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

Voting in federal elections is a responsibility exclusively reserved for United States citizens. This designation underscores the principle of self-governance which is foundational to the democratic system in the U.S. By allowing only citizens to vote, the process ensures that individuals who have affirmed their commitment to the country, its values, and its institutions have a say in how they are governed. Voting is not only a right but also a civic duty that reflects one's participation in the democratic process.

The other responsibilities listed—paying taxes, obeying the law, and attending school—apply to all individuals residing in the United States, regardless of their citizenship status. Non-citizens are also required to follow laws and meet many civic obligations, such as paying taxes, which is essential for the functioning of the government.
