When does the extension start when applying for a visa extension in Thailand?

The conversation discusses the process and timing of extending a 60-day visa exemption in Thailand. It clarifies that the extension period is added to the end of the original visa period, meaning that applying for the extension before the 60 days expire does not cause any loss of days. Various comments confirm that extensions can typically be applied for up to 15 days early without affecting the start of the new extension period, with anecdotal experiences differing slightly by location.
