I have lived in Thailand for many years and attempted renewing myself only to be told the rules had changed. Then tried two visa companies. One lied to me regarding changing my visa status and charged me accordingly. Another told me to travel to Pattaya at my expense. However my dealings with Thai Visa Centre have been a very simple procedure. I was informed regularly on the process status, no travelling, only to my local post office and a lot less demands than doing it myself. Highly recommend this well organised company. Well worth the cost. Many thanks for making my retirement more enjoyable.
