The United States has a long history of welcoming immigrants from all parts of the world. The United States values the contributions of immigrants who continue to enrich this country and preserve its legacy as a land of freedom and opportunity. USCIS is proud of its role in maintaining our country’s tradition as a nation of immigrants and will administer immigration and naturalization benefits with integrity.
United States citizenship is a unique bond that unites people around civic ideals and a belief in the rights and freedoms guaranteed by the U.S. Constitution. The promise of citizenship is grounded in the fundamental value that all persons are created equal and serves as a unifying identity to allow persons of all backgrounds, whether native or foreign-born, to have an equal stake in the future of the United States.
This volume of the USCIS Policy Manual explains the laws and policies that govern United States citizenship and naturalization.
USCIS administers citizenship and naturalization law and policy by:
Providing accurate and useful information to citizenship and naturalization applicants;
Promoting an awareness and understanding of citizenship; and
Adjudicating citizenship and naturalization applications in a consistent and accurate manner.
Accordingly, USCIS reviews benefit request for citizenship and naturalization to determine whether:
Foreign-born children of U.S. citizens by birth or naturalization meet the eligibility requirements before recognizing their acquisition or derivation of U.S. citizenship.
Persons applying for naturalization based on their time as lawful permanent residents meet the eligibility requirements to become U.S. citizens.
Persons applying for naturalization based on their marriage to a U.S. citizen meet the eligibility requirements for naturalization through the provisions for spouses of U.S. citizens.
Members of the U.S. armed forces and their families are eligible for naturalization and ensure that qualified applicants are naturalized expeditiously through the military provisions.
Persons working abroad for certain entities, to include the U.S. Government, meet the eligibility requirements for certain exceptions to the general naturalization requirements.
Volume 12, Citizenship and Naturalization, contains detailed guidance on the requirements for citizenship and naturalization.

Upon the adoption of the U.S. Constitution in 1787, the first U.S. citizens were granted citizenship status retroactively as of 1776. Neither an application for citizenship, nor the taking of an Oath of Allegiance was required at that time. See Franklin, F. (1906). The Legislative History of Naturalization in the United States; From the Revolutionary War to 1861. Chicago: The University of Chicago Press. Persons only needed to remain in the United States at the close of the war and the time of independence to show that they owed their allegiance to the new Government and accepted its protection.
The following key legislative acts provide a basic historical background for the evolution of the general eligibility requirements for naturalization as set forth in the Immigration and Nationality Act (INA).
