If you have to be naturalized you are not natural born.
@beastmode: Not exactly how it is worded. Also the term "natural Born" has not been defined within the legal system.
The U.S. Constitution uses but does not define the phrase "natural born Citizen", and various opinions have been offered over time regarding its precise meaning. The consensus of early 21st-century constitutional scholars, together with relevant case law, is that natural-born citizens include, subject to exceptions, those born in the United States. For those born elsewhere, there is an emerging consensus that they are also natural born citizens provided they meet the legal requirements for U.S. citizenship "at the moment of birth", but the matter remains unsettled. 4951
