What is the current process to extend a 60-day Tourist Visa in Thailand?

To extend a 60-day Tourist Visa (TR visa) in Thailand, one typically needs to present their passport, photographs, and the appropriate fees, alongside a completed application form. Additionally, it is often required to provide copies of the passport, particularly the identification and visa pages. Some places, like Koh Phangan, may also require the TM30 form, which tracks the residence of foreigners in Thailand. It is advisable to check for any specific requirements at the immigration office on the day of the application, as practices may vary.
