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

One responsibility that is exclusive to United States citizens is the obligation to support and defend the Constitution. This requirement emphasizes the unique commitment of citizens to uphold the foundational legal framework of the country, ensuring that rights and liberties enshrined in the Constitution are protected. By engaging in this responsibility, citizens affirm their dedication to the principles of democracy and the rule of law, which are central to the American identity.

In contrast, while paying taxes, following laws, and respecting others' rights are important civic duties, they are responsibilities shared by both citizens and non-citizens residing in the United States. For example, legal residents and visitors are also required to adhere to laws and regulations as part of their presence in the country. However, the role of supporting and defending the Constitution is a hallmark of citizenship, highlighting the distinct and active role that citizens play in sustaining the democratic framework of the United States.
