I had considered using them a few years ago but decided not to since their price was way to high plus when they said I did not need any back up documentation just my passport, I thought then that there was something not right. Glad I did not use them
Every year since getting the Retirement Visa, I submit the appropriate paper work, a letter from my bank, copies of my bank book showing that I have a minimum of Baht 800,000 in my account for at least 3 months before extension request. I never had to leave Thailand and come back in order to submit for an extension?
