thanks a lot! My boss is willing to write a document stating that I am employed remotely, and can work indefintiely from Thailand, my position etc.. I guess that'll do it then.
One last question: I saw someone else post that they were required to show the 500k had been on a bank account for 6 months, but saw others say 3 months. Do you know the answer? Does it differ from one embassy to another? If so, do you know if Vietnam will accept 3 months?
