Constitutional FAQ Answer #46
Q46. "What amendments should I look at dealing with the duties of citizens to uphold the Constitution?
A. The Constitution deals with the rights of citizens, and not the responsibilities of them. I think what you're looking for is more common law or in the U.S. Code than in the Constitution. You might find some guidance in the Oath of Citizenship, which new citizens take. It can be found on the Citizenship Page.
