Hmm, I think OpenSRS needs to update their docs on the subject as they fail to state anything about a nameserver requirement.
The OpenSRS site lists the following information about .US registration requirements: http://www.opensrs.org/dotus_info.shtml states "You should be aware that .us is a closed registry. Only individuals and organizations that meet U.S. presence requirements (Nexus requirements) can register domains. (For more information on U.S. presence requirements see http://www.opensrs.org/dotus_timelines.shtml#requirements)" http://www.opensrs.org/dotus_timelines.shtml#requirements states "Prospective registrants in the usTLD must fall in one of three U.S. Nexus categories and must certify that they have a "bona fide presence in the United States." Prospective registrants must indicate their use of the domain by selecting one of the following categories:" and then lists the three Nexus categories with no mention of name servers being located in the U.S. OpenSRS' .US FAQ at http://www.opensrs.org/dotus_FAQ.shtml states "Who can register a .US domain name? Any U.S. citizen or resident, as well as any business or organization, including federal, state, and local government with a bona fide presence in the United States can register a .US domain name."
