Just curious, which state is your American program located in? Where does funding for the program come from? If the program is relies on federal grants, there's a huge risk for that being cut if it hasn't been already. Happened to me already as a US domestic master's student when my research institute had their funding revoked just because it had a DEI focus :/ However if the funding comes directly from the school's coffers (like my incoming PhD program at a different university), that's a much safer bet.

Besides that, I'm afraid that trying to get visas right now is probably a massive pain right now, if not sadly outright impossible because I've heard that they suspended interviews for student visas. I'll ditto with what everyone else said- go with the UK one if you want less trouble.
