> what's bizarre to me is how strict Europe is with jus sanguinis Asian countries are also notoriously hard to get citizenship in. > Why are there zero barriers for a Greek or Estonian to live and work in Spain but tough immigration rules for the spawn of their 15+ latin american colonies, who speak the same language and have the same religion? Could be worth exploring for Spain and Portugal. There's a "transitive property" issue, however. It'd be hard to do this without, effectively, adding the former Spanish and Portuguese empires to the EU. This would also run into the Monroe Doctrine, if you carried it far enough. But it is an interesting idea.
