What rights, duties, and obligations does American citizenship entail?

Answer 1

Beyond jury duty - I cannot think of any obligations. One of the most important rights of citizenship to the ability to vote.

Of course for many immigrants the most important thing about citizenship is the fact that they can say that they are an American Citizen.

Answer 2

Well, lets see the right to pay taxes(on everything and I mean everything), The right to have your rights walked on(being sued for someone falling in your yard is an example). The right to have your tax money wasted on re elections for politics, The right that you could serve in the military if they think there should be a draft, The right to learn spanish for illegal immigrants that do not pay tax money but yet get money from taxes.
