TLDR : Answer Summary
Recent reports from Phuket immigration indicate that visa extensions are now only issued on the expiration date, aiming to reduce overcrowding at immigration offices. This change particularly affects standard Tourist Visas being extended for the first time. If individuals are unprepared with their documentation, they may face penalties for overstaying. Required documents for a 30-day extension include a passport, copies of the passport's front page and visa page, a TM6 form, a completed TM7 form, two photos, and a fee of 1,900 Thai Baht. Additionally, a TM30 form is required in Phuket.
