TLDR : Answer Summary
If you're looking to extend your 60-day visa in Thailand for the first time, here are some helpful tips from the community: 1. Prepare the necessary documents: Bring your passport, a completed TM7 form, a TM30 form (proof of accommodation), a passport-sized photo, and 1,900 THB in cash. 2. Arrive early: Long queues can make the process lengthy, especially at busy immigration offices like Chaeng Wattana. 3. Dress appropriately: Avoid casual attire such as flip-flops or tank tops when visiting government offices. 4. Consider using a visa agent: They can simplify the process and reduce stress, particularly for first-timers. 5. Be patient and calm: The immigration process can be slow, so bring a book or your phone to pass the time. 6. Know your visa status: Understand whether you are on a 60-day tourist visa or a visa exemption, as this affects where you need to go for your extension.
