Which responsibility is exclusive to United States citizens?

Voting in federal elections is a responsibility that is exclusive to United States citizens. This means that only individuals who are citizens, not lawful permanent residents or non-citizens, have the right to participate in the electoral process by casting their votes for federal candidates. This privilege underscores the idea that citizenship comes with certain civic duties and rights, and voting is often seen as one of the most significant expressions of democratic participation.

While the other responsibilities mentioned, such as paying taxes, serving on juries, and running for office, are also important civic duties, they are not exclusive to citizens in the same way. For instance, non-citizens are generally required to pay taxes if they earn income in the U.S., and some jurisdictions allow non-citizens to serve on juries or run for local office under certain conditions. Voting, however, remains a clear marker of citizenship and is reserved for those who have completed the naturalization process or were born as citizens. This distinction is vital to understanding the broader framework of civic responsibility within a democratic society.
