I have a problem with my passport, the booklet of pages was separated from the cover, i took my passport to authorities they only did scotch tape... so i traveled three times with that passport (Europe) but scotch tape started to coming off, so i went again to authorities they take off old scotch tape and replace it with another one, the problem is that when they took off the first one, they took off little of cover paper with it.
In my country it is not a problem(third world :( ). and also i can't replace it because (2014 passport) and with USA non used valid visa.
But I am going to go to Russia after one month and i found on internet that Russian customs are very strict in this matters, so please can anyone give me an advice if this passport are still valid for such trip??
