I live in Nakhon Sawan and they have an excellent office however they do rigidly stick to the rules. If applying for an extension they gave me until the passport expired.
as they own a large chunk of dollar debt don't rule anything out. The Fed can only print so much monopoly money before the bubble bursts. The British pound was once the world's reserve currency until their empire crumbled.
Enjoy it while it lasts. Many countries around the world ditching the Petro dollar and I believe it's days as the world's reserve currency are numbered.
