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

Serving on a jury is a responsibility exclusively reserved for United States citizens. This duty is significant within the U.S. legal system, as juries are a vital component of ensuring justice in a trial by providing a fair and impartial deliberation of cases. The Constitution guarantees the right to a jury trial, and it is deemed essential that only citizens serve on juries. This helps to uphold the integrity of the legal process and reinforces the idea that those who are making judgments about legal matters are also those who have a stake in the community and its governance.

In contrast, while the other responsibilities such as paying taxes, obeying the law, and attending school are important, they apply to all residents regardless of citizenship status. Non-citizens, for example, are still required to obey the law and can also be subject to taxation, reflecting their legal presence in the country.
