What this page covers

The e-Visa portal lists diplomatic and official missions as a separate category. It is intended for applicants travelling under a recognized diplomatic, governmental, international-organization or official-mission purpose, not for ordinary business travel.

Official classification

Diplomatic visa for qualifying diplomatic missions
Official visa for qualifying official missions, postings or approved international-organization duties
Related non-immigrant F classifications can apply to some government or international-organization activities

Prepare the application carefully

Use the official Thai e-Visa portal to select the live visa category for the passport/travel-document country and current application location.
Applicants must be outside Thailand when applying through the e-Visa process. Do not start from an assumption that a visa is available solely because a category appears in a general list.
Create the e-Visa account, complete the form accurately, upload the documents requested for that exact route, pay the applicable fee and keep the approval confirmation sent by email.
Passport or travel document appropriate to the mission and photograph
Official note, diplomatic note or mission letter that identifies the purpose, applicant and period
Posting, organization or government documentation requested by the responsible Thai mission
Family/dependant evidence where a qualifying family member is included

Visa, entry and stay are separate decisions

Issuance and entry permission remain subject to the responsible Thai authorities. The correct category is determined by the official mission purpose and supporting documentation.

Activity boundary

An official or diplomatic route must not be used for private tourism, ordinary commercial work or a purpose outside the sponsoring mission. Contact the responsible Thai mission through official channels for the live checklist.

Known developments and changes to watch

No category-specific rule change was found in the official sources reviewed for this page on 14 July 2026. Thailand’s Visa Policy Review Committee met on 30 June 2026 and was asked to develop future proposals, but that meeting did not itself create a new visa rule. Only an official notice with an effective date changes the applicable requirements.
