your documents, and we advise against booking flights or appointments before the papers are in hand.

How long does a certified a certificate of single status stay valid for the Revenue Department?
The certification itself does not expire, but the Revenue Department usually requires civil-status documents to have been issued within a set window before filing (commonly 3 or 6 months). What counts is the issue date of the original a certificate of single status, not the certification date. If your filing date is still open, obtain the original as close to filing as possible and certify afterwards to avoid repeating the work.

Work permits, BOI/IEAT privileges, Treaty of Amity and APEC card — practical answers
First-party answers on Thai work authorisation: the standard Department of Employment route, BOI and IEAT channels for skilled experts, US company rights under the Treaty of Amity, and the APEC Business Travel Card for Thai nationals — including which supporting documents must be translated and legalised first. (19+ search topics covered)
What is the IEAT route?
Operators inside industrial estates governed by the Industrial Estate Authority of Thailand may be permitted to bring in skilled workers, experts and their families under the IEAT Act. It is a separate legal basis from BOI promotion, but the work permit and stay formalities still have to be completed with the responsible agencies.
Is a work permit the same as a visa in Thailand?
No. A visa such as Non-Immigrant B is issued by a Thai embassy or consulate, extensions of stay are approved by the Immigration Bureau, while the work permit itself is issued by the Department of Employment under the Emergency Decree on Managing the Work of Aliens B.E. 2560 (2017). Holding a valid visa does not by itself authorise employment, and working before authorisation carries legal penalties, so both tracks must be planned together.
What happens to the permit if I change employer or job title?
Authorisation is granted by reference to the employer, workplace and described duties, so a change in any of them normally requires a filing rather than a private arrangement. Continuing to work under the old permit after the change is treated as unauthorised work. Plan the change with the new employer before resigning, because the gap between employments also affects the underlying permission to stay.
Can dependants of a work-permit holder work?
Permission to stay as a dependant and permission to work are separate matters. Dependants admitted on the basis of the principal's status do not gain an automatic right to work; they need an employer and their own work permit application under the normal criteria. Children entering school require a separate process, including certified translations of academic records.
Which comes first, the visa or the work permit?
In the usual sequence, the foreign national first holds a non-immigrant visa consistent with the intended employment, then applies for a work permit under the law on managing the employment of foreign workers, administered by the Department of Employment. Continued stay afterwards is decided separately by the Immigration Bureau. The three systems are distinct but interlocking, and a gap in one blocks the next.
Does Treaty of Amity status remove the work permit requirement?
No. The treaty concerns the company's right to do business, not an individual's right to work. US executives and staff still need an appropriate visa category and a work permit under the same rules as other foreign nationals.
How are foreign degrees and experience letters handled?
They usually must be translated into Thai or English as required and legalised through the diplomatic chain: certified in the issuing country (apostille where that country is a Convention party), then endorsed by the Royal Thai Embassy, or endorsed by that country's embassy in Thailand and then legalised by the Legalization Division of the Department of Consular Affairs before submission.
What must be done when changing employer or job title?
A work permit is tied to the conditions recorded in it, including employer, position and place of work, so material changes must be notified or amended under the applicable law before working under the new conditions. Changing employer also usually affects employment-based permission to stay, so the two processes should be planned together. Typical documents are a letter from the new employer, corporate registration papers and the new employment contract; verify the current procedure with the Department of Employment.

Thai work permit — company-side and employee-side documents
Work permits are issued by the Department of Employment and are tied to the employer, position and workplace. Changing job, role or location requires a new filing.
Documents to prepare
- • Company side: current affidavit, shareholder list, financial statements, social security filings
- • Employee side: passport, the correct visa category, and the required medical certificate
- • Degrees and experience letters, legalised at source and translated for Thai use
- • Employment contract and job description
- • Workplace map and photographs where requested
- • Power of attorney for the company's filing agent
Step-by-step process
- 1. Check company and role eligibility — Registered capital, Thai-to-foreign staff ratio and reserved occupations are verified first.
- 2. Prepare foreign documents — Qualifications and experience letters must be legalised abroad and translated before filing.
- 3. File the application — Through the Department of Employment, or a dedicated channel such as the BOI One Stop Service.
- 4. Collect and comply — Work only within the stated role and location, and renew before expiry.
Pitfalls and rejection causes
- • Working outside the stated role or location breaches the permit conditions.
- • A permit belongs to the employer — it cannot follow you to a new company.
- • Visa and permit expire on different dates; track both.
- • Company documents older than the accepted window must be reissued.
Tips from our team
- • Set reminders at least 45 days before either expiry date.
- • Maintain a standing company document pack to speed up future filings.
- • BOI-promoted companies should use the dedicated channel to cut steps.

Route Comparison
Comparing Thai work permit routes
Different employer types use different channels, and each channel pairs with a different visa category.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Standard filing with the Department of Employment | The employer is an ordinary Thai company without BOI promotion | Department of Employment, Ministry of Labour | Variable, driven by how complete the employer's file is | Thai-to-foreign staff ratios and registered capital not meeting thresholds is the common refusal ground |
| BOI-promoted company channel | The employer holds a promotion certificate and the position is on the approved list | BOI together with the Immigration Bureau and Department of Employment | Generally faster than the standard route, still variable | A position that differs from the approved list requires an amendment first |
| Conditional or short-term work authorisation | Short assignments or job types covered by specific published rules | Department of Employment under the notification in force | Shorter than a full application | Working beyond the authorised scope is an offence even when a permit exists |
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.

We do not just process documents — we advise you through the whole 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.
Route assessment
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Pre-submission review
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
Timeline planning
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
Rejection recovery
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.

Practical Q&A
Practical questions · Near me / DIY / Required documents
Where is a Thai work permit filed, and must the employee attend?
Applications are filed with the Bangkok area employment office or the provincial employment office covering the workplace, under the Department of Employment, Ministry of Labour. Some categories can be filed through the e-Workpermit system. An employer or authorised representative may file, but the employee may still be asked to appear. We can assemble and pre-check the document set; contact our team by phone, LINE or email.
How must foreign supporting documents be translated and certified?
Foreign degrees or experience letters are first certified in the issuing country and by the relevant embassy, then translated into Thai or English as required by the receiving office, and finally legalised by the Legalization Division of the Department of Consular Affairs. Doing these steps out of order is the most common cause of rejection.
Can I handle the application myself?
Yes, the Department of Employment procedure is open to applicants and employers. Delays usually come from outdated forms, company documents older than the office accepts, and translations that do not match the required format. Check the current checklist of the office you will file with before you start.
Practical advice & cautions
Visa and immigration matters: advice and cautions
Before you start
Keep every receipt and acknowledgement
Photograph all filing receipts and stamps; they are key evidence in any later verification.
Plan around expiry dates
Extensions, reporting and re-entry permits should be handled well ahead of the deadline; queues and public holidays can make last-minute filing impossible.
Order documents to the authority's checklist
Assembling the bundle in the required order with an index speeds up assessment and reduces requests for more documents.
Check passport validity and blank pages
Many countries set a minimum remaining validity and number of blank pages. Verify before your appointment.
Common reasons documents get rejected
Ignoring post-approval obligations
Periodic reporting, address notification and work conditions are ongoing duties that affect the next extension.
Form data contradicting the attachments
Dates, addresses or travel history that conflict with supporting documents are a frequent refusal ground and may be read as misrepresentation.
Refiling immediately without fixing the cause
Analyse the refusal grounds and address them; resubmitting the same file usually produces the same result.
Believing guaranteed-approval claims
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.
