Choosing the right Customs FZ · HS 27 · Amata City Chonburi Industrial Estate provider directly impacts the success and turnaround of your case. NYC Visa & Translation has worked with DOEB (Dept of Energy Business) + Excise + EIA mandatory 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 Customs FZ · HS 27 · Amata City Chonburi Industrial Estate 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 Customs FZ · HS 27 · Amata City Chonburi Industrial Estate 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 — DOEB (Dept of Energy Business) + Excise + EIA mandatory — 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.

First-party answers on the 180-day Thai tax residence test, foreign-sourced income remitted into Thailand, personal and corporate filings, statutory accounting under the Accounting Act B.E. 2543, and claiming double tax agreement relief — grounded in the Revenue Code and Revenue Department guidance. General information only, not a case-specific tax ruling. Our staff quote fees per matter by phone, LINE or email. (19+ search topics covered)
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).
Claiming DTA relief usually requires a Certificate of Residence (R.O.22) from the Thai Revenue Department together with consistent income evidence, and the translation often has to be certified before use abroad.
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.
Tax residence, treaty relief, and foreign tax credits are separate mechanisms; using the wrong one leads to double taxation.
| Route | When to use | Certifying authority | Approx. duration | Rejection risk |
|---|---|---|---|---|
| Certificate of tax residence (R.O.21 / R.O.22) | You must prove Thai tax residence to a foreign tax authority | The Revenue Department | Variable, depending on how complete your filed returns are | Missing returns for the referenced year block issuance |
| Claim relief under a double tax agreement | You earn income from a country with a treaty with Thailand | The Revenue Department and the counterpart tax authority | Variable, per the mechanism that country applies | Assuming a treaty exempts all tax — most allocate taxing rights or grant a credit |
| Refund of over-withheld tax | Withholding exceeded the treaty rate | The tax authority of the withholding country | Highly variable — often several months | Missing the refund filing deadline forfeits the claim |
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.
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. |
