Written by the Thai Legal & Immigration legal team · Last reviewed · Editorial policy

Unpaid work is still work under Thai law. Volunteers at foundations, associations or international NGOs need a Non-Immigrant O visa sponsored by the organisation and, in most cases, a work permit for volunteer activity issued by the Department of Employment.

The sponsoring organisation must be properly registered and its project approved. We review the organisation's registration and the volunteer's role so the application describes the activity accurately and avoids reserved occupations.

What we handle

  • Sponsor registration and project review.
  • Visa application or in-country conversion.
  • Volunteer work-permit filing.

Counsel's note

Many short-term 'voluntourism' programmes do not provide a lawful basis to volunteer. We check before you arrive.
