How much does Specialized / Technical Translation cost?
Contact staff for a tailored quotation based on documents, language and recipient requirements. Official authority fees are separate from company service fees.
How long does Specialized / Technical Translation take?
Standard turnaround is 2 – 5 business days. Express service can cut this in half (additional fees apply).
Do I have to visit the office?
No — NYC Visa picks up/delivers nationwide via Kerry/Flash/EMS. You only need to send a copy of your ID and a Power of Attorney.
What document types do you handle?
We cover 12+ document types: Clinical study report, Medical journal article, Drug label & IFU, Engineering manual, Machinery operation manual, Patent specification and more. Contact 083-249-4999 for special cases.
Which authority certifies Specialized / Technical Translation?
NYC Visa Specialized Translation Center — expert translator network by domain is the official body. NYC Visa acts as your authorized representative per government procedure.
Do you serve other provinces or overseas clients?
Yes — 77 Thai provinces plus 60+ countries internationally. Contact LINE @NYCT or WhatsApp +66815620444.
Where can the certified document be used?
Worldwide. For Hague Convention countries, Apostille applies (Thailand is not yet a party). For others, MFA Legalization + destination embassy procedure applies.
Is there a guarantee?
No. NYC Visa checks every file before delivery, but does not offer refunds; the final decision rests with the receiving authority.
How can I pay?
Bank transfer (KBank/SCB/BBL), Visa/Master, PromptPay, or cash at our office. Tax invoice in your company name is available.
A certified translation carries a signed accuracy statement, the translator's or agency's name and contact details, the date, and a seal. For government use it must also survive MFA review, which checks name spelling against the passport, date formats and reproduction of every stamp on the source page — including the small overlap seals people often omit.
Do you translate the stamps and handwritten notes too?
Yes, and this is where most rejections happen. Every seal, registrar signature block, overlap stamp and handwritten annotation is rendered in the translation with a bracketed descriptor. A translation that reproduces only the printed text reads as incomplete to a consular officer and is sent back for revision.
Which language pairs do you cover?
Thai, English, Chinese (Simplified and Traditional), Japanese, Korean, Russian, Arabic, German, French and Hindi, both directions. Legal, medical, financial and technical subject matter is assigned to translators with domain experience, because terminology consistency across a document set is what receiving authorities notice first.
How do you keep terminology consistent across a large bundle?
Each client gets a locked glossary: name transliterations, company names, job titles, address forms and document titles. Every subsequent job reuses it. This matters for immigration bundles where the same employer name appearing three different ways across payslips, an employment letter and a tax record triggers a document integrity query.
Certified translation in Thailand — questions clients actually ask
First-party answers on language coverage, Thai civil-registry documents, translator certification, MFA legalisation and onward embassy attestation. (53+ search topics covered)
Do certified translations expire?
The translation itself has no fixed validity, but many authorities require the underlying document (single-status certificate, company affidavit) to be issued within the last three to six months. Check the receiving authority's rule before translating.
Can Thailand issue an Apostille?
Thailand deposited its instrument of accession to the 1961 Apostille Convention on 30 June 2026, and the Convention enters into force for Thailand on 28 February 2027. Until that date Thai documents still follow the two-step route: legalisation by the Department of Consular Affairs, then legalisation by the destination country's embassy in Thailand. Until then, Thai documents follow the traditional chain: MFA legalisation, then destination-embassy attestation.
What makes a translation "certified" for Thai official use?
In Thai practice a translation is accepted when it is complete, faithful to the layout of the original, and accompanied by the translator's declaration with name, signature and contact details; for consular use the translator's signature is then certified by the Department of Consular Affairs. Some foreign authorities additionally require a sworn or court-appointed translator of their own country, which is a separate requirement we identify before starting.
Can everything be handled remotely?
Translation and proofreading can be handled from high-resolution scans of every page, including stamps and signatures. Legalisation requires physical originals, so those must be couriered in or filed by an authorised representative.
How long does the process take?
