Do you believe in the U.S. Constitution?

When the USCIS officer asks whether the applicant believes in the U.S. Constitution, the standard expected answer is "Yes." The question is part of confirming that the applicant is attached to the principles of the Constitution and well-disposed to the good order and happiness of the United States, a long-standing requirement of naturalization codified in section 316(a) of the Immigration and Nationality Act. The Oath of Allegiance includes the explicit promise to support and defend the Constitution against all enemies, foreign and domestic.

The applicant does not need to be a constitutional scholar to answer this question or to take the Oath. The basic commitment is to the values and principles the Constitution embodies: the rule of law, separation of powers, checks and balances, federalism, individual liberties protected by the Bill of Rights, and the consent of the governed expressed through democratic institutions.

Applicants who hold views fundamentally inconsistent with the Constitution may face problems. Section 313 of the Immigration and Nationality Act bars from naturalization those who advocate world communism, the overthrow of the U.S. government by force or violence, the assassination of officers, and similar revolutionary aims. Members of the Communist Party or other totalitarian parties may face presumptive ineligibility, with exceptions for involuntary, technical, or non-meaningful membership and for those who have left the party for at least 5 years before applying (or 10 years for some categories).

The applicant is not required to renounce the political and constitutional traditions of the home country (which may be entirely democratic), only to commit to American constitutional principles. Applicants from countries with constitutions or political traditions different from the American (monarchies, theocracies, communist states, authoritarian regimes) are welcome to seek citizenship, and many do. The personal political views of the applicant do not generally bar citizenship; conservatives, liberals, libertarians, socialists, and others have all become naturalized citizens.

What matters is the commitment to the constitutional process: peaceful change through elections, courts, and lawmaking rather than through revolution or violence. Applicants are not asked to support any particular policy, party, or interpretation of the Constitution, only to commit to the basic framework.

The interview typically does not include extensive discussion of the applicant's views; a "Yes" answer is normally sufficient. Officers may ask follow-up questions if there is something specific in the application or background that raises concern, such as past membership in a totalitarian party or apparent sympathy with anti-democratic groups. Applicants with such concerns should consult an immigration attorney. The vast majority of applicants have no difficulty answering this question.
