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 rights does the Treaty of Amity give US companies?

The 1966 Treaty of Amity and Economic Relations lets US nationals and majority US-owned companies operate in Thailand on largely the same footing as Thai nationals, exempt from many restrictions of the Foreign Business Act B.E. 2542, with some sectors still excluded such as land and certain resource activities. Use of the treaty requires nationality certification through the US Embassy and registration with the Department of Business Development.

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.

What must an employer prepare for a first foreign hire?

Typically current company records — registration certificate, shareholder list, financial statements and tax filings — together with social security registration for employees and an employment contract whose job title and scope match the permit sought. Ratio requirements for Thai employees or minimum registered capital may apply under the rules in force, so the corporate structure should be reviewed before filing begins.

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.

Why are Thai work permit applications commonly returned?

The usual reason is that the job title and duties in the application do not match the employer's supporting documents, such as the company affidavit, financial statements and employment contract. Other frequent causes are qualifications claimed without properly certified translations, and applying under a business activity that is not among the objectives registered with the Department of Business Development. Map every document to the same set of facts before filing and confirm the current requirements with the Department of Employment office responsible for the workplace.

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.

Who can obtain an APEC Business Travel Card?

The card facilitates business travel among participating APEC economies and is issued to Thai business people by the Department of Consular Affairs, subject to endorsement by the designated authorities. Pre-clearance for each economy is decided by that economy, and the card does not grant the right to work abroad.

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.

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. 1. Check company and role eligibility — Registered capital, Thai-to-foreign staff ratio and reserved occupations are verified first.
  2. 2. Prepare foreign documents — Qualifications and experience letters must be legalised abroad and translated before filing.
  3. 3. File the application — Through the Department of Employment, or a dedicated channel such as the BOI One Stop Service.
  4. 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.

RouteWhen to useCertifying authorityApprox. durationRejection risk
Standard filing with the Department of EmploymentThe employer is an ordinary Thai company without BOI promotionDepartment of Employment, Ministry of LabourVariable, driven by how complete the employer's file isThai-to-foreign staff ratios and registered capital not meeting thresholds is the common refusal ground
BOI-promoted company channelThe employer holds a promotion certificate and the position is on the approved listBOI together with the Immigration Bureau and Department of EmploymentGenerally faster than the standard route, still variableA position that differs from the approved list requires an amendment first
Conditional or short-term work authorisationShort assignments or job types covered by specific published rulesDepartment of Employment under the notification in forceShorter than a full applicationWorking 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.

Advisory Service

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 since 2015. 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?

Ask the recipient which originals, copies, translation language and authentication are required. Nationality or Apostille membership of the issuing country alone does not establish acceptance by a Thai recipient.

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
  • 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.

  • Make funds explainable

    Large deposits made shortly before filing attract questions. Support them with evidence of income and use statements bearing the bank's original seal.

  • Keep every receipt and acknowledgement

    Photograph all filing receipts and stamps; they are key evidence in any later verification.

  • Read the official conditions first

    Visa conditions change. Check the deciding authority's latest announcement, then use our service to prepare documents and translations that match those conditions.

Common reasons documents get rejected
  • Expired supporting documents

    Civil registry extracts, medical certificates and police clearances have limited validity; old copies make the bundle incomplete.

  • Translations the destination does not accept

    Accepted translator categories differ by country; confirm the required type before ordering.

  • 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.

  • 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.

Choosing a document translation provider in Thailand

Pick a translation provider by the destination, not by turnaround alone. If the file goes to the Thai Department of Consular Affairs or an embassy, the translator must know the format that office accepts, not just the meaning. Verify three things: the certifier is named and identifiable, the destination accepts that certification format, and names, dates and document numbers match the passport character for character.

How to evaluate a provider

  • The certifier is named and identifiable — Consular offices and embassies check who certified the translation, not only the wording.
  • Knows the format the destination accepts — Each embassy differs: attached source copy, letterhead, or prior consular legalization.
  • Character-level verification — Mismatched name spelling and dates against the passport is the most common rejection cause.
  • Owns corrections after rejection — Submissions run on appointment dates; slow corrections cost the applicant the slot.
  • Documented custody of originals — Some civil registry documents are hard to reissue, so intake and return must be traceable.

Questions to ask before you commit

  1. If the receiving authority rejects or asks for changes, do you correct it, and under what terms?
  2. How can I track status, and who physically holds the original documents?
  3. Who will certify this translation, and will the certifier be named on the document?
  4. Does my destination require consular or embassy legalization afterwards?
  5. How many working days does it actually take, counted from a complete file?

Your options, and who each suits

Translation agency with certificationVisa, study and civil registry filingsConfirm the agency also handles the legalization step if the destination requires it.
End-to-end provider (translate + legalize)Files with a fixed appointment deadlineAsk which steps are in-house and which are subcontracted.

FAQ on choosing a provider

Which translation service is recommended for embassy submissions?
Choose one that names the certifier on the translation, knows the exact format your embassy accepts, and verifies names and dates against the passport before certifying. Ask whether they also handle consular legalization so the file does not stall between two vendors.
Does a cheaper translation get rejected more often?
Rejection correlates with format and verification, not price. A translation is rejected when the certifier cannot be identified, the layout does not match the receiving office's requirement, or a name or date differs from the passport.
