“the children of citizens of the United States that may be born beyond Sea, or out of the limits of the United States, shall be considered as natural born Citizens”.
The phrase “shall be considered as natural born Citizens” is a term of art which clearly states such children are being naturalized at birth to acquire rights which are comparable in most respects as those of actual natural born Citizens. The fact that these children born abroad were subject to residency requirements which were not applicable to natural born citizens clearly indicates such children born abroad were not natural born citizens.
There was no residency requirement for children born overseas in the Naturalization Act of 1790. The requirements to be considered a natural born citizen, if born overseas, were having citizen parents and a FATHER who had been a resident in the United States.
There is also a residence requirement of 14 years in order to be president.
