I am a dual German/South African citizen. I have worked on three continents in multiple countries. Neither South Africa nor Germany has withheld taxes from me when working in another country. When I was living and working in America for 11 years, neither South Africa nor Germany taxed me.

If you are an American, and you work in another country, you have to pay taxes to both the country you work in and American.

You are talking complete and utter fucking nonsense. Just for you to state that shows you how unformed you are.
