YES you can presuming nothing goes wrong with your medical it only takes 2 days or if you're done a day before your interview St. Lukes will let you hand carry your result to USEM during your interview.
As for my experience, I was ask to return after 12 days since there's sexual contact in between unsafe days and can't received shots, and i was also referred to personal evaluation because of my prescription meds which i didn't bring my cardio med. certificate during the physical exam that supports it.
If things doesn't goes smoothly on your medical you will be ask to cancel your interview and St. Luke's will be the one to reschedule it for you.
But, I didn't wait for st. luke's to schedule for me coz we're on a hurry so I re schedule myself online and was interviewed on July 30 WITHOUT vaccination. I was approved but got 221g for medical release. And because St. Luke's had typo error on my docs they have to wait for the doctor to sign in. They forward my medical on August 5 at the same time my status was changed to ISSUED. on 7th 2go picked up my visa and received in our province on Aug 8th.
Just shared my experience so you will have idea if there's some thing out of our control happened during the medical.

My interview will be next month, September 4, all of my VJ friends under IR/CR who already had their interview, advised me and others that ALL ORIG civil documents (NSO BC,MC) submitted during the NVC stage, MUST also be brought again to the interview plus a fresh copy of NBI clearance and Cemar/Advisory on Marriage.
If your wife is registered late in her BC, she also will be required to bring her baptismal cert.
For the divorce decree and police clearance from other countries, I am not sure if copies will do. The I-864 must have an original signature from the sponsor, copies of 2012 ITR and W2 with recent paystubs.
Proof of ongoing relationship and communication such as skype call logs, remittance receipts, photos etc..
I hope I did not forget anything.

Thanks for this thread made me wonder what's gonna be my first job when we arrive in US, I'm not picky though, most of my experience are on graphic designs but prefer to work not infront of a computer anymore ...

You only have to take your passport and passport photos. The rest will be there in your folder from the NVC. And take credit card to pay the courier. £14.50. And take interview letter to get in the door.
No additional copies needed at the embassy unless they make you feel more secure having them with you in your folder. It's pretty light for you. K1s and DCF filers take all that to the embassy because they don't do NVC processing.

wow! congrats! another reason for thanks giving!
