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

Voting in elections is a responsibility that is exclusive to United States citizens. While non-citizens can contribute to society in many meaningful ways, such as paying taxes and obeying laws, the right to vote is fundamentally tied to citizenship in the U.S. This exclusivity places a significant emphasis on the concept of civic engagement, where citizens have the opportunity to influence government decisions and policies through their electoral choices. Voting helps ensure that the government reflects the will and interests of its citizens, making it a core responsibility of citizenship.

Other activities such as paying taxes and obeying laws are requirements for all people living in the United States, regardless of their citizenship status. Serving on a jury is also a civic duty that primarily engages citizens. However, it is the act of voting that distinctly requires citizenship, reinforcing the idea that only those who are full members of the political community have a voice in shaping the governance of that community.
