The very first Congress naturalized the foreign-born children of citizens.
The foreign-born children of citizens have always required naturalization.
You can believe what you like. Even if it's wrong, but I only tried to make the case that you are.
To sum it up one more time, this is the 20th century view and current understanding.
Status as a natural-born citizen of the United States is one of the eligibility requirements established in the United States Constitution for election to the office of President or Vice President. This requirement was intended to protect the nation from foreign influence.[1]
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 and legal scholars, together with relevant case law, is that natural-born citizens include, subject to exceptions, those born in the United States, and perhaps those born elsewhere if they meet the legal requirements for U.S. citizenship "at birth".[2]
The natural-born-citizen clause has been mentioned in passing in several decisions of the United States Supreme Court, and by some lower courts that have addressed eligibility challenges, but the Supreme Court has never directly addressed the question of a specific presidential or vice-presidential candidate's eligibility as a natural-born citizen.
Many eligibility lawsuits from the 2008 and 2012 election cycles were dismissed in lower courts due to the challengers' difficulty in showing that they had standing to raise legal objections. Additionally, some experts have suggested that the precise meaning of the natural-born-citizen clause may never be decided by the courts because, in the end, presidential eligibility may be determined to be a non-justiciable political question that can be decided only by Congress rather than by the judicial branch of government.[3][4]
