Thanks, I think in some of the answers it was mentioned that there was no need to use the resourced-by treaty, and that de-railed the original question about the additional form that you have now answered.
So, resourced by treaty is needed in order to mark the US sourced income as foreign, and we specify in that same 1116 form the taxes paid in the foreign country for that income. (Credit will be limited to the amount that US would tax).
Form 8833 is not needed in these cases for individuals.
