During the process of developing a new U.S. Constitution Alexander Hamilton submitted a suggested draft for a Constitution on June 18, 1787. He also submitted to the framers a proposal for the qualification requirements in Article II as to the necessary Citizenship status for the office of President and Commander in Chief of the Military.
Alexander Hamiltons suggested presidential eligibility clause:
"No person shall be eligible to the office of President of the United States unless he be now a Citizen of one of the States, or hereafter be born a Citizen of the United States."
John Jay wrote in a letter to George Washington dated 25 Jul 1787:
"Permit me to hint, whether it would be wise and seasonable to provide a strong check to the admission of Foreigners into the administration of our national Government; and to declare expressly that the Commander in Chief of the American army shall not be given to nor devolve on, any but a natural born Citizen. "
Article II, Section 1, Clause 5 of U.S. Constitution as adopted 17 Sep 1787:
"No Person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any person be eligible to that Office who shall not have attained to the Age of thirty five Years, and been fourteen Years a Resident within the United States."
And they also set up no formal process to verify natural-born citizenship. What’s your point?
(page 246)
And the constitution itself contains a direct recognition of the subsisting common law principle, in the section which defines the qualification of the President. “No person except a natural born citizen, or a citizen of the United States at the time of the adoption of this constitution, shall be eligible to the office of President,” &c. The only standard which then existed, of a natural born citizen, was the rule of the common law, and no different standard has been adopted since. Suppose a person should be elected President who was native born, but of alien parents, could there be any reasonable doubt that he was eligible under the constitution? I think not.
(pg 250)
6. Upon principle, therefore, I can entertain no doubt, but that by the law of the United States, every person born within the dominions and allegiance of the United States, whatever were the situation of his parents, is a natural born citizen.
