§ 217. Children born in the armies of the state.
For the same reasons also, children born out of the country, in the armies of the state, or in the house of its minister at a foreign court, are reputed born in the country; for a citizen who is absent with his family, on the service of the state, but still dependent on it, and subject to its jurisdiction, cannot be considered as having quitted its territory.
That Congress attempted, wrongly, to legislate natural born citizenship to children of citizens born abroad in 1790 says to me that the matter was not regarded as being quite so clear cut, patlin.
Doubts remain. Those doubts are evidenced by the various Bills sponsored in an attempt at amending the Constitutional natural born citizenship requirement to encompass children born abroad to parents in service to the military.
