Proof of Work require no secret information as an input and have to be easy to verify. But most importantly, why would anyone do this?

Passport issuer can act like certification authority, this is not a trustless system where PoW can be used for something. Public key infrastructure is a solved thing with it's own problems, but verification is not one of them if authority is working as it should.

EDIT: Let's not even mention that smartcards have effective lifetime and efficiency.
