Direct answer
Thailand's ‘other’ or specialist routes are not one catch-all visa. Expert assignments, volunteer or foundation work, NGO activity, technical cooperation, judicial participation, government projects and other special purposes can fall under distinct Non-Immigrant or official subcategories. The true activity, sponsoring entity and separate approvals determine the route.

Other visas: routes and subtypes covered
Specialist visa routes for government meetings, TICA, Peace Corps, former Thai nationals, court proceedings, diplomatic household staff and unpaid voluntary work. The list below separates the current options that sit within this service family; the route code is F / O. Each option still requires its own purpose, stage and filing-location check.
- Attend a meeting with a Thai government agency — Financial evidence of at least THB 30,000
- Participate in a Thailand International Cooperation Agency (TICA) programme — Financial evidence of at least THB 30,000
- Peace Corps for US ordinary-passport holders — Financial evidence of at least THB 30,000
- Former Thai national who relinquished Thai citizenship — Financial evidence of at least THB 30,000
- Contestant or witness in judicial proceedings — Financial evidence of at least THB 30,000
- Diplomat’s housekeeper — Financial evidence of at least THB 30,000
- Unpaid voluntary work with a government agency or state enterprise — Financial evidence of at least THB 30,000
- Unpaid voluntary work with a Thai-registered foundation or association — Financial evidence of at least THB 30,000
- Unpaid voluntary work with a foreign foundation or association authorised to operate in Thailand — Financial evidence of at least THB 30,000
Documents and practical preparation
The starting document is a role-and-authority map: what the applicant will do each day, whether compensation or benefits are provided, who directs the work, the Thai entity's registration and mandate, project dates and funding, and which ministry, regulator, professional body or court recognises the activity. Invitations should match operational facts.
If volunteering is unpaid, can I do it under any existing visa?
Unpaid work can still be work for immigration and labour purposes; charitable intent does not create an exemption. A foundation's registration does not automatically authorise every foreign role. Professional licensing, site permission, safeguarding, criminal checks or work authorisation may apply in addition to the visa.
TVC's practical assessment
For a specialist case, the job description is a legal document in disguise. We replace ceremonial titles with daily verbs, then test every verb against sponsor authority and approval. That process often reveals that one project needs two phases or that a conventional work route is cleaner than a loosely defined special purpose.
