[a fool in paradise]

Baby has at least dual citizenship if not claims to even more nationalities.

There are Freepers who proclaim that even foreign born citizens can retain their previous citizenships and become naturalized US “dual citizens”.

This country is the global land without borders and anyone can claim to be of here, voting here and abroad and traveling on multiple passports.

Estados Stupidos.

This is all “new” interpretation of law and bunk.

They can. These US doesn't really enforce you actually revoking your old citizenships, and how can they? Sure, these US can revoke your citizenship if they determine that a naturalized citizen is still "keeping" their old citizenship, but that is very difficult to enforce. Not worth the time or effort unless it's an additional criminal case.

What if the other country doesn't recognize the revocation? Does that mean it's impossible for any of their citizens to ever gain US citizenship? Since obviously that means their people will always retain their foreign citizenship, so they could only become dual citizens.

What if tomorrow, Spain passed a law stating that all US citizens are now also citizens of Spain? Does that mean every US citizen loses their US citizenship, because these US doesn't allow for dual citizenship?
