Uncle sam wants YOU
Take proper advice, but here is my understanding:
There are only two countries in the world that pursue you wherever you live on the planet to file a tax return in your home country. Sadly, one is the USA and the other, I believe, is Australia.
This means you physically have to continue to file, but the if your local wage is equivalent to less than a certain threshold (Used to be $75,000...probably higher now) then you pay nothing on that amount. Anything above that is taxable in the US, the amount depending on how much you have paid in your new country. Guess what? You will have paid zilch in the UAE so Uncle Sam will have his hand out.
OK, now everyone can tell me I am wrong.
