Which of the following is a right exclusive to United States citizens?

Voting is a right that is exclusive to United States citizens, distinguishing them from non-citizens. This right is fundamental to the democratic processes of the country and is protected by various amendments to the Constitution. Citizens have the ability to participate in elections at local, state, and federal levels, thus influencing government decisions and policies.

While working in federal jobs, receiving social security benefits, and traveling freely between states are important aspects of life in the U.S., they are not rights that are exclusively reserved for citizens. Non-citizens may also have access to certain federal employment opportunities depending on their visa or immigration status, and social security benefits can be received by eligible individuals who have contributed to the system regardless of citizenship. Additionally, the right to travel freely between states applies broadly to all residents, including non-citizens, within the United States.
