How many years of citizenship must a person have to be eligible for the Executive Branch?

To be eligible for the Executive Branch of the United States government, specifically the office of the President, a person must have been a citizen of the United States for at least 14 years. This requirement is established in Article II, Section 1 of the U.S. Constitution. The rationale behind this requirement is to ensure that the candidate has a substantial connection and commitment to the country, having lived in it for a considerable duration before seeking the highest office. This provision helps to ensure that candidates are familiar with the nation's values, challenges, and the complexities of the American political system.

The other answer choices reflect durations that are not applicable according to the constitutional criteria, emphasizing the specificity and intent behind the 14-year requirement.
