Invitation Letter Certification in Thailand
An invitation explains the host, purpose and visit; it does not guarantee a visa. Check whether notarization is actually requested and who may sign before booking.
Certification scope and key checks
Family, conference and business invitations should state the relationship or activity, dates and accommodation accurately. Distinguish the host from the person paying costs. Do not promise full funding if that is not true or invent travel details to make a letter appear persuasive.
For company invitations, check representative authority and signing conditions rather than assuming any director may sign. Personal invitations use host evidence required by the authority. Avoid attaching unnecessary personal-document copies.
Some authorities may request notarization in particular situations, but it is not mandatory for every visa category. Certification performs the stated act; it does not ensure visa approval or entry. Thai and foreign applications must follow the responsible embassy or application system’s current checklist.
Documents to prepare
- Draft invitation and the receiving visa authority’s checklist
- Requested host, relationship or event evidence
- Company signing-authority evidence for corporate invitations
Procedure for this document
- Confirm the application category and whether certification is requested
- Review content, cost commitments and the signatory
- Execute or certify according to confirmed instructions and attach only required evidence
Overseas use: confirm the recipient’s route
Notarization is not required for every public record, and some uses need no onward legalisation. Confirm whether the recipient needs an original, copy, translation or specific certification before arranging MFA and embassy steps where applicable.
Thailand deposited its accession on 30 June 2026. The Apostille Convention is scheduled to enter into force for Thailand on 28 February 2027. Do not assume Thai Apostilles are available before then. Even after entry into force, document scope and treaty relations with the destination must be checked.
Questions before booking
- Does an invitation guarantee a visa?
- No. The authority assesses the applicant and the complete evidence. An invitation or notarization does not guarantee approval or entry.
- Must every invitation be signed before a notary?
- No. Check the authority’s checklist. If witnessed signing is required, follow that form rather than adding certification the recipient does not request.
- Are MFA and embassy legalisation always needed?
- No. Ask the recipient to confirm the certification, language and onward steps. Notarization, translation and legalisation are distinct; do not perform every step automatically.
- How are fees and timing assessed?
- After reviewing the form, copies, signers, language and onward steps, we provide a quote and indicative schedule before work. Authority queues and outcomes are not guaranteed.
- What should I send before booking?
- Send the record type, destination country, receiving authority and its checklist through a direct contact channel. Redact personal information unnecessary for the initial enquiry.
