Similar to the previous poster, after following the instructions for writing name etc on the back of the photos, I put them in a ziplock bag and taped the bag to a blank sheet of paper. I did this for each of the three forms.
No RFE, no interview, just approval.

The US Embassy reports to the DOS, their computers are networked - one data base.
They'll ask for the LND number, when they get that, they can see everything and answer any questions you have. They've been pleasant and helpful when I've called.
BTW - you can get a good idea of what your dates are likely to be from the VJ timelines: this link
Not everyone keeps them updated but there's enough to give some idea .. as long as there's no complications ... good luck.
My thought on your target date in August is that you might need to delay entry to the US because the visa requires marriage in 90 days or less. Watch for that.

London Medical – Knightsbridge Doctors – Bentinck Mansions
I had my medical at Bentinck Mansions on 2nd March 2011.
I am writing this to highlight points that I haven’t seen written about on visajourney already. Nich-Nick’s Tips for K1’s was particularly helpful. The other reports had given me an excellent appreciation of what was going to happen at the medical. I read many of them. Thanks to all who contributed. It helped to make me feel confident and to be un-phased by all that was asked of me on the day. Let’s face it scrubbing around in partial undress can be distracting.
The letter requesting the medical was only received a week after my medical. It was only with insight from VisaJourney.com and the dogged persistence of my fiancé to phone the DOS to illicit the information that I had an LND number, then that the Embassy had received the petition and then the Embassy ($16 call) that we could make the medical appointment with the Doctors. The delay of the letter would have extended my visa journey by 2 weeks if he hadn’t been so pro-active.
At the same time he paid for the interview (in advance). They e-mailed confirmation of the intention to interview but not the date. This may have raised my profile within the organization because a further DOS call by my fiancé started with the words “Fiona has….” They knew my name.
In advance of the medical I had been to the GP to get some of the vaccinations and had requested my medical notes. The GP nurse and administrative staff were sent into a spin by my requests and I had to nudge them gently into compliance. Printing off the Embassy page Interview Preparation to talk through with them helped with that dialogue and sheer smiling persistence won through. I recommend approaching the GP months ahead of the medical time scale. Some of the vaccinations come in 2 parts given across 2 to 3 months some even longer. I had an MMR injection. Part 1 and part 2 had to be a month apart. It’s worth checking sooner rather than later.
My appointment was at 8.50 a.m. I was there well in advance (just in case the London Transport System was struggling that morning) I was travelling from Hertford. I went for a coffee after I’d located where the Mansions were. I arrived at the Doctors 10 minutes before the appointment. This gave time for me to fill in another questionnaire and use the bathroom! The waiting room had 5 other people already waiting. I anticipated a long morning. Not so. I was one of the first to be seen. They have a system where your appointment time is on a lollypop stick tucked into your file. They seemed to be following a booking plan. Take something to read or do.
I was first taken to a room to be x-rayed by a quiet professional nurse. She seemed mindful of privacy and dignity when getting changed and being x-rayed. She also gave clear advice about what to do next.
Then, I saw the nurse who wanted to talk about my vaccinations. Varicella came up. I’ve had chicken pox so that dispensed the need for the varicella, she said. I needed one other injection. She offered that I get it done with my local GP and fax the proof back to her. That would have delayed the notes going to the Embassy. I opted to get it done at the medical. She was skilled and quick and it was over in a very short time.
On my form she ticked a box that said that my immunization was incomplete (No varicella) then wrote, in medical code, in a table that I had had chicken pox. The nurse was at pains to tell me that this would not affect my interview and visa. We are currently wondering how the “Incomplete” nature of my records will affect me when it comes to applying for my change of status.
Then I saw the Doctor. The one that many had experienced brusqueness from that one doesn’t want to experience whilst in a house coat on a medical table. She was clear with me about what she was doing and why. Equally clear about what I might do to improve my general health. She was pleased I had a limited amount of caffeine. She explained the ills of alcohol on the body.
The advice of someone who said, ‘she’s not going to be a friend, she’s doing a job’ helped me. Towards the end of the interview she then chatted and became quite personable.
I sensed that her job must be very repetitive and possibly, at times, be undemanding of her capabilities. She became interested and more thoughtful when I became more interesting to her.
Then it was over. I was out by 10. 00a.m.: Lighter of wallet by 225 pounds and lighter of spirit.
I was told by the receptionist that my medical records would be at the Embassy in 4 working days and that they’d then call me for interview. I now have an interview on the 24th March. 22 days after my medical.
I wish all the best, to those of you awaiting your medical. I hope what I have written gives another useful insight into the process.
A thought came to me during the medical that the experience at the medical will be something that I very quickly forget when the visa arrives and my life can start again with the person I love.
