Prism Linguistics delivers professional Thai translation for US institutions: USCIS, federal and state courts, universities, healthcare providers, and corporate clients. Every project is translated by a native Thai speaker, reviewed by a second linguist for accuracy and terminology, and delivered within 24 to 48 hours for short documents. Certified versions include a signed Certificate of Translation Accuracy on company letterhead, the format USCIS officers and U.S. courts expect.
Need it faster? Same-day Thai translation is available for urgent USCIS deadlines, court filings and business contracts, including weekends. Submit before 2pm EST for same-business-day delivery.
A certified Thai translation is a word-for-word translation of your original document, accompanied by a signed Certificate of Translation Accuracy from the translator or translation company. The certificate confirms the translator's competence and the completeness of the translation. USCIS, U.S. federal courts, U.S. universities, credential evaluators, banks, and most state agencies require certified translations for any non-English document submitted in an official process.
The most common reason USCIS issues a Request for Evidence (RFE) on a translation is a missing or incorrectly formatted Certificate of Translation Accuracy. Every certified Thai translation we deliver includes the certificate on company letterhead with the translator's signature, our corporate seal, and the date: the format USCIS officers, court clerks, and university registrars expect to see.
Looking for a Thai translator in the USA? Prism Linguistics runs one of the larger professional Thai translation teams serving US clients. Most of our Thai requests come from US-based clients who need official Thai documents accepted by an American institution: typically USCIS, a state or federal court, a university registrar, or a healthcare provider. Every Thai translator we assign has direct experience preparing documents for those four destinations.
The Thai translation work we handle in the United States falls into five clear groups:
From a one-page Thai birth certificate translated for a USCIS green-card filing to a 200-page Thai commercial contract reviewed for cross-border litigation, our work spans the full range of Thai to English (and English to Thai) translation that U.S. institutions accept. For projects requiring official certification, see our certified Thai translation service. For document translation across all languages we support, see our broader document translation capability and the full list of supported languages. Read about our company on our About page or browse the organisations we work with.
Thai to English translation is the bulk of our US work. Thai is spoken in Thailand. We translate Thai documents into English for USCIS immigration applications (birth, marriage, divorce, naturalisation), federal and state court filings (depositions, contracts, foreign evidence), academic credential evaluation (transcripts, diplomas, professional licences), and corporate work (contracts, due diligence, regulatory filings). Certified versions are accepted by USCIS, U.S. courts, all major credential evaluators, and U.S. universities.
We translate English documents into Thai for business communication, legal correspondence with Thai-speaking counterparties, medical patient-facing materials, academic publications, and personal documents. Each English to Thai project is handled by a native Thai speaker who currently lives in a Thai-speaking community, so terminology reflects how the language is actually used today, not how it was used in textbooks twenty years ago.
Most Thai translation projects come from one of five sectors. Each has its own conventions, terminology and submission requirements. The translator we assign to a project is chosen for documented experience in the relevant sector, not just for general Thai fluency.

Submit your Thai document through our online quote form, email info@prismlinguistics.com, or call +1 833 282 8883.

Whether you need a Thai translator for a one-page birth certificate or a long-form Thai legal contract, our native Thai linguists handle the work remotely with the same accuracy you would expect from an in-person translator. Every Thai translation is reviewed by a second linguist before delivery, and certified versions include a signed Certificate of Translation Accuracy that USCIS, U.S. courts, and universities accept nationwide.
Translation quality matters when documents are used for immigration, legal, medical, academic, or business decisions. Our process is shaped by what U.S. institutions actually reject: missing certification statements, inconsistent name transliterations, and translator credentials that don't appear on the document. We address all three on every project.
Standard one-page civil documents (birth certificates, marriage certificates, diplomas) are charged on a flat per-page basis from $30 per page, including the signed Certificate of Translation Accuracy.
Longer legal, medical, and technical documents are quoted by word count from $0.12 per word, with a minimum charge of $50 per project.
Optional add-ons: notarisation ($25 flat fee), hard-copy mailing within the US ($15 standard, $35 overnight), and same-day rush turnaround (+50% of base price).
We confirm the full price in writing before any work begins. Request a free quote for your specific Thai document and we will confirm exact pricing and turnaround within one business hour.
Thai is the official language of Thailand, with around 60 million native speakers and another 20 million using it as a second language. In the United States the Thai-American community is around 300,000, concentrated in Los Angeles (Thai Town), the Bay Area, Las Vegas, Houston, and Chicago. Translation work is split between civil documents — Thai birth certificates, marriage records, and household-registration papers for USCIS — and business content tied to the Thai hospitality and restaurant industry that anchors much of the diaspora. Thai is tonal with five tones and uses its own script, an abugida derived from Old Khmer.

“Fast and professional translation service. USCIS accepted our certified translation without any issues.”
“Excellent communication, quick turnaround and accurate legal translation.”
Yes. We provide certified Thai translations specifically formatted for USCIS immigration applications. Each translation includes a signed Certificate of Translation Accuracy on company letterhead with the translator's signature, our corporate seal, and the date. The most common cause of a USCIS Request for Evidence on a translation is a missing or incorrectly formatted certificate, so we deliver the certificate in the format USCIS officers expect to see.
Standard turnaround for short documents like birth or marriage certificates is 24 to 48 hours. Same-day rush is available for urgent USCIS deadlines, court filings and business contracts, including weekends. Submit before 2pm EST for same-business-day delivery.
Standard one-page civil documents (birth, marriage, divorce, school certificates) are charged on a flat per-page basis starting from $30 per page. Longer legal, medical, and technical projects are quoted by word count from $0.12 per word. Certification, notarisation, hard-copy mailing, and same-day rush are optional add-ons. We confirm the full price in writing before any work begins.
Every Thai translation we deliver is produced by a qualified human translator and reviewed by a second human linguist for accuracy, terminology, and formatting. We do not deliver raw machine output. Our translators are native Thai speakers with documented subject-matter experience in the relevant field.
The most common Thai documents we translate are birth certificates, marriage certificates, divorce decrees, school transcripts, academic diplomas, passports and national identity cards, court orders and affidavits, medical records, business contracts, and financial statements. All of these can be certified for USCIS, US courts, and US universities.
Yes. We translate English documents into Thai for business communication, legal correspondence, medical patient-facing materials, academic publications, and personal documents. Each project is reviewed by a second linguist for terminology and clarity before delivery.
Yes. Notarisation is available on request and is sometimes required for state court submissions, certain visa applications, document recording, and international Apostille processes. We can include notarisation with same-day delivery for urgent matters.
We deliver Thai translation services nationwide. Most projects are delivered as digital PDFs that we email anywhere in the United States within 24 to 48 hours. Hard-copy mailing is available to any US address. Our largest client clusters are in New York, Los Angeles, Chicago, Houston, San Francisco, Washington DC, Atlanta, Miami, Boston, Dallas, Seattle, Philadelphia, and Denver.
Yes. Every Thai translation is handled under strict confidentiality. Documents are transferred over secure channels, accessed only by the assigned translator and reviewer, and deleted from our active systems 30 days after delivery on request. Signed Non-Disclosure Agreements are available for legal, medical, and corporate clients on request.
If USCIS, a court, a university, or any other receiving institution requests a clarification or correction to a translation we produced, we revise and re-issue the document at no additional cost. The same translator and reviewer are reassigned where possible, so the correction is consistent with the original.