Translation itself is usually a few business days depending on volume and language pair. MFA legalisation has both standard and express channels with different cut-off times and fees — check the Department of Consular Affairs website for current schedules before booking a visa appointment.
Which romanisation of a Thai name should a certified translation use?
Always follow the spelling in the passport, even where it differs from standard transliteration, because receiving authorities check against the travel document first. If older records use a different spelling, ask the translator to add an explanatory note, and in some cases obtain an official same-person certificate. Never silently change a spelling inside the translation: that makes the text diverge from the source and undermines the certification.
Company documents for use abroad — what is needed?
Typically a current company affidavit from the Department of Business Development, plus the shareholder list and memorandum of association if the destination requests them. All should be registrar-certified copies before translation and legalisation.
Foreign documents used in Thailand — what is the route?
The document is normally authenticated in the issuing country and attested by the Royal Thai Embassy or Consulate there, then translated into Thai and submitted for translation legalisation at the Department of Consular Affairs in Thailand.

Certified translation — documents, steps and pitfalls
Before translating anything, identify the certification system the receiving authority accepts: NAATI (Australia), sworn translators (Germany, France, Spain, Italy), certified translation with a Certificate of Accuracy (US/UK), or a Ministry of Justice registered translator for Thai courts.
Documents to prepare
• Original or freshly issued certified copy from the issuing authority (not a photocopy)
• Passport copies of every person named, so spellings match exactly
• Any written requirement from the receiving body (university, embassy, employer)
• A list of preferred spellings for names of companies, temples or villages
• Power of attorney if someone else handles the process for you
• High-resolution colour scans for the pre-check before originals are sent
Step-by-step process
1. Confirm destination and system — Tell us the country, authority and purpose so the correct certification route is chosen from the start.
2. Pre-check the source document — Validity, seals and name spelling against the passport are verified before translation begins.
3. Translate and double-review — A translator plus an independent reviewer check figures, dates and official body names.
4. Issue the certification — A Certificate of Accuracy is attached, or the file is routed into the sworn/NAATI system required.
5. Continue the legalisation chain — For foreign government use, the file continues to the Department of Consular Affairs and the destination-specific step.
Pitfalls and rejection causes
• Name spelling that differs from the passport is the number one cause of rejection.
• Self-translation or a provider outside the accepted system is usually refused even when accurate.
• Do not unstaple or rebind a certified set — broken cross-page seals invalidate it.
• Some documents have a short acceptance window; plan backwards from your appointment date.
Tips from our team
• Agree on the English names of Thai authorities up front to avoid follow-up queries.
• Keep one spare certified set before submitting anything.
• If several countries are involved, say so early so one original set can serve all of them.
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.
Route Comparison
Which certified-translation format will be accepted
"Certified translation" does not mean the same thing everywhere — each receiving body accepts a different format.
Thai documents going to a foreign authority via its embassy
Department of Consular Affairs, MFA Thailand
Variable, depending on queue and submission channel
A layout that does not match the consular template is refused at the counter
Translation by an accredited/sworn translator abroad (NAATI, sworn translator)
Destination is Australia or a sworn-translator jurisdiction
That country's accreditation body, e.g. NAATI
Variable, usually a few working days
Using a translator whose accreditation lapsed, or a translation without the stamp/registration number
Translation certified by a notarial services attorney
The receiving party is private — a university, employer or overseas bank
Attorney licensed by the Lawyers Council of Thailand
Usually same day to a few days
Many foreign government bodies will not accept this in place of consular legalisation
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.
Advisory Service
We do not just process documents — we advise you through the whole 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.
Route assessment
We look at your destination, purpose and deadline, then tell you which certification route applies — and which steps you can skip.
Pre-submission review
Name spelling, consistency across documents, document age and translation format are checked before anything reaches a counter.
Timeline planning
We sequence the steps around your appointment or travel date and flag bottlenecks in advance.
Rejection recovery
We read the refusal reasons, identify the underlying cause, and plan a resubmission that answers what the authority asked for.

