The "right of self determination" does not exist in the US constitution or law. It's a rhetorical slogan coined by Woodrow Wilson, and his idea of "self determination" came from growing up as a racist southerner who felt the South should have been allowed to self-determine a continuation of chattel slavery.

How this has anything to do with the immigrants in my city trying to live normal lives, perhaps you can explain.

Sorry, I don't think I follow this comment. Which part of kidnapping people is the kidnappee's self-determination?
