Choosing the right Non-B BoI Extension (One Stop Service) · Chinese passport (PRC) provider directly impacts the success and turnaround of your case. NYC Visa & Translation has worked with Immigration Bureau 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 Non-B BoI Extension (One Stop Service) · Chinese passport (PRC) 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 Non-B BoI Extension (One Stop Service) · Chinese passport (PRC) 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 — Immigration Bureau — 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.

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.

The Foreign Business Act B.E. 2542 groups activities into Lists 1–3 with different conditions. Define the real activity first, then pick the route: licence, certificate, treaty right, or a BOI promotion certificate.
Affidavits, financial statements and powers of attorney usually need notarisation abroad, government or embassy authentication, then Thai translation and legalisation by the Legalization Division, Department of Consular Affairs.
A promotion certificate carries incentives and shareholding conditions that differ from an ordinary company. Compare minimum investment, technology and employment conditions per activity before committing.
Objectives registered with the Department of Business Development must cover the licensed activity. A mismatch forces an amendment of the affidavit first, typically costing weeks.
Most licences require periodic reporting, renewal or notification of changes. Missing these can lead to revocation even when the business operates normally.
Parent-company affidavits and powers of attorney often have a validity period from issue. A slow legalisation chain can expire them before filing, forcing a fresh set.
Holding shares on behalf of a foreigner without genuine investment breaches the Foreign Business Act, and the source of Thai shareholders' funds can be examined. We do not assist with such structures.
Many licences involve a site visit. Filing without signage, floor plans or required sanitation results in a correction order and a new inspection date.
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.
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.
A visa outcome is the consulate's discretion, so judge a provider on process, not promises. Reliable providers state the current published requirements of your destination, prepare a file that matches them, explain what happens if the consulate asks for more, and never claim guaranteed approval. Anyone promising a result is describing something they do not control.
| Option | Best for | What to know |
|---|---|---|
| Apply yourself | Straightforward profiles with complete documentation | You carry the burden of tracking requirement changes and appointment slots. |
| Document-preparation service | Applicants with complex financial or employment evidence | Confirm whether appointment booking is included in the scope. |
| Full handling including appointments | Families and deadline-bound travel | Biometrics and interviews still require the applicant in person. |
