@overcurious ,
(a) looking at the instructions for line seven -- what it is distinguishing is between US citizens of two types -- (a) US citizen as those who are domiciled in US and became a citizen by birth in the US or by residing in the US and gaining citizenship OR (b) those whom are not domiciled in US territories ( like Guam etc. ) and US citizen because of being born and or residing in US territories. For purposes of Fomr 709 the former is US citizen while the latter is Non-Resident and Non-citizen.
(b) You as a resident ( Green Card / Resident for Tax purposes ) show your own citizenship ( that your passport shows ) on line 7
Does this make sense ?
Is there more I can do for you ?
