while I have never heard that happening, IF you do indeed meet the requirements to get the O-A from the thai consulate in L/A you'd meet them at any of the other 3 consulates that issue that type of visa as well (Chicago, Washington DC and New York).. I don't understand why you'd change plan and get a 6 month METV instead. Just post your application to one of the other consulates that issue O-A visas. They all accept applications by mail
