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 civic duty ensures that the legal system is upheld fairly, with jurors selected from those who have a stake in the rights and responsibilities of citizenship. The role of a juror involves making decisions based on the law and facts presented during a trial, and this process relies on individuals who are fully vested in the nation, embodying an understanding of the legal framework of the United States.

While paying taxes, obeying laws, and defending the Constitution are important responsibilities, they apply to all residents within the jurisdiction, including non-citizens in certain contexts. However, the act of serving on a jury fundamentally requires an individual to have full citizenship status, as jurors must demonstrate a commitment to the principles of justice and civic responsibility that are integral to the rights of citizenship in the U.S.
