I come with good news for you all, and a bit of bad news for myself. Just minutes ago I got an email from NVC and I thought I was DQd and got so excited. Then I checked the website and I had an RFE.
The reason was that my wife's brother-in-law was not qualified as a household member, and we were asked to add him as a separate joint sponsor. This is pretty odd, because we had uploaded their marriage certificate and everything. I know this sucks, but I'm sure won't happen to you guys and wish all of you hear good news soon.
