Yesterday I passed through Don Mueng airport and was approached by a wandering 3 man team from immigration as I sat in departures . They were incredibly helpful and spoke excellent English. I am currently on an extension of stay as married to a Thai . The last extension ended on the 27 th May . Previously I went to Khon Khon immigration to get a further 60 day extension but was informed I would be covered by the current amnesty. Today the senior immigration officer within the team informed me that I could simply apply again for the same 60 day extension any time up to the 31 st July . Appreciate there maybe a variance in the information other people are getting but this was solely what I was told as of yesterday evening.
