Back then, DHS was involved in the background check process, and it was apparently more than just a national agency check, though nowhere near like a national security background check, where they put people in the field, interviewing employers, past/present clergy, teachers, even the husband and wife that ran the very small country grocery store, where I grew up, as a kid. No. 1 on the birth certificate file, is that proof of citizenship. I figure, since the birth certificate itself had changed to a newer supposedly more secure form and design, including new features, it became their policy to only accept the newest computerized version. If you are wondering what that looks like, think of the picture of Obama's birth certificate, published back when that idiot trump tried saying he was from Kenya. I have dealt with at least three of the US alphabet soup agencies, in this country and while stationed in Europe, and the difference is daylight and dark. They know literally everything about you, just to act in reliance, where at least two have been the worst type of casual, intentional liars, just as part of trained trade craft. DHS (new kids on the block) looks like the nice guys by comparison, or did until this administration. Now, I don't know.
