*shrugs* Shouldn't be making posts about other members of the forum in here then. That kind of thing can (and should) be challenged.

Mark, your guess is correct! I live in the LA area.
When the leaving date drew close for me, I was nervous too. I was nervous and extremely anxious...Visiting a country for a few weeks at a time is very different from picking up sticks and relocating...You become like a blank page...like a child...as you need to learn how everything works...Saying goodbye to the family and friends was 'pants.'
Anyway, don't worry...You will be fine! Many have 'gone before you and survived' the move... so will you.
Here are a few, 'before-you-leave-England' tips.
1.If you can, bring 2 written, employment reference letters (each from different employers)
2.If you haven't had an eye test lately, have one - the cost of an eye test here, without insurance, is around $125. Also, if you need glasses buy them in England. Again, the cost of specs here, without insurance is huge.
3.If you haven't had a dental check lately, have one...so if you need work carried out, do it before you arrive. The cost of dental care in the US, without insurance, is huge. To give you an example, I had a deep clean, with insurance, and it cost me $500 - that's my out of pocket cost after the insurance pay their part.
4.If your relatives, children or friends are worried...remind them you can use Skype on your home computer or iPhone to keep in regular face-to-face contact with them.
5.Persuade your 'better half', if you can, to get a LAN line. The Vontage telephone service is fab! For a low price, you use their free international call time...I call my mother everyday for as long, and as often, as I want. Also I tell my friends and family to call me and I'll return their calls so they don't take the burden of the cost.
6.Remember the K1 visa is a one-way-use permit. In other words, you can't return to England until you adjust your status ($1050) and obtain your green card. That can take between 4 to 12 months. So, don't count on being able to return home for a while...You can leave the US but they won't allow you to return. You'll have to start the visa process again. Not a K1 one visa, but a spousal visa.
7.Settle all your debts, if you can, before you arrive.
8.Tell the tax office (Inland Revenue) you are leaving so they know... Just in case you have to return to England, to resume residency. Not important, but a tidy way of doing things.
9.Bring a copy of your CV, they call it 'resume' here. Also have a copy on a flash drive or CD as a back up.
10. Bring your original copies of your qualifications, and some copies...just in case you need them.
11.If you can, get a copy of your medical history from your GP. They will expect a small charge for this.
Okay. That's all for now! Hope my tips help somewhat!

Exactly my point. Not everyone is ultra-prepared and a know-it-all. That's why there are forums - so people can ask questions and get answers!

Not helpful at all.
The guides (specifically the K-1 Visa Guide and K-1 Flowchart) will give you a hand here. Basically, your petition gets passed to the NVC (National Visa Center) - who will then, assuming all is well, mail it over to the London Embassy.
But before then, start ringing the NVC to see if you can get the case number and get the medical at Knightsbridge booked. You'll also need to sort out your ACPO certificate. Like I say, the guides have all the answers!
