Related Translation & Interpretation

Foreign documents need Apostille (HCCH) or Thai-embassy legalization, then MoJ-registered translation and MFA Consular certification — ILC handles the full stack in one package.

Post-Service Policy

If a document is rejected due to a defect in our drafting, translation, or certification, we redo and resubmit at no extra service fee (government fees excluded). This is service responsibility, not a guarantee of any official outcome.

In-Depth Guide: Certified Translator Affidavit & Stamp Block (MOJ-AFF)

Certified Translator Affidavit & Stamp Block is delivered under ILC's APEC, Medical Council, MoJ Translator and Degree Equivalency practice, combining MoJ-certified translation, MFA legalization, embassy liaison, and Thai government filing under one project manager. Every case is handled by a NAATI-accredited translator, a Thai Notarial Services Attorney, and a dedicated case coordinator.

Cross-border professional recognition in Thailand runs through four authorities: (1) Department of Business Development for APEC Business Travel Card (ABTC), (2) Medical / Nursing / Pharmacy / Dental Councils for verification letters used in overseas licensing, (3) Ministry of Justice registrar for translator and interpreter accreditation, and (4) Office of Higher Education Commission (OHEC) for degree equivalency. ILC prepares the complete package for each: ABTC eligibility routing (Trade, Business, Executive, Airline Crew), Medical Council PBP (Professional Behavior Profile) with fitness statement, MoJ translator listing renewal every 2 years, and OHEC equivalency reports for foreign degrees used in Thai employment or civil service. Each pathway has its own document set and processing timeline, ranging from 3 weeks (MoJ translator renewal) to 4 months (APEC card issuance after multi-economy approval).

Why choose ILC for Certified Translator Affidavit & Stamp Block

With more than 15 years of practice, ILC covers every embassy in Bangkok and both MFA offices (Chaengwattana and Chiang Mai). We operate a two-tier QA review and refund the service fee if a document is rejected due to a defect in our translation or certification — government fees and officer discretion excluded.

FAQs about Certified Translator Affidavit & Stamp Block

คำถามที่พบบ่อย

Who is eligible for ABTC?

Executives, business owners, and airline crew of companies actively trading with APEC economies.

Is the MoJ interpreter list public?

Yes and courts pull directly from it when appointing interpreters.

Does OHEC recognise online degrees?

Only if the awarding university is on the OHEC-approved list; case-by-case for others.

Can we accelerate ABTC?

APEC approvals depend on each economy's own review; no acceleration is possible for individual economies.

“The Certified Translator Affidavit & Stamp Block files we see most often are ones the applicant filed themselves and got rejected for an outdated template or a passport-name mismatch — that's why we audit every document before touching translation.”

A working guide to Professional Credentials in Thailand

Professional Credentials is one of the standing service lines that corporate legal departments, embassies, foreign universities, HR compliance teams, and immigration bureaux route their highest-stakes files to. The institutional posture — as opposed to a freelance translator or a generalist firm — is the deliberate reason receiving offices treat the deliverable as finished, not draft. Every Professional Credentials matter is scoped by a senior specialist on LINE Official @NAATI or by email at ilc@thainotary.co.th before any file moves.

How the workflow runs end-to-end

For matters that touch multiple counters — Amphur District Office, DBD, DIP, BOI One Stop, or the Criminal Records Division of the Royal Thai Police — a dedicated runner sequences the visits in the correct legal order, so the client is not sent from one office to another chasing missing signatures.

Who this service is for

Foreign missions in Bangkok and international bodies on framework contracts receive a dedicated key-account manager, standardised invoicing on 30-day net terms, and monthly consolidated statements that meet their internal audit format — no bespoke translation project management on their side.

Coverage, fees, and turnaround

Same-day express is offered for filings tied to a flight, hearing, or academic deadline, subject to counter availability at MFA Chaeng Watthana and the destination embassy. The surcharge is quoted before work begins and is not applied retroactively.

Quality assurance and confidentiality

Every certified translation ships with a translator's declaration on our headed paper carrying the linguist's full name, credential number, and dated signature — the format immigration officers, university registrars, and consular staff are trained to accept without follow-up questions.

Start your Professional Credentials matter today

Reach ILC on LINE Official @NAATI, email ilc@thainotary.co.th, or phone 080-5578887. Office hours are Monday to Sunday, 08:30 to 20:00 Bangkok time. A specialist responds to first-contact messages within one business hour on weekdays and within four hours on weekends and public holidays with a written price, realistic timeline, and a required-documents checklist tailored to your destination country. There is no charge for the initial consultation, and no obligation to proceed after receiving the quote — ILCearns repeat business by delivering the first Professional Credentials matter cleanly and on time, not by locking clients into open-ended retainers.
