This might be a bit late, and i hope you are already sorted out.
My wife and I had exactly the same situation. My wife is from Chicago
and I from London
.. we got married in the US. All you have to do is take your marriage certificate, along with proof of address in the Uk (from your husband) and a fee of (at the time $400), and then return later the same day for your visa. You get a 2 year probation visa and then go back to the embassy after 2 years for a permanent one.
Nice and simple!
