@JosioDiaz having read your original post, @rjs pertinent questions and comments and your repose thereto, I would like to add that
(A) US taxes persons based on (1) citizenship ( US citizens are taxed on world income no matter where they live or earn ); (2) all residents whom live on US soil ( world income again -- there are exceptions ); (3) Rest of the world (RoW) on US sourced/connected income. It is an extremely broad taxation reach.
(B) US also uses , probably because of domestic reasons, the principle of "income sourced to where work performed".
In your case ( assuming that you are currently not a resident for tax purposes ) because you are performing the work abroad ( for a US based entity which you do not significantly own/control ), the income is neither US sourced or US connected. Thus US should have no Tax interest.
What I find interesting is why the question? What is the reason behind this ? Please tell more about the situation-- please
Does this make sense?
