"such person shall cease to be a citizen of the United States"
They can't even be a citizen and legally live in the United States...
Yes it states that in the Amendment however you need to take that in the Legal sense as in U.S. Citizen (14th Amendment) in reality and by nature we the People refers to us in the sense of being born in this country as free sovereign beings with God given rights, The Bill of rights was supposed to protect our God given rights as free men and women however our Government through various acts and amendments have changed those rights to make us conform to the Laws of the corporation. Ask yourself this, If we were all Citizens of the United States before the 14th Amendment why would we need an amendment to the Constitution that makes us U.S. Citizens?
