I was told to go home last week. Well, they gave me the stamp for exactly one month from that date, but not the 60 days extension.
Unfortunately I don't know the exact details of their reasoning. Background story below in case that might be relevant in some way.
I arrived at the end of December on a normal Tourist visa. I've stayed in Si Racha all this time, and went to their immigration office first.
They told me to go home earlier this year already, but then I went to the Pattaya immigration office where I got the extensions without any questions.. until now.
(I know one other case of someone who was staying here who had to leave in april because she did not get the extension here, and did not try at another office).
So last week I went again to Pattaya for another extension, and this time they told me they will not do it anymore, I had to do it in Si Racha where I stay. And in Si Racha they told me that they will not give me the extension.
Since I am very grateful to be able to stay here that long (to be with my girlfriend), and was planning to go back anyway before the end of the year, I did not ask more questions and don't know how that decision is made. They did ask my girlfriend if we are married and why not, so maybe their decision is based on that as well.....
