They’re the Oglala Sioux my dude they’re only in the USA stop trying to stretch this shit. All three of these people are US citizens. To quote their president “The Oglala Sioux Tribe’s memorandum makes clear that ‘tribal citizens are not aliens’ and are ‘categorically outside immigration jurisdiction. Enrolled tribal members are citizens of the United States by statute and citizens of the Oglala Sioux Nation by treaty.”
Modern archaeologists and historians now support the hypothesis that indigenous peoples reached the America via boats traveling along the pacific coast, and current archeology indicates this migration slightly predates the formation of the beringian land bridge. This is pedantic but is intended to show that I am well aware of the migration history. They are the least immigrant out of anyone because they got here first out of all modern people groups in the Americas.
