State school for those living in Eastern Europe (10)

'those living in eastern europe' is the definition.
I can't judge whether this definition defines the answer.

'state school' is the wordplay.
I cannot quite see how this works, but
'state' could be 'bulgaria' (Bulgaria is an example) and 'bulgaria' is located in the answer.
'school' could be 's' and 's' is present in the answer.
A single letter 'n' remains which might be clued in a way I don't understand.
This may be the basis of clue (or it may be nonsense).

'for' is the link.

Can you help me to learn more?
