Does anyone have experience of the Jomtien office? I am aged over 60 and have a non O visa (issued in London) for single entry 90 days but can only stay for 56 days as I need to go back to London for some appointments. If I deposit the 800,000 funds in advance of arrival, and so have the funds on deposit for the necessary 2 months, what chance is there that the Jomtien office would accept an early application for a retirement extension after only 45-50 days after arrival.
However, since I currently plan to spend only 3-5 months per year in Thailand and never spend more than 60 days per visit, I think it will probably be simpler just to return on visa exemptions or another O visa when needed.
