All persons born or naturalized in the United States, and subject to the
jurisdiction thereof, are citizens of the United States and of the State
wherein they reside.
No State shall make or enforce any law which shall abridge the privileges or
immunities of citizens of the United States; nor shall any State deprive any
person of life, liberty, or property, without due process of law; nor deny to
any person within its jurisdiction the equal protection of the laws.
根據美國第十四條憲法修正案第一款的規定
任何在美國出生的人都是美國公民
也因為這個規定，數不盡的人跑去美國生小孩
台灣有多少小孩有美國國籍啊，這個有辦法統計嗎？
