I went to submit my TM47 today to Sa Kaeo immigration in Aranyaprathet. I had all my copies of the required documents signed and ready plus my 1900B. After 30 minutes I was leaving with my 30 day extension stamped in my passport not the Under Consideration I expected. I entered visa exempt on 18-Jul via the Phuket Sandbox. Another thing was I didn't have to sign a STM7 Overstay form which I was expecting.
