Need your documents reviewed or your case assessed? Ask our team by phone, LINE, or email. We reply within two hours during business hours (Mon–Sat 9:00–18:00 ICT).
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.
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.
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.
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.
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.

The Department of Home Affairs applies different rules: translations made in Australia must be done by a NAATI-certified translator, while translations made outside Australia must show the translator's full name, address, telephone number and qualifications on the translation.
NAATI is Australia's credentialing system for translators and interpreters and is mainly relevant to Australian authorities — visas, qualification assessment and professional registration. Other countries use their own systems, so verify the requirement before ordering.
A NAATI translation is not legalisation. Use in Thailand or a third country may still require translation certification or authentication under that authority's rules. Ask our team by phone, LINE or email to sequence the steps first.
Scan at 300 dpi or better so seals, signatures, document numbers and reverse-side text are legible. Anything unreadable must be marked as illegible in the translation, which commonly triggers a request for further documents.
NAATI certification is subject to recertification cycles. If the stamp's expiry date falls before your lodgement date, the authority may refuse the translation — always check the date on the stamp.
Seals, signatures, footnotes and reverse-side text are part of the document. Translations that omit them are commonly rejected.
If the name on the translation does not match the passport or other documents in the same application, the authority will ask for linking evidence such as a change-of-name certificate.
If the original has been reissued or amended, the earlier translation no longer matches what you lodge. Always translate the exact version you will submit.
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.
One document set often moves through several stages — translation, notarial certification, legalization and finally a visa filing. The links below follow that real sequence.
Authority requirements change. Verify with the receiving authority before filing, or ask our team by phone, LINE or email.
For Australian government submissions, the translation must be produced by a translator holding current NAATI certification in the relevant direction. Verify the practitioner's NAATI number and certification status, confirm the direction covers Thai to English, and check that the stamp and translator statement appear on every page you submit.
| Option | Best for | What to know |
|---|---|---|
| Direct NAATI practitioner | Small files with a single document type | Capacity and turnaround depend on one individual. |
| Agency working with NAATI practitioners | Multi-document visa and skills-assessment files | Ask which practitioner will sign, not just that the agency uses NAATI translators. |
| Provider covering translation and downstream legalization | Files also needing Thai consular steps | Confirm both scopes are quoted and both timelines are stated. |
