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 duty is significant as it plays a vital role in the judicial system, ensuring that trials are conducted fairly and that defendants are evaluated by a group of their peers. Jurors must be U.S. citizens because they are tasked with making judgments based on legal standards and the rule of law, which reflects the values and rights established within the U.S. Constitution.

In contrast, pursuing an education, paying taxes, and voting in state elections can be fulfilled by both citizens and non-citizens, although voting in federal elections is strictly for citizens. Education is a fundamental right that is accessible to everyone in the U.S., while paying taxes is a financial obligation that applies to many individuals living and working in the country, regardless of their citizenship status. Voting in state elections is also generally reserved for citizens, but there may be some local jurisdictions where non-citizens can vote on specific matters. Therefore, serving on a jury remains the clear responsibility that is exclusively held by U.S. citizens.
