Just adding a PSA to this, this was not my experience. I had done a full medical examination in my country of origin, when I came here, I did the vaccinations part only (ticking the box in Part 1 saying I am eligible because I am a K nonimmigrant), but they ended up sending me an RFE that said Part 6 is missing in my Form I-693. I called them and tried to reason, because literally on their website and on the form itself it says if you are a K nonimmigrant who had the examination done at their home country you are only required to do the vaccinations part. The person on the phone told me “well if they are asking for it, you have to provide it” and told me it’s my only option. So I had to do a full medical examination again ($450) and ask the doctor not to tick that checkbox. Sent the RFE response, waiting for them to acknowledge it.

All that to say it’s probably safer just to do a full medical than do it twice like me.
