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.

Liability depends on tax residence and any applicable double-tax agreement; evaluate before moving funds or receiving cross-border income.
Mixed accounts complicate financial statements and tax explanations, and cause problems when bank evidence supports a visa or work permit.
Shareholding, objectives and required licences should be settled before filing; later changes require amendment filings and extra time.
Cross-border contracts should state which language version prevails and how disputes are resolved.
Changes of director, address or capital must be filed within the statutory period; omissions create mismatches that block other applications.
Using nominees to bypass foreign business restrictions carries serious legal risk. Structure the company lawfully from the outset.
Late filing triggers statutory surcharges and penalties and can affect renewal of foreign executives' work permits.
Certificates submitted should be freshly issued and consistent with the current register, or the receiving authority will refuse them.
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.
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.
| Option | Best for | What to know |
|---|---|---|
| Freelance translator | Informal use where no authority certification is required | Many embassies will not accept an uncertified translation. |
| Translation agency with certification | Visa, study and civil registry filings | Confirm the agency also handles the legalization step if the destination requires it. |
| End-to-end provider (translate + legalize) | Files with a fixed appointment deadline | Ask which steps are in-house and which are subcontracted. |
Choosing the right US–Thai Treaty of Amity Certification provider directly impacts the success and turnaround of your case. NYC Visa & Translation has worked with Department of Business Development + US Embassy Bangkok (US Commercial Service) since 2010, handling a broad real-world caseload across government documents, certified translations, and documents intended for use abroad. Every case is verified through a three-layer QA process: name spelling, document numbers, official seals, and signatures on every page are checked before delivery.
Our team understands official procedures end-to-end — appointments, filings, and coordination with the relevant authorities. You do not have to travel back and forth or risk rejection. Our US–Thai Treaty of Amity Certification service supports Express handling that completes in half the standard turnaround.
We provide nationwide pickup and delivery via Kerry Express, Flash Express, and EMS. Bangkok and metropolitan customers receive free delivery; up-country customers can choose home delivery with real-time tracking through our LINE Official account.
Our clients include individuals, students, expatriates, business travellers, multinational companies, and academic institutions. We handle every document type — house registration, ID card, passport, marriage certificate, birth certificate, diploma, transcript, employment certificate, power of attorney, business contracts, and medical records.
Our US–Thai Treaty of Amity Certification workflow runs in six clear stages: (1) receive originals and copies, (2) QA-audit the source for issues that would cause rejection, (3) translate through a native-speaker linguist, (4) certify with the authority required by the receiving country, (5) file and follow up at each government touchpoint, and (6) deliver plus retain a signed PDF you can re-download for five years. A single Case Officer owns your file end-to-end, eliminating hand-off errors that plague larger firms.
We invest continuously in compliance practices aligned with ISO/IEC 27001 (information security), Thailand PDPA (personal-data protection), and AES-256 file encryption. Every upload runs over TLS 1.3 only. Enterprise and law-firm clients can request an NDA before intake — our legal team signs same-day.
Beyond single-document work, we bundle end-to-end packages for clients preparing multiple certificates at once — e.g. a "moving abroad" bundle (house registration + birth + marriage + diploma + transcript with MFA + embassy) that reduces the number of trips and total lead time versus filing each item separately. Approval remains at the discretion of the receiving authority; contact our team for scope and fees.
What sets us apart is a 15-year direct working relationship with the destination authority — Department of Business Development + US Embassy Bangkok (US Commercial Service) — so we anticipate regulation changes, format tweaks, and queue timing before they hit your case, and brief you in advance. Approval outcomes always remain at the sole discretion of the authority; what we control is document completeness, formatting and lodgement timing.
