"The Royal Thai Government officially approved a grace period until October 31, 2020 for persons in Thailand in temporary visa status (of all visa types) to depart the country. In light of this decision by the Royal Thai Government, visa extension letters from the U.S. Embassy are not required to remain in Thailand. According to verbal communication from the Royal Thai Government’s Immigration Bureau, non-Thai nationals can visit any Thai Immigration office to request a 60-day extension of stay past the October 31 amnesty. We have been told that there will be a charge for this. Thai Immigration will not require a letter from the Embassy as part of the extension request, so the U.S. Embassy and Consulate General Chiang Mai will no longer provide letters of support for Thai visa extensions.
