I should say its easier in the EU because most of the information has been digitalised. Less documentation is needed. For example the police report is sent directly to the embassy, the pasport is e-passport or even biological passport etc. so the information is very consistent and I guess its easier for the embassy to cross-check.
Whatever be the case one has to be very prepared and just be yourself.
I don't know the questions they ask but I dont think they are special for EU...They are mostly the generic questions you already know: whats your name, da´te and place of birth etc....
Thanks a lot. I am now happy because I have passed this nigeria of a thing when I was travling outside niger in 2002/ THANKS may Almighty God grant us our success.
