Let me cite international law, then US law.

The 1966 International Covenant on Civil and Political Rights has been signed and ratified by 173 countries, including the US. It recognizes that the “inherent dignity and the equal and inalienable rights of all members of the human family [are] the foundation of freedom, justice and peace in the world.” It then specifies the rights of all peoples:

“All peoples have the right of self-determination. By virtue of that right they freely determine their political status and freely pursue their economic, social and cultural development.”

“In no case may a people be deprived of its own means of subsistence.”

“any person whose rights or freedoms as herein recognized are violated shall have an effective remedy, notwithstanding that the violation has been committed by persons acting in an official capacity”

“Everyone lawfully within the territory of a State shall, within that territory, have the right to liberty of movement and freedom to choose his residence.”
