St. George Tucker, the editor, says this in a footnote:
Persons naturalized according to these acts, are entitled to all the rights of natural born citizens, except, first, that they cannot be elected as representatives in congress until seven years, thereafter. Secondly, nor can they be elected senators of the United States, until nine years thereafter. Thirdly, they are forever incapable of being chosen to the office of president of the United States.

Art. 1, 2.The work from which that is quoted was THE law book in every school of law in the United States for a VERY long time and is still in very wide use to this very day!
