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

Serving on a jury is a responsibility exclusively reserved for United States citizens. This civic duty is integral to the judicial system, where jury members participate in determining the outcome of legal cases. It ensures that a jury of one's peers, who have a vested interest and stake in the community, are the ones evaluating evidence and making judgments in legal proceedings.

While paying taxes is an important obligation for all residents, including non-citizens in some cases, and obeying traffic laws is a requirement for everyone on the road, these responsibilities are not confined solely to citizens. Voting in local elections is also a right specifically granted to citizens, but the option regarding jury service distinctly emphasizes a legal obligation that is a fundamental aspect of citizenship in the United States.
