Has The System Changed?

[JackCassidyMusic 87]

Hi guys, I'm very confused about what's happening. I've looked at the K1 master thread but it's not clear (at least to me, sorry if it's obvious.)

I submitted my notification of readiness, as I have my medical booked and the affidavit of support is dude in 6-10 days, which is when my medical is, so should be here in plenty of time for the interview.
 

When I completed it, I was directed to this page which said this:

 

And when I opened that link, it invited me to register and pay for fees. The first list of options includes "I have received a letter from the consulate section with instructions register or schedule a K visa appointment." 
Can I do this now to book a time? Since my medical is on the 24th and I'll hopefully have all my documents from the USC, I can book a week or two after the medical, just in case anything comes up then. 
Or am I meant to wait for this letter from the embassy first (which I've heard a lot of people have never received.)

Thanks! <3

EDIT: I just tried to go through it to see what would happen, and turns out I'm already registered on the side. It's possibly leftover from the c1/d visa I had when I worked with an American cruiseliner. I take it I should just use this?

If it lets you book, and you're anxious to book,  then do so even if you are lying when you tick "I have received a letter from the consulate section with instructions register or schedule a K visa appointment."  Either follow their exact K1 instructions given on the London embassy website (and provided in your letter) or do it your own way. Do they even request readiness form from K1s anymore?

Xanex might help too. 😂
