Considering the history of the constitutional provision, the clause's apparent intent, the English common law expressly applicable in the American colonies and in all of the original states, the common use and meaning of the phrase "natural born" subject in England and the American colonies in the 1700s, and the subsequent action of the first Congress in enacting the Naturalization Act of 1790 (expressly defining the term "natural born citizen" to include those born abroad to U.S. citizens), it appears that the most logical inferences would indicate that the phrase "natural born Citizen" would mean a person who is entitled to U.S. citizenship "by birth" or "at birth." Such interpretation, as evidenced by over a century of American case law, would include as natural born citizens those born in the United States and subject to its jurisdiction regardless of the citizenship status of one's parents, or those born abroad of one or more parents who are U.S. citizens (as recognized by statute), as opposed to a person who is not a citizen by birth and is thus an "alien" required to go through the legal process of naturalization to become U.S. Citizen.
