U.S. Citizenship and Immigration Services (USCIS) Civics Practice Test

The responsibility that is only for United States citizens is voting in federal elections. Voting in elections is a fundamental right and duty exclusive to citizens, reflecting the principle of democracy where citizens have the power to influence their government and decision-making through the electoral process. This responsibility allows citizens to choose their representatives and participate in the governance of the country.

While paying taxes and obeying laws are responsibilities that apply to both citizens and non-citizens residing in the U.S., these do not uniquely define citizenship. Defending the country, although primarily a responsibility of citizens, can also involve non-citizens in certain circumstances, such as lawful permanent residents enlisting in the military. Voting, however, remains a distinct privilege granted solely to citizens, making it a key aspect of democratic engagement and civic duty.
