, this is strange, as I get all US embassy press releases, and in country news, and this was not one of them. The last announcement I received concerning visa extension was July 29th, and just informs of the amnesty extension until Sept 26. They do call it the automatic visa extension, with no amnesty wording. I think someone has misinformed people. The current notice I have received is only about the literacy program the US embassy is contributing to in Thailand. Nothing in reference to that supposed letter from the embassy, from the 25th. Anything like this to make it official would have to be published in the Royal Gazette, and in ten years of working with the embassy, I have never known them to pass on "verbal" communications with any government ministry.
