In the area of personal histories associated with their new identities and so on, anecdotally we've had some people say they are concerned that they haven't had enough input into their personal history. I assume this is done cooperatively and that you would ask them who they want to be, what they want to be.
How much work is done with the witnesses themselves to determine what their new identity is, their work history, and all that kind of stuff? I assume the witness is intimately involved.
