Article II, Section 1 sets three presidential qualifications: natural-born citizen, at least 35 years old, and 14 years U.S. residency. The Framers required natural-born citizenship to ensure the President''s loyalty lies with the United States and prevent "ambitious foreigners" from seeking office. While the Constitution never defines "natural-born citizen" and the Supreme Court hasn''t ruled precisely on its meaning, it likely includes children of U.S. citizens born overseas, not just those born on U.S. soil. The 35-year age threshold reflects the Framers'' belief that executive duties require "solid wisdom and experience," as Justice Joseph Story wrote. The 14-year residency requirement doesn''t mandate continuous presence—it establishes "permanent domicil" so voters can fully know candidates. These qualifications cannot be altered by statute, only constitutional amendment. They''ve remained unchanged since 1787, making them among the Constitution''s most enduring provisions.
