How can I extend my 60 Days Tourist Visa in Thailand by 30 days?

To extend your 60 Days Tourist Visa (TR) by 30 days in Thailand, you should go to the Chengwattana Government Office. Required documents typically include a scan of your passport and stamps, a passport picture, completed TM7 form, and a copy of your TM6 form. Additionally, there is a fee of 1,900 baht. While some travelers have been asked for a TM30 form and hotel booking confirmation, it is not mandatory, but it's advisable to get a screenshot from your hotel or ask them to confirm your stay.
