From what I see, the FCC Amateur radio license requires a US mail address.. I wonder what foreigners are doing for that, if all get a postbox or use the address of friends.
Maybe @jimt or someone else knows?

EDIT: adding background, for all who wondered :)
I'm a German living in Japan, passing the local exams requires different language skills than passing the FCC ones, and then converting into a Jap. license. I passed the Jap. class 4, but for all terms distinct Jap. vocab is used...
