One hour after I applied for this program on-line, I was approved via on-line message. My message read:

"Dear Diplomatico:

We are please to inform you that your U.S. Customs and Border Protection, Global Entry program membership has been approved. You can begin using the program immediately.

Please visit globalentry.gov......"

(Full disclosure: I already have a SENTRI card so that may have expedited the approval process.)

Still, that's impressive. ^
