Google: "Who does the US Constitution apply to?"

Answer:

Here's a more detailed explanation:
"All Persons":
The Constitution's protections, particularly those found in the Due Process Clause and the Equal Protection Clause, apply to "all persons" within the jurisdiction of the United States, not just citizens.
Non-Citizens:
This means that non-citizens, including immigrants (both documented and undocumented), tourists, and visitors, are also entitled to the protections of the Constitution.
Due Process:
The Due Process Clause ensures that no person can be deprived of life, liberty, or property without due process of law.
Equal Protection:
The Equal Protection Clause ensures that no person within the jurisdiction of the United States can be denied equal protection of the laws.
Examples of Constitutional Protections:
First Amendment: Non-citizens are protected by the First Amendment, including freedom of speech, religion, and assembly.
Fourth Amendment: Non-citizens are protected from unreasonable searches and seizures.
Fifth Amendment: Non-citizens are protected from self-incrimination and double jeopardy.
