I can't get it to fit on 8.5x11 without shrinking it. Otherwise, I'd cut off either the name of the issuing authority on top, or the seal of the registrar on the bottom. There just isn't 3 inches of dead space to cut off in a photocopy to get it to fit.

I'll bring both a top and bottom photocopy, and a photocopy with the certificate scanned and shrunken to fit. I'm sure I'm not the only one with this issue, since all of the birth certificates issued by my city are the same size (at least they were at that time)
