I am not sure about a new law like that, and it won't usually affect things retroactively, otherwise everybody here who received their green card recently also received a new request for the medical before getting the green card, which is wrong.
I am confused about your statement that "you have to send your medical record no more than 60 days before you get your green card"
I am not sure I understand. They don't know the date when they will issue your green card in advance and nobody, even them, anticipates the timeline for your application. Otherwise, everybody who submits the medical record automatically gets the green card within 60 days...including those who interfiled. This doesn't make any sense. Can you please clarify what you mean or cite your sources?
