GRCA-2002
Intereting theory...
Here is my case..
FP on Jan 23, 2003.. called FBI sometime during Feb 2003. FBI confirmed that the FP's were validated and sent to NSC on Jan 28, 2003 both for myself and my spouse...
Then called the support center on Aug 26, 2003 to submit CoA. Online status message changed to "On July 9, 2003 the results of the fingerprints review..... blah.. blah"
If you go by July 9, 2003 date... then the 15 month expiry comes on Oct 8, 2003 which is around 23 months from my RD... so it kind of works out... for me...
Cheers
