What is one promise you make when you become a US citizen?

When you become a U.S. citizen, one of the key promises you make is to give up loyalty to other countries. This pledge is a fundamental part of the Oath of Allegiance that new citizens take, which emphasizes fidelity and primary allegiance to the United States. By renouncing any prior allegiances, citizens affirm their commitment to the United States and its values, laws, and Constitution.

This promise reflects the importance of unity and a shared identity among citizens, which is essential for the functioning of a democratic society. In contrast, serving in the military, educating others about American history, or committing to travel abroad do not encompass the primary obligation associated with citizenship, which centers on loyalty and allegiance to one's country.
