Service Knowledge Base

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 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.

Must authorisation be obtained before starting work?

Yes. A foreign national must hold the permit before performing work, and may only do the role, for the employer and at the locations stated in the permit. Trial periods and side assignments outside that scope are not covered. Changes of employer, position or workplace require notification or amendment through the Department of Employment.

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.

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.

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.

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.

Which authority decides a work permit, and what does it not cover?

The Department of Employment under the Ministry of Labour administers work authorisation for foreign nationals; the Immigration Bureau separately administers the right to stay. A work permit does not extend your permission to stay, and a valid visa does not authorise work. Both must be kept aligned, because expiry of one commonly triggers problems with the other at the next renewal.

How are foreign degrees and experience letters used for a Thai work permit?

They are normally authenticated by the competent authority in the issuing country and by the Royal Thai Embassy there, or by apostille once the Convention enters into force for Thailand on 28 February 2027 where accepted, then translated into Thai and legalised by the Department of Consular Affairs. Experience letters should state the position, exact dates, duties and the issuer's contact details, because verification enquiries do occur. Confirm the document list with the Department of Employment or the receiving office before preparing the file.

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.

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.

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 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.

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.

Practical Q&A

Practical questions · Near me / DIY / Required documents

Is there a service point near me?

Our main offices are Lat Phrao 95 (Bangkok), Khon Kaen and Udon Thani. We serve the whole country through scans and document courier, and can meet at city rail stations or malls. Ask our team by phone, LINE or email for the most convenient option.

Can I handle this myself?

Many steps can be done personally under the relevant authority's rules. What usually costs time is the wrong sequence, a translation format that does not match the requirement, or a source document version the recipient will not accept. Check the destination checklist before starting and ask us if anything is unclear.

Which documents should I prepare?

Generally the original document from the competent authority, the owner's ID or passport, a translation in the format the destination requires, and a power of attorney if someone acts for you. Details vary by service type — ask our team for a case-specific checklist.
Practical advice & cautions

Legalization & apostille: practical advice and cautions

Before you start

  • Separate public documents from private ones

    Public records such as house registration, birth and marriage certificates enter the certification chain directly. Private documents such as powers of attorney, affidavits and contracts must first be attested by a Notarial Services Attorney.

  • Allow for each step's queue

    Total turnaround depends on the current workload of the consular office and of the destination embassy. Plan ahead rather than against a tight travel date; we can give a case-specific range by phone, LINE or email.

  • Keep a scanned backup at every stage

    Photograph or scan every page before submission and again after each stamp, so you have a reference if a document is lost in transit.

  • Prepare translations in the format the certifying office actually uses

    The Department of Consular Affairs certifies translations presented in its expected format. Self-formatted translations are frequently sent back for correction, costing a full queue cycle.

Common reasons documents get rejected

  • Certifying a copy that no longer matches the register

    If a registry entry changes after the copy was issued, for example a name change or address move, the certified copy will contradict the database. Re-issue before starting.

  • Assuming a Thai lawyer is a common-law notary public

    Thailand has no common-law notary public. The equivalent role is a Notarial Services Attorney registered with the Lawyers Council of Thailand. Describing it incorrectly can cause the receiving party to reject the document.

  • Opening a bound and sealed bundle

    Bundles sealed across the binding must never be separated. Removing the staple voids the certification and the whole set has to be redone.

  • Signature mismatch

    Signature attestation is compared against the signature on the ID card or passport. A different signature style will be refused at the counter.

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.
