Which of the following restrictions apply when a non-licensed person speaks to a foreign amateur radio station via a station under the control of an FCC-licensed amateur radio operator?

When an unlicensed person speaks over an amateur radio station, they are participating in third-party communications. If the communication is with a foreign amateur station, international regulations apply. The primary restriction is that the foreign station must be located in a country that has a formal third-party communications agreement with the United States. Without this treaty, passing messages on behalf of an unlicensed person to that country is strictly forbidden. The distractors are incorrect because U.S. citizenship is not a requirement to be a third party, and the unlicensed person is actually permitted to speak the station identification as long as the licensed control operator is present and directly supervising.
