Hi! I have applied for schengen visa at the Italian consulate in japan to attend a onference in Rome, but it was refused by unfair reason " one or more member state consider you to be a threat to public policy, internal security or public health as defined in article 2(19),,,. while i submitted all required documents. I am from Afghanistan and studying in japan, please tell me does it affect my future applications? The conference is already finished, should I appeal against it or not.
