No, the U.S. Constitution does not exclusively protect citizens. Many of its core protections, including due process and equal protection under the 14th Amendment, apply to all "persons" within U.S. jurisdiction, regardless of citizenship, immigration status, or legal presence. Non-citizens, including undocumented individuals, possess key rights such as protection against unreasonable search and seizure and fair trial rights.
Key details regarding the scope of Constitutional protections:
*"Person" vs. "Citizen": The 5th and 14th Amendments use the term "person," which the Supreme Court has interpreted to include non-citizens, including foreign nationals and those in the country unlawfully
*Fundamental Rights: All people in the U.S. are entitled to core rights, such as freedom of speech, religion, and the right to remain silent.
*Legal Protections: Non-citizens are entitled to due process, meaning they cannot be deprived of life, liberty, or property without legal proceedings.
*Criminal Justice: Non-citizens are protected by the 4th, 5th, and 6th Amendments in criminal matters, including the right to a fair trial, counsel, and protection against illegal searches.
While some rights, such as voting in federal elections, are reserved for citizens, the fundamental protections in the Constitution are not exclusively for them.
