Again, the PP is REQUIRED by the CDC who governs their ability to continue to offer Panel Physician services to provide a personal copy.
You can easily show them that requirement from the CDC website via email.
They have to give you a copy. They can lose their license if you file a complaint.
You can get a copy JUST to see if it was complete and for peace of mind seeing that you ALREADY FILED AOS (????? No one knows still).
Also, you have not explained at which part of the process you are at NOW.
Your timeline says you don't even have a K1 visa yet but your post says different. Please fix your timeline so we can understand your situation and not have to ask.
If you already filed AOS and didn't submit a photocopy of your personal copy of the DS3025, you wait for approval, or interview and if they still don't have your DS3025 which is unlikely, then you redo your medical and get an I693 after the fact.
(DS3025s are only filled out abroad).
