What is one right only for United States citizens?

The right to vote in federal elections is specifically reserved for United States citizens. This right is fundamental to the functioning of a democratic society, allowing citizens to participate in the electoral process, choose their representatives, and influence government policies. Voting is a critical means for citizens to express their opinions and impact the decisions that affect their lives and communities.

Other rights listed, such as free speech, the right to bear arms, and the right to a fair trial, are granted to all individuals within the U.S., including permanent residents and some visitors, under the Constitution. These rights are essential for maintaining personal freedoms and ensuring justice, but they are not exclusive to citizens. Thus, the correct answer highlights a distinct privilege that is only accessible to those who have attained U.S. citizenship.
