"If aliens might be admitted indiscriminately to enjoy all the rights of citizens at the will of a single state, the Union might itself be endangered by an influx of foreigners, hostile to its institutions, ignorant of its powers, and incapable of a due estimate of its privileges."
Joseph Story, Commentaries on the Constitution, Book 3, §1098 (1833); Philip B. Kurland and Ralph Lerner, eds., The Founders’ Constitution, Volume Two: Preamble through Article I, Section 8, Clause 4 (Indianapolis: Liberty Fund, 2000), 619.
