Emergency landings, humanitarian aid flights, medical or relief flights, repatriation and cargo flights, state or military aircraft, and technical landings without disembarkation may still enter the country. To enter Thailand, all travelers must have a fit-to-fly health certificate, a medical certificate indicating that they have tested negative for COVID-19 (RT-PCR test) within 72 hours before departure, either (a) a certificate from their parent agency/authority confirming that it will cover all medical expenses OR (b) proof of health insurance covering all medical expenditure, including for COVID-19, up to USD $100,000 minimum, and a Certificate of Entry issued by the Ministry of Foreign Affairs. Travelers suspected of carrying COVID-19 may be denied entry into the country. In addition to the above, permanent residents or work permit holders and their family members, students, and those seeking medical treatment must have a Certificate of Entry issued by the Royal Thai Embassy or the Royal Thai Consulate-General in their country of departure to enter Thailand. Travelers with an urgent need to travel to Thailand should contact the Thai embassy or consulate in their country of departure at least 10 working days before their proposed date of travel to explain their circumstances. They will also need to provide a copy of their confirmed booking at an ASQ hotel, and either a copy of their work permit (if it is already expired, the employer should contact the Ministry of Labour to issue a WP3), a copy of letter of permission to work in Thailand from a Thai government agency (such as the Ministry of Labour, the Ministry of Education, BOI) or a copy of the Certificate of Residence. All travelers to Thailand are required to complete 14 days quarantine at a State Quarantine or Alternative State Quarantine (ASQ) facility.
