Well Bosnia sounds like the place to be thenWhen your visa expires in Banja Luka, please tell me you won't urgently run to Montenegro.
Just find some nice, smart public dude to bribe, and stay. I mean, if you can't find a Public Parasite, sorry, Servant, to bribe in Bosnia Herzegovina, it'd be cause to despair with mankind.
You wouldn't even have to look that hard, I guess. Not only is it the Balkans, but, it's Bosnia, a bandit State. And within Bosnia, it's an almost separatist entity. I'm quite confident you'd find the right Public Servant.
