He's saying he thinks USCIS has made a mistake and labelled your file as one that is adjusting their status instead of one that is petitioning for a visa. So therefore your case got sent to NRC instead of NVC. So you need to call USCIS and get transferred to an ISO (not the first person who answers the phone) and get this straightened out.
Read carefully and you'll get all the information you need.

It's true! Products have to meet certain standards in the states that are non existent in the middle east!
Have fun on your trips ladies! And regarding luggage/weight, always take out your clothes, you'll be buying a lot there so you won't wear half of what you're packing. Never toiletries though, you won't find anything that is as good there! Trust me!

No, 2012 tax returns and W2s will not be required until after the deadline of April 2013, at which time hopefully your husband will be physically with you in the states!

I might be coming late to the party but trust me, you do not want to move to the Middle East. I was born and raised in the states, got married in Qatar and have been living here for the last 7 years. I've hated every minute of it. I'm not saying to take my experience as law, not saying you're going to have the same experience, but I don't know of one person who made the move from the USA to the Middle East and liked it. They all pine for the day that they'll move back. And a lot of them are in different stages in their lives. Everyone from the married woman to the single party boy all want to move back after one year, most times less. And these are people who live in the Gulf, where there is no unrest, you're safe, and you have all the amenities and most of the technology of home. But you're still not home and there are HUGE differences that most simply can not adapt to. Human rights issues and etc.
I am SO glad that we're moving back, and you know the deal breaker? My son's schooling. He's 5 years old, will be starting first grade next year, and there is no way we'll be able to afford good schooling for him. So we're moving. Even if my husband (the non-US citizen) does not find the best job in the beginning it will still be better than living here. Not to mention I do NOT want to raise my child in this society, it's not Muslim no matter what anyone tries to tell you. You have a better chance of raising a well rounded and stable child in the USA.
This is all my opinion and I do apologize if I offended anyone, but this is my experience and what I've seen and learned during my expat years, and what I've seen and learned of others' expat experiences.

You should be calling NVC, NOT USCIS. And yes, call them every day, 20 days can be normal but you should be getting an answer soon. If you don't get an answer soon yes, you should go ahead and send your birth certificate again.
Don't book the medical yet b/c after you get your case complete from NVC you still have to wait to be scheduled an interview at the consulate and the interview will probably be scheduled a month after they tell you. For example, they send you a notification on Dec 10 that your interview will take place on Jan 13. You can look at the timelines to get a better idea of how long it takes to get an interview b/c it varies for every consulate.

Wait, you're in the UK, why didn't you file directly with the embassy? http://www.uscis.gov/portal/site/uscis/menuitem.5af9bb95919f35e66f614176543f6d1a/?vgnextoid=36dc6c0fe7f5d010VgnVCM10000048f3d6a1RCRD&vgnextchannel=1ac900c262197210VgnVCM100000082ca60aRCRD
It will go a LOT faster if you did it that way. I'm not sure if you can still do it that way, I'd contact the embassy to see if you still have that option.
Also, if you're both living overseas, you should have sent it to the Chicago lock box, NOT to Texas. That might be why they re-routed to Vermont. If your file is going to stay in Vermont you're looking at around 6 months just for approval from USCIS, then you're still going to have to go through NVC and all the other steps.
You probably won't make the June deadline if you're at Vermont, but if you've been routed to NBC you probably will. I'd call and talk to a tier 2 person, they'll be able to tell you exactly where your file is, then you'll be able to get a better idea about your timeline.

I'm sure you'll get a lot more help if you'll please take of the CAPS LOCK.

The K3 was made years ago b/c the CR1 was taking years to process so people would apply for the K3 in order to have their loved one enter the country while the CR1 was still being processed. Now, CR1 are not taking as long and so the K3 has become obsolete. There is no reason to file the K3 unless you just want to waste your time and risk your case taking longer to process.
DCF means Direct Consular Filing, it means that you will be able to file your papers with the USCIS office in your country and it takes a LOT less time than if you're one of us and have to file in states From what I've seen it might take you all together about 3 months (depending on the consulate of course) while the rest of us toil for minimum 6. And that's if we use all the NVC shortcuts and stay one step ahead of the process to make sure that whatever might be required is provided!
You'll be able to wait together no matter what route you take, as long as you can satisfy the domicile requirement (or intent to re-establish domicile) when it comes time to file the affidavit of support. But that's later, after you get your I-130 approval.
So again, your fastest course would be to get married and file with your consulate. It will be faster and it will be better for the non-us citizen when they arrive in the states since they'll immediately have their green card on arrival and be able to work and everything. Contact your embassy for more details as I don't think you'll be able to get more from here
Good Luck!
