While US has ratified the Universal Declaration of Human rights[1], I am not sure how binding it is. There are also two Conventions about statelessness that US has not signed, and maybe that’s why similar revocations of citizenship has happened in the past[2] Even though link discusses a case where a terrorist lost the citizenship, not a law-abiding doctor, the grounds for revocation were the same - diplomatic immunity at the time).

Thanks for the links! Very informative

I looked over the universal declaration of human rights and didn't see anything about statelessness, but the UNHCR has a page on it: https://reporting.unhcr.org/spotlight/statelessness

It has an article about everyone having the right to have a nationality, so I suppose making anyone stateless would be against it? See article 15 https://www.un.org/en/about-us/universal-declaration-of-huma...
