Basically this is the document for "refugees" (95 percent of whom are really backdoor economic migrants), "asylees" (illegal alien with usually fake or embellished persecution stories), and green card holders on extended trips back home (usually folks who don't live in the USA any longer, or ever, but want to keep green-card status so they can come and go and petition for more alien relatives)
In other words, the document we give away like candy to all the wrong people...now has some more "security features".
