When CB radios became the fad of the year, I looked into getting one. I was surprised to find that the "Citizen" part of the name was a legal requirement. Since I'm a resident alien ex-pat Brit, I couldn't legally have one.
I don't know if some other odd rules still apply. As an alien, I couldn't own an airplane but I could use the two-way radio when flying as a passenger. I could own a boat but wasn't allowed to use its two way radio.
