How Communist or Totalitarian Party Membership Affects Eligibility for Naturalized U.S. Citizenship
To obtain U.S. citizenship, applicants must prove adherence to the U.S. Constitution and commitment to orderly change.
The application form that green card holders must fill out in order to apply for U.S. citizenship (Form N-400, Application for Naturalization), asks various questions about group and party memberships. First, it asks an open-ended question about whether applicants have been members of any organization, association, or other type of club or group. Then the form asks specifically whether the applicant is or has ever been a member of or in any way associated (either directly or indirectly) with the Communist Party or any other totalitarian party, or ever advocated (either directly or indirectly) the overthrow of any government by force or violence.
Saying âyesâ or otherwise indicating membership in or advocacy for the Communist Party or any totalitarian or similar party can result in denial of oneâs application for U.S. citizenship. This all relates to the portion of U.S. immigration law that requires citizenship applicants to show that they are attached to the principles of the U.S. Constitution and well-disposed to the nationâs good order and happiness. (See I.N.A. § 316(a).) This includes a belief in representative democracy and the basic premise that political change should be brought about in an orderly fashion.
