How vital is police clearance paper for a DV interview? The rule is that I have to bring clearance from all countries I have lived for more than six months after the age of 16. In my case I will have to collect this from 5 five different countries. Can some one tell me if this is vital to my interview? I am a bit worried because some (two) of these countries are a bit inaccessible & I stayed there as part of a foreign mission to work on a project to which I have a letter from my employers whose headquarters are in Europe.
