What is one right that is reserved for United States citizens?

The right that is specifically reserved for United States citizens is the ability to run for federal office. This right is established in the U.S. Constitution and is critical for ensuring that those who represent the interests of citizens in government positions, such as the Senate and the House of Representatives, are themselves citizens. While many rights, such as freedom of speech and the right to bear arms, are granted to all individuals residing in the U.S., the opportunity to run for federal office is a privilege that is exclusive to citizens. This distinction emphasizes the importance of citizenship in participating fully in the democratic process and in holding positions of significant responsibility within the government.
