What is one right that is only available to United States citizens?

The correct answer is that the right to vote is a privilege exclusive to United States citizens. Voting is a fundamental aspect of participation in the democratic process, enabling citizens to choose their representatives and influence laws and policies. While other options may have varying regulations regarding eligibility, the Constitution and federal law specifically restrict the right to vote to citizens. This ensures that only those who have a legal and vested interest in the country's future can directly shape its governance. For example, non-citizens may have certain rights to work and travel, but they cannot participate in elections or hold federal office. Thus, voting is distinctly tied to citizenship.
