Long story and I did not need it but I was young and ignorant and got it done for no charge, maybe look for Civil Surgeons who serve the Hispanic community.
So in your case you had your K1 medical and did not have a complete vaccination done and elected to complete them in the US.
Generally this is a mistake, there can obviously be situations where this arises and it is what it is but they are pretty rare.
So being in that situation you have the main issue, CS's who will not do only the I 693 and only a few it seems will. Plus of course you need someone local. Then you need that they will do it and how much they charge.
As far as a list sadly not really practical.
Civil Surgeons come and go
Their charging structure and practices change
This is a rare situation and as I mentioned best avoided
VJ simply does not have enough members, people in this situation, for such a database.
Really only USCIS could do this, incorporate it in their database.
