Question

Are there any restrictions on buying a .ir (IRAN) domain from the US? Would I be violating any laws?

Answer 1

According to Wikipedia:

Generally open for Iranians and non-Iranians; 3rd-level registrations under subdomains have varied restrictions and are restricted to Iranian-related entities

There are no law preventing the registration of foreign TLDs including those assigned to Iran.
