My friend is currently in Thailand and is paralyzed, receiving ongoing treatment at a hospital. He originally entered Thailand on a tourist visa. At the moment, he has to extend his visa every 3 months under a medical visa extension.
Would he have any chance of changing his visa to a retirement visa or a DTV visa? (He previously received an 89-day overstay fine because he was hospitalized and unable to go to immigration to extend his visa at that time.)
