Are you sure it was them? Having a verified personal identity is not a requirement to have a .us domain. All you need to prove is that you have "a bona fide presence in the United States of America or any of its possessions or territories [Nexus Category 3]."
(It goes into detail claiming that you need to "state" your country of citizenship, but not that you need to "prove" your country of citizenship. An identity document is massively overreaching, IMHO. I never had to prove anything to get jrock.us, and if I have to, I will move the domain.)
