What do you mean in 'officially legalized'? Its officially legalized everywhere where it is not forbidden by special norms from legislative body,and if in X country there are no general/special norms it means that its legal if it doesn't against general norms of criminal or private law.
So your question's answer is simple: Everywhere where is not general/special norms.In additional,I've heard that there are many countries which are against  bitcoin,but don't trust unconfirmed/untrusted sources/users because its just a speculative behaviour of people and from negative media.
