Certified Thai apostille translation with notarization and apostille

Apostille requirements can differ depending on where you are submitting your documents, but accuracy is non-negotiable everywhere. Our team specializes in Thai-to-English and English-to-Thai certified translations for immigration filings, corporate transactions, academic admissions, and cross-border legal matters. Each translation is prepared on company letterhead with a signed translator’s certification, meeting USCIS and international standards.

We are more than a translation vendor—we’re a single partner for the complete process. After translation, we notarize the translator’s affidavit and arrange apostille certification from the appropriate Secretary of State office in the U.S. For countries under the Hague Apostille Convention, the apostille makes your document valid abroad without further legalization. For non-Convention destinations, we can coordinate consular legalization instead.

Quality and consistency matter when dealing with Thai script and transliteration. Our linguists follow standardized conventions (such as RTGS when required) and ensure names, dates, and reference numbers match passports and supporting records. We mirror the formatting of the source document, preserve seals and annotations, and add translator notes where necessary to maintain clarity for reviewing officers.

With global acceptance as a priority, we maintain strict quality control—two-step review, terminology management, and secure data handling. As an ATA member with BBB A+ principles, we focus on compliance and client satisfaction.

Our end-to-end workflow saves you time and avoids multiple vendors. Step 1: Professional translation. We deliver certified translations within 24–48 hours for most standard documents. Step 2: Notarization. We notarize the translator’s affidavit the same day to meet apostille requirements. Step 3: Apostille. We submit to the appropriate Secretary of State for apostille certification. Delivery options include standard mail or expedited courier, depending on your deadline.

Timelines vary by state and season. Translation typically takes 1–2 business days, notarization is same-day, and the apostille process generally ranges from 1–3 weeks. If you already have an apostilled Thai document and only need a certified translation, we can translate and certify it for immediate use. If you need an apostille for a translated document, we will coordinate the filing and return delivery.

Pricing is transparent. Certified translations start at $32.90 per page (USCIS-compliant) or $0.06 per word for standard translations. Notarization and apostille certification involve separate government and handling fees, which we quote upfront based on the issuing U.S. state and your chosen shipping method. There are no surprise charges—only clear, itemized costs.

Kings of Translation serves international moves, cross-border adoptions, study programs, mergers and acquisitions, and more. Whether you are filing with USCIS in the United States or submitting to authorities abroad under the Hague Apostille Convention, our one-stop solution reduces stress. For identity documents that commonly accompany apostille requests, we also provide passport translation.

We translate and apostille a wide range of personal and corporate documents. Common personal records include birth certificates, marriage certificates, divorce decrees, court rulings, police clearance certificates, medical records, vaccination cards, and bank statements. For academic cases, we translate diplomas, transcripts, degree certificates, and enrollment letters for universities and professional boards worldwide.

For business and legal matters, we handle articles of incorporation, powers of attorney, corporate resolutions, bylaws, tax filings, contracts, and certificates of good standing. We preserve formatting, tables, and seals so that officials can easily compare translations with originals. Where needed, we add translator notes to explain stamps, hand-written annotations, or partially illegible seals.

Thai-specific considerations include handling names with consistent transliteration across multiple documents, verifying address formats, and aligning dates when Thai Buddhist Era notation appears. Our linguists confirm that the English rendering of Thai names matches the passport’s English page to avoid delays. If an agency requires a specific transliteration system, we follow it precisely.

If your destination country is not part of the Hague Apostille Convention, we’ll guide you through consular legalization instead of apostille. Our project managers coordinate every step, from translation through notarization to the appropriate legalization authority, ensuring you submit the correct paperwork on the first attempt.
