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

Voting in federal elections is a responsibility that is exclusively reserved for United States citizens. This foundational aspect of democracy allows citizens to participate directly in their government by choosing their representatives and influencing legislation. The right to vote is enshrined in various amendments to the U.S. Constitution, emphasizing its importance in ensuring that government reflects the will of the people.

While other choices, such as paying taxes and obeying laws, are obligations that apply to all residents within the United States, regardless of their citizenship status, serving on a jury is also closely tied to citizenship yet is not unique to voting in terms of governmental participation. Therefore, voting stands out as a civic duty that signifies full membership in the polity, highlighting the rights and responsibilities that come with citizenship in the United States.
