We also got documentarily qualified today. We submitted the AOS and civil documents on April 18, only took 10 days for approval!
I have one concern though, the email from the NVC says not to give up employment until you have received your visa. I assume this is only to ensure you have enough earnings to meet the threshold for the AOS? My wife is over the threshold without my income, I did not even submit any income information, so I assume it's fine for me to submit my resignation?
