How soon can I apply for a 30-day extension after receiving a 60-day visa exemption in Thailand?

The timing for applying for a 30-day extension to a 60-day visa exemption in Thailand varies by location. Most immigration offices allow applications when there are 30 days or fewer remaining on your current visa stamp. Some larger offices, such as those in Bangkok, Phuket, and Chiang Mai, permit requests when you have 45 days or fewer left, while others, like in Koh Samui and Pattaya, require that you have only 7 days or less remaining. As for timings, the discussions indicate that it's quite early for anyone to have tried this since the 60-day visa exemption has only been recently introduced, making it unlikely that anyone has done so yet.
