what amendment allows an individual to become an american citizen
Fourteenth Amendment to the United States Constitution The Citizenship Clause overruled the Supreme Court's Dred Scott decision that black people were not citizens and could not become citizens, nor enjoy the benefits of citizenship.[37][38] Some members of Congress voted for the Fourteenth Amendment in order to eliminate doubts about the constitutionality of the Civil Rights Act of 1866,[39] or to ensure that no subsequent Congress could later repeal or alter the main provisions of that Act.[40] The Civil Rights Act of 1866 had granted citizenship to all persons born in the United States if they were not subject to a foreign power, and this clause of the Fourteenth Amendment constitutionalized this rule.
United States presidential eligibility legislation No person except a natural born Citizen, or a Citizen of the United States, at the time of the Adoption of this Constitution, shall be eligible to the Office of President; neither shall any person be eligible to that Office who shall not have attained to the Age of thirty-five Years, and been fourteen Years a Resident within the United States.[1]
