"The bearer is abroad on a diplomatic assignment for the United States Government."
These are the words printed on a back page of my new black diplomatic passport. And even more "real" is the fact that it was returned to me via FedEx today with my Colombian visa affixed. No rubber stamp this; it's a very official-looking sticker that covers an entire page and has a forgery-foiling background pattern.
It even has a photo.
Ocupacion: "Funcionario"(Okay, I thought it should be "Funcionaria" but I'm not going to get all fussy now.)
Entidad: "Dpto. De Estado"
