If you are an American with the dtv and you 1) Stay in Thailand the first 6 months , and then 2) Travel to Korea for 1 week, and then 3) Come back to Thailand for the last 6 months, do you need to file special paperwork for taxes in US? Or do you just pay US taxes as per usual ?

For those on the DTV wanting a tax ID, I went into the office in my district today with google translate in hand (no one speaks English in any revenue office) they were extremely nice I had my Tax ID in 5 minutes. I had filled out the form in advance and used google to translate it, and my girlfriend was on standby to talk to one of the reps in case things didn't go well. They couldn't have gone better. I already had "need tax ID don't speak Thai" translated on my phone when I walked in. The guard and rep who got my ID was very interested in English, how I used Google Translate and the United States.

So what happens if you stay past 6 months ? Am I forced to pay taxes in thailand?
