I am sure, you will get your AP before you leave. My AP is approved on 02/04/04 and I got it 02/06/04. I don't know if the location matters. I live in Boston Metro area.
As you said, your AP is already approved, I think you should be ok, if somebody mails you the AP as it is approved before you left the country. Who knows that you got the Approval Notice in hand before you left or not. Mostly they are sending 3 copies of AP. If unfortunately you are not getting it before you leave (which should not happen), tell the person who is sending your AP to send it by kind of FedEx or UPS International to 2 different addresses (in your reach) so that in worst case you can get at least once. Just my thought.
Hope this helps.
