I got the same today at Phuket immigration, told to go back oct 12 but with the amnesty I was ok until oct 26, the io made a point that I had to go back on the 12th
I called Phuket immigration yesterday morning as couldn't get in and my under consideration stamp expired on 22nd, the very helpful guy (who has been assisting me with damaged passport but that's another story) told me I was covered until April 30 and wait for announcement coming and that I would be covered for whatever duration that was
Same situation, one year multiple entry non b, visa run due April 7 and for good measures my dog ate my passport last week so can't do any last minute dashes anywhere whilst waiting for new passport to arrive!!
firstly I had the 3 month single then 1 year multiple complete with border runs, now this is coming to an end I've been told at local immigration by the volunteers there that I can get extension of stays based on employment valid for 3 months and all I need to do is keep going back to immigration for further extensions etc... that's what I was asking plus the medical thing
