I originally applied to sit for the exam in November 2008. When I got back from a few days visiting my parent's over christmas, I had an 8.5 x 11 envelope in my mailbox from the Department of State. Much to my surprise the envelope contained a PE wall certificate with my name on it. It turns out the DOS made a mistake in processing my application and the certificate was mailed prior to them correcting it. Now that I passed the exam, they issued me the same number that is on the wall certificate but I still haven't received my license. It's been 13 days since the license was issued.
