What is one responsibility that is only for United States citizens?

Serving on a jury is a responsibility that is specifically reserved for United States citizens. This duty is foundational to the American legal system, reflecting the principle of civic participation and the protection of citizens' rights. Jury service is essential in ensuring that those who are judged in court have their cases decided by their peers—people who share a common understanding of the laws and values of their community.

Though other responsibilities, such as paying taxes and attending school, apply to both citizens and non-citizens, jury duty is unique to citizens due to its implications for civic engagement and the functioning of democracy. Voting in local elections is also restricted to citizens, but jury service stands out as a civic duty requiring direct involvement in the judicial process.
