Health insurance conditions for Thai long-stay visas are set by Ministry of Interior and Immigration Bureau notifications for Non-Immigrant O-A and O-X categories, and by the Board of Investment for the LTR visa. Officers check the certificate wording, the coverage period against the requested stay, and whether the insurer is recognised. We review and assemble that evidence.

What we handle

Category mapping

We identify which insurance condition applies to your visa category, because O-A, O-X and LTR are governed by different instruments.

Certificate review

The certificate wording, coverage amounts, exclusions and validity period are checked against the requested permitted stay.

Insurer recognition check

We check whether the insurer appears on the list the immigration office accepts, or whether a foreign insurer certificate needs additional certification.

Translation and assembly

Foreign-language certificates are translated and certified, then assembled with the rest of the application file.

Documents required

  4. 4

    Pack assembly

    Translated and certified evidence is assembled into the submission file.

    Step 4: Pack assembly

Why files get rejected

  • Coverage ending before the end of the permitted stay applied for.
  • Certificate issued in a name spelling that differs from the passport.
  • Foreign insurer certificate submitted without the certification the office asks for.
  • Relying on a travel policy for a long-stay category with its own conditions.
  • Assuming the O-A conditions apply to LTR — the LTR conditions are set separately by the Board of Investment.

Frequently asked questions

คำถามที่พบบ่อย (FAQ)

Do you sell insurance policies?+

No. We are not an insurance broker. We review the certificate you already hold against the conditions applied to your visa category and prepare the evidence pack.

Which visa categories have a health insurance condition?+

Non-Immigrant O-A and O-X are governed by Ministry of Interior and Immigration Bureau notifications; the LTR visa has conditions set by the Board of Investment. Other categories may be asked for evidence depending on the case.

Will a policy from my home country be accepted?+

Sometimes, but the certificate has to state the coverage in a form the officer can verify, and some offices only accept insurers on a recognised list. We check this before you file.

Deep Context and Service Standards

Sourced from the Lawyer Act B.E. 2528 (1985), the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the Personal Data Protection Act B.E. 2562 (2019), the Hague Apostille Convention of 1961, and official publications of the Department of Consular Affairs (MFA).

Firm Overview and Practice Framework

Thai Notary Service is a full-service Thai law office providing document notarization, certified translation, legalization chain management, and international document consultancy. Our team includes Notarial Services Attorneys licensed by the Lawyers Council of Thailand under the Royal Patronage, and we operate offices in Bangkok, Greater Bangkok, and a partner network in every province across Thailand. We serve individuals, expatriates, cross-border couples, students, corporates, multinationals, and government agencies requiring documents with legal effect both inside Thailand and abroad.

All notarial acts follow the Lawyer Act B.E. 2528 (1985) Section 27 read with the Lawyers Council Regulation on Notarial Services Attorneys B.E. 2546 (2003), the sole legal basis authorizing Thai attorneys to certify documents comparable to a foreign Notary Public. Every attorney on our team has completed the accredited training and examination administered by the Lawyers Council and holds a verifiable registration number searchable on the Lawyers Council public registry.

By choosing a firm that houses Notarial Services Attorneys in-house, clients consolidate a multi-stage legalization chain under one accountable roof: attorney notarization, followed by Ministry of Foreign Affairs (MFA) legalization at the Department of Consular Affairs, followed by embassy or consular legalization for the destination country. Since 21 November 2024 the Kingdom of Thailand has become a party to the Hague Apostille Convention (Convention of 5 October 1961 Abolishing the Requirement of Legalisation for Foreign Public Documents). Documents apostilled in Thailand are now accepted in more than 125 member states without embassy re-legalization, materially reducing turnaround time and cost.

General Information and Firm Framework — Deep Context

The firm operates under an ISO 9001:2015 quality-management framework and enforces data protection consistent with the Personal Data Protection Act B.E. 2562 (2019). All client documents are stored with AES-256 encryption at rest and in transit and are retained for ten years in accordance with lawyer-record obligations under the Lawyer Act.

Our team combines Notarial Services Attorneys, NAATI-certified translators, and legal specialists in intellectual property, taxation, cross-border family law, corporate law, and immigration law, together with a support team dedicated to documentation, translation, and government-agency liaison.

Fees are transparent and disclosed both on the website and in the pre-engagement quote, separating professional fees, government fees, travel disbursements (if any), and other line items. The firm issues VAT invoices and official receipts and accepts payment by bank transfer, credit card, PromptPay, and cash.

Trust Standards — PDPA, SLA, Quality Assurance

On data protection, the firm strictly follows the Personal Data Protection Act B.E. 2562 (2019), Sections 24, 26, and 27 — collecting, using, and disclosing personal data only to the extent necessary for the engagement, disclosing purposes, and obtaining consent from data subjects in advance. Clients retain the right to inspect, obtain a copy, rectify, erase, or withdraw consent at any time through the firm's Data Protection Officer (DPO). For clients in the European Union, processing follows GDPR Article 6 (lawful basis) and Article 46 (Standard Contractual Clauses).

Our Service Level Agreement targets an inquiry response within one hour during business hours (09:00–18:00, Monday to Saturday), attorney appointments within twenty-four hours, standard notarization within one business day (or two to three hours on express service), certified translation within three to five business days per ten A4 pages, MFA legalization within two business days on standard service (one business day express), and embassy legalization typically within three to fifteen business days depending on the mission's own policy.

Every deliverable passes a three-tier quality-assurance chain: (1) the responsible attorney or translator, (2) a Senior Attorney or department head reviewing substance and formatting, (3) a Quality Control desk performing the final pre-delivery check. Any firm-side error is remedied at no additional cost, and if a document is rejected by a government authority due to a firm-side error, we cover the entire re-filing fee.
