Quick question. When I go to Jomtien immigration next week to submit documentation for 12-month extension to non-o (retirement) forms TM7 & TM8 (multi re-entry), will everything be done the same day or will I need to return for the stamp in the passport? I did ask this question when I went to get the forms but, despite the sign above the desk being INFORMATION, I was told that they don’t answer questions, just give out forms & queue numbers.
