How can an American extend a 30-day visa exemption in Thailand?

An American who enters Thailand on a 30-day visa exemption can apply for a 30-day extension at any immigration office for a fee of 1,900 baht. The extension begins from the current expiration date, allowing up to an additional 30 days of stay. Applicants can typically request the extension when they have 30 days or less remaining on their visa; however, some immigration offices may require applicants to wait until they have only one or two weeks left. The specific rules may vary by location, so it's helpful to check the local procedures where you plan to apply.
