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).

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 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.
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.
Assembling the bundle in the required order with an index speeds up assessment and reduces requests for more documents.
Many countries set a minimum remaining validity and number of blank pages. Verify before your appointment.
Periodic reporting, address notification and work conditions are ongoing duties that affect the next extension.
Accepted translator categories differ by country; confirm the required type before ordering.
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.
Analyse the refusal grounds and address them; resubmitting the same file usually produces the same result.
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.
