Ok Guys, this will come to us all so please read.
Those of us, long term residents of Thailand, who see Thailand as “home’ will, if we survive, reach an age of infirmity, be it physical or mental, where the annual trip to Immigration is impossible, as will the efforts of obtaining the necessary paperwork required to support the yearly extension. Question then, what is the solution? Is there a procedure in place to accommodate us, someone must have been there and done all this already, or is it all down to a Law firm or Thai family to take up the battle with immigration?
TLDR : Answer Summary
Long-term residents of Thailand facing health challenges may struggle to attend annual immigration appointments required for visa extensions. To address this, one solution involves appointing a power of attorney to a trusted individual or law firm who can handle immigration matters on behalf of the incapacitated applicant. Additionally, a letter from a registered doctor is necessary, confirming the individual's inability to attend in person due to medical reasons. This process is advised to prevent complications and ensure continued residency.