Practical Q&A
Practical questions · Near me / DIY / Required documents
How do I find certified translation near me?
Our only office is at Ladprao 95, Bangkok. Send clear scans through LINE @nycvisa with the destination country, receiving authority and required date. We will confirm the translation format and whether originals or delivery are needed before you send documents.
Can I translate it myself and have it certified afterwards?
It depends on the recipient. The Department of Consular Affairs certifies a translation by checking it against the original rather than by translator identity, but many embassies and foreign authorities require an independent or accredited translator. Check the destination's rule before self-translating to avoid a rejection cycle.
What do you need from me to start?
Sharp colour scans of every page including seals and signatures, the English spelling of names exactly as printed in the passport, the receiving authority and country, and your deadline. Sending any previously certified translation helps keep terminology and name spelling consistent across the set.
Practical advice & cautions
Document translation: what to prepare and what gets rejected
Before you start
Tell us the fixed terms
Company names, institution names, academic titles and drug names should follow the English form already used in your other filings so the whole bundle stays consistent.
Sequence the steps so originals stay valid
When translation, certification and apostille or embassy steps are chained, allow for each authority's queue and start with the longest step so the underlying original does not age out.
Name the destination authority before choosing a translation type
Certification systems are not interchangeable. Australian authorities require NAATI-certified translators, while documents used inside Thailand or filed at embassies in Thailand usually need translation certification by the Department of Consular Affairs. Tell us the receiving authority and country first.
Match the passport spelling exactly
Translations must reproduce the given name and surname exactly as printed in the passport you will submit, not a fresh transliteration. Always send the passport bio page together with the documents.
Common reasons documents get rejected
Leaving page elements untranslated
Seals, signatures, reverse-side text and marginal notes must all be rendered or described. Omitting them is one of the most common rejection causes.
Inconsistent names across the bundle
If you have changed your name or used different spellings, include the official name-change certificate and its translation; otherwise the authority may treat the documents as belonging to different people.
Self-translated documents
Most authorities refuse translations produced by the applicant or a relative, even if accurate, because there is no identifiable certified translator behind them.
Submitting the translation without the source copy
Many authorities require the source document to be attached to each translated page so the text can be verified. A standalone translation is usually returned.
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.
What people search for
Frequently searched topics about certified translation
NAATI translation for Australia
Australian authorities generally require a certified translator's stamp and practitioner number on the translation.
Certified translation for legalisation
Translations submitted for legalisation must mirror the original line by line, including seals and signatures.
Name spelling matching the passport
Names must match the passport page character for character; a single-letter difference is a common rejection reason.
Thai to English translation for embassies
Each embassy sets its own accepted translator and certification format; request the requirement in writing first.
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.
Choosing a document translation provider in Thailand
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.
How to evaluate a provider
The certifier is named and identifiable — Consular offices and embassies check who certified the translation, not only the wording.
Knows the format the destination accepts — Each embassy differs: attached source copy, letterhead, or prior consular legalization.
Character-level verification — Mismatched name spelling and dates against the passport is the most common rejection cause.
Owns corrections after rejection — Submissions run on appointment dates; slow corrections cost the applicant the slot.
Documented custody of originals — Some civil registry documents are hard to reissue, so intake and return must be traceable.
Questions to ask before you commit
How can I track status, and who physically holds the original documents?
Who will certify this translation, and will the certifier be named on the document?
Does my destination require consular or embassy legalization afterwards?
How many working days does it actually take, counted from a complete file?
If the receiving authority rejects or asks for changes, do you correct it, and under what terms?

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.
FAQ on choosing a provider
Which translation service is recommended for embassy submissions?
Choose one that names the certifier on the translation, knows the exact format your embassy accepts, and verifies names and dates against the passport before certifying. Ask whether they also handle consular legalization so the file does not stall between two vendors.
Does a cheaper translation get rejected more often?
Rejection correlates with format and verification, not price. A translation is rejected when the certifier cannot be identified, the layout does not match the receiving office's requirement, or a name or date differs from the passport.
