What is one promise you make when you become a United States citizen?

When you become a United States citizen, one of the promises you make is to serve in the U.S. military if needed. This commitment is part of the Oath of Allegiance, which underscores the responsibilities and obligations that come with citizenship. Service in the military reflects a dedication to the country and its defense, highlighting the expectation that citizens will support and protect the United States.

Other choices, while important aspects of citizenship, do not specifically represent a promise made during the naturalization process. For example, paying taxes and following laws are fundamental responsibilities of all citizens, but they are not formal promises made in the Oath of Allegiance. Voting in elections is a right and an important civic duty, but it is not mandatory that every citizen votes in every election—thus it is not part of the oath.
