J & K

Similar to what victorian221b said. Your receipt number on your NOA1 will not show up in their system. The receipt number on your biometrics appointment notice is what is formally assigned to your case file. I would also compare it to your denial notice as it may be different. Check all reciept numbers with the USCIS website.
As long as you and your wife are legit then the worst thing that can happen is that you will have to file an appeal and appear in front of an immigration judge to explain your situation. The judge will almost assuredly rule in your favor. While the burracrats at the USCIS my not understand the unexpected events that happen to real people, the immigration judge most likely will.
For now get a competent immigration lawyer (be careful, there are lots of really bad lawyers) and put aside some money for your subsequent immigration and legal fees.
Good luck,

I noticed a couple of my fellow September 2010 K1 filers in here with September 12 Biometrics appointments. That happens to be our day as well. It will be exactly 364 days from when I sent in the K-1 petition.
Has anyone else had any troubles opening a joint bank account with their forigen spouses? I do not know if it the the laws in Florida or what, but no bank will accecpt her passport with visa and stamped I-94 card along with ss card and marriage certificate as suffucent ID. It is like they are refusing to aknowlage her existence.
The mingling of financial assets and joint ownership of property is one thing that the AOS adjudicators look at, so I was hoping to get some things set up soon. I guess we will have to wait for her EAD card so she can get a driver's license to use as ID.
