What persons are
NOT subject to the jurisdiction of the United States?
Diplomatic immunity is a status granted to diplomatic personnel that exempts them from the laws of a foreign jurisdiction.
The Vienna Convention of Diplomatic Relations (1961), which most states have ratified, offers diplomats acting as officials of state almost total protection from subjection to criminal, administrative, and civil laws belonging to the country in which the diplomatic mission is located. Diplomats assigned to missions located in foreign countries remain subject to the laws of their home countries. The diplomat's country of origin has prerogative over whether or not a host country may prosecute a diplomat under its (i.e. 'foreign') laws.
How far does this immunity extend?
22 U.S. Code § 254a - Definitions
(1) the term “members of a mission” means—
(A) the head of a mission and those members of a mission who are members of the diplomatic staff or who, pursuant to law, are granted equivalent privileges and immunities,
(B) members of the administrative and technical staff of a mission, and
(C) members of the service staff of a mission,
as such terms are defined in Article 1 of the Vienna Convention;
(2) the term “family” means—
(A) the members of the family of a member of a mission described in paragraph (1)(A) who form part of his or her household if they are not nationals of the United States, and
(B) the members of the family of a member of a mission described in paragraph (1)(B) who form part of his or her household if they are not nationals or permanent residents of the United States,
within the meaning of Article 37 of the Vienna Convention;
(3) the term “mission” includes missions within the meaning of the Vienna Convention and any missions representing foreign governments, individually or collectively, which are extended the same privileges and immunities, pursuant to law, as are enjoyed by missions under the Vienna Convention; and
(4) the term “Vienna Convention” means the Vienna Convention on Diplomatic Relations of April 18, 1961 (T.I.A.S. numbered 7502; 23 U.S.T. 3227), entered into force with respect to the United States on December 13, 1972.
Illegal aliens are not given any manner of immunity from U.S. laws, and as such and as defined by § 515.329(b) and § 515.330(2) they are persons "within the United States" so they are subject to the jurisdiction of the United States.
So, persons who do not have diplomatic immunity under the Vienna Convention of Diplomatic Relations (1961) and 22 U.S. Code § 254a can be arrested, charged with crimes, tried and sentenced. Illegal aliens in the United States can be arrested, charged with crimes, tried and sentenced, so their children that are born in the United States (requirement #1 in Section 1 of the XIV Amendment) and just like his or her parents being subject to the jurisdiction thereof (requirement #2 in Section 1 of the XIV Amendment), are citizens.
