And with which way? BusCroatia offered me to go from Croatia(dubrovnik). But I'm citizen of Azerbaijan and I need visa for Croatia. So I need to pass the border from Montenegro to Bosnia and Hersegovina. and I have flight from Tirana at 18 august. So I have to go Banja Luka and have to be in Tirana at 18 august. I will leave Tirana at 13 august. Is it applicable to go Banja Luka and Back in 4 days?
