Cornelius,
It has taken me around 4 weeks from the time i got the audit message to final approval from PMI.
A few LLs while getting your audit done by PMI;
1. Since i knew the previous managers well and had good relations with them for the past 10 years, they quickly approved and signed all the documents on the audit. So do keep good relations with your previous colleagues(managers), "You never know when they can bail you out of a situation like this

"
2. I got the audits documents signed and stamped from each of the managers. Though PMI doesn't expect you to sign each and every audit document, it's always a good idea to get them stamped. It is another level of validity provided by your previous employers. "It's good to be safe than get into another round of audits if PMI decides to do so".
3. Seal the audit pack properly and make sure that the documents are wraped in plastic covrs before you mail them, so that it takes care of the risk of getting wet and soiled.
4. I was in a situation wherein, a previous colleague quit the business i worked for and the business where i did the projects shut down almost 8 years ago. Do not panic in situations like these !!!! Just make sure that the person who is signing your audit documents is still on your friend list

... It's the person that matters not the organization....
I have set 2nd Sept as the date of my attempt at the PMP. Hope to clear it on my 1st attempt itself.
Will detail LLs once i'm done with the PMP
Cheers
