Can I apply for a 60-day COVID extension if I enter Thailand on a visa exempt for 30 days?

If you enter Thailand on a 30-day visa exemption, you can apply for a 60-day COVID extension, but you need to have received a first extension of stay based on tourism, which must be done before November 26, 2021. It is important to note that a standard tourist visa allows for a 60-day stay from entry with the possibility of a 30-day extension, without needing specific COVID-related justifications.
