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 obligation is seen as a fundamental aspect of civic duty in the American legal system. When citizens serve on juries, they participate directly in the judicial process, helping to uphold justice and ensuring that legal decisions are made by their peers. This involvement reinforces the principle of a government "of the people, by the people, and for the people."

In contrast, while paying taxes, participating in elections, and obeying the law are all important responsibilities, they are not exclusively required of citizens. Legal residents may also be obligated to pay taxes and are expected to follow the law, whereas non-citizens may have the opportunity to vote in local elections in some jurisdictions but are not permitted to participate in federal elections. Thus, jury service stands out as a unique obligation tied specifically to citizenship.
