Bulgarian Citizenship

hi there!

I am an Albanian and Bulgarian by heritage. I have applied for an Bulgarian Citizenship and also I have undergone all the process of interviews and all of that, now that I'm checking the processing of the file online it shows this: "По преписката Ви предстои да бъде извършен финален експертен преглед преди да бъде разгледана от Съвета по гражданство." Which means "Your file is about to undergo a final expert examination before being examined by the Citizenship Council." I wanted to ask how long is this step gonna take until I'm able to go and apply for a passport.

Looking forward to a reply,
Kind regards.
