On May 19, 2026, the Cabinet of the Royal Thai Government approved, in principle, revisions to Thailand’s visa exemption scheme and visa on arrival (VOA) program, as proposed by the Ministry of Foreign Affairs and the Ministry of Tourism and Sports. The revisions represent a tightening of Thailand’s immigration framework and will affect a broad range of short-term visitors. Background On July 15, 2024, Thailand expanded its visa exemption scheme by increasing the permitted period of visa-exempt stay from 30 days to 60 days in order to promote tourism, support the country’s post-pandemic economic recovery, and facilitate international travel. Under this revised scheme, passport holders from 93 countries and territories (an increase from the previous 57 countries and territories) have been permitted to enter Thailand without a visa and remain in the country for up to 60 days per entry for purposes including tourism, business engagements, urgent work, and ad hoc assignments. In addition, eligible visitors may apply at the Thai Immigration Bureau for a further 30-day extension of stay. Key Changes The proposed revisions would revoke the current 60-day exemption and reinstate the previous stay period, thereby reducing the maximum permitted stay for eligible travelers to 30 days per entry. In addition, the number of countries and territories eligible under the 30-day visa-exemption scheme is expected to be reduced to 54. The scope of the VOA scheme would likewise be significantly narrowed, with the number of eligible countries reduced from 31 countries to just four (Azerbaijan, Belarus, Serbia, and India). Further, Thailand is expected to introduce a new 15-day visa exemption category for nationals of Seychelles, the Maldives, and Mauritius. The revised framework would also limit each country or territory to a single visa exemption privilege in order to simplify Thailand’s immigration framework and reduce overlapping immigration privileges.
