Frequently asked questions
- What is the DTV and who realistically qualifies?
- The Destination Thailand Visa is a five-year multiple-entry visa allowing stays of up to 180 days per entry, extendable once per entry by a further 180 days at an immigration office. It targets remote workers employed or contracted outside Thailand, freelancers with foreign clients, and participants in Thai soft-power activities such as Muay Thai training, cooking courses or medical treatment, and it requires evidence of the current official rate in available funds.
- How is the LTR visa different from the DTV?
- The Long-Term Resident visa is a ten-year visa administered by the Board of Investment for wealthy global citizens, wealthy pensioners, work-from-Thailand professionals and highly skilled professionals, and it bundles a digital work permit, a flat 17% personal income tax rate for the skilled-professional category and annual instead of 90-day reporting. The DTV is cheaper and faster but grants no work permit for Thai-sourced work and no tax privileges.
- Can I work in Thailand on a tourist or DTV visa?
- No — any work performed inside Thailand requires a work permit or an equivalent digital work authorization, regardless of where the employer or client is located. The DTV is intended for work delivered to foreign employers and clients; taking on Thai clients or a Thai employer requires switching to a Non-B or LTR pathway with proper authorization.
- What most often causes a Schengen or UK visa refusal from Thailand?
- The dominant causes are weak evidence of ties to Thailand, bank statements that show a sudden unexplained deposit shortly before filing, inconsistencies between the application form and supporting documents, insufficient or non-compliant travel insurance, and an itinerary that does not match the stated purpose. Refusals are recorded, so a re-application must directly address the refusal ground rather than simply resubmit the same file.
