Bringing people out of low-productivity environments is good for everyone, even though there may be some transition struggles (probably the number one concern for people who favor restricting immigration). It is also most likely the thing that will fix "over there" because it will force change in places losing talent, as well as educate a bunch of people, many of whom will likely want to go fix their low-productivity hometowns and countries. Charter cities are another option, but the argument that "we need to fix over there so don't let people move" is just perpetuating the status quo more than anything.
