Your reply has totally got nothing to do with the first question
you posted.
I'm saying its not feasible becuz when you are a PR in a country,
your PR status can be revoked for reasons based on their
immigration law system. now if you were to drop your spore
citizenship just to withdraw your cpf and is just a PR in another
country but somehow your PR status got revoked due to changes in
their policy.. where does that leave you? a QUALIFIED UN
REFUGEE?
Its my assumption that a person who drops his cert can
be still allowed to live in the world even if he is no citizen of
any country.
sure you can of course live in this world... but where is the
question? being 'citizenless', what makes you think you are able to
travel freely around the globe?? Its the opposite actually..
