The US does recognize medical degrees from other countries and leans on foreign doctors heavily.

We require them to go through a US residency.

Something like 1/4 of doctors in the US are foreign born.

Residencies are one of the most grueling experiences for human beings ,and a restriction that makes doctors go through that process twice (in their home country and then in the US) amounts to a strong restriction.

Asking an experienced doctor to go through a residency is worse than asking software developers to get a doctorate if they want to write code in the US.

Also, it's not that easy to actually get a place in a US residency, even if you are willing to go through it again.
