Chapter 1 - Purpose and Background

A. Purpose​

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.​

P​ersons applying for naturalization based on their time as lawful permanent residents meet the eligibility requirements to become U.S. citizens.​

P​ersons 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.​

M​embers 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.​

B. Background​

Upon the adoption of the U.S. Constitution in 1787, t​he 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.​ [1] 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)​ (​

Chapter 2 - Becoming a U.S. Citizen

A person may derive or acquire U.S. citizenship at birth. Persons who are born in the United States and subject to the jurisdiction of the United States are citizens at birth. Persons who are born in certain territories of the United States also ​may be​ citizens at birth. In general​, but subject in some cases to other requirements, including residence requirements as of certain dates, ​this includes persons born in:​

Puerto Rico on or after April 11, 1899​;​ [1]

Canal Zone or the Republic of Panama on or after February 26, 1904​;​ [2]

Virgin Islands on or after January 17, 1917​;​ [3]

Guam born after April 11, 1899​;​ [4] or​

Commo​nwealth of the Northern Mariana Islands on or after November 4, 1986​.​ [5]

Persons born in American Samoa and Swain​s​ Island are ​generally ​considered nationals ​but not citizens ​of the ​United States.​ [6]

In addition, persons who are born outside of the United States may be U.S. citizens at birth if one or both parents were U.S. citizens at their time of birth.​Persons who are not U.S. citizens at birth may become U.S. citizens through naturalization.​Naturalization is the conferring of U.S. citizenship after birth by any means whatsoever.​

In general, an applicant files a naturalization application and then USCIS grants citizenship after adjudicating the application. ​In some cases, a person may be naturalized by operation of law. This is often referred to as deriving citizenship. In either instance, the foreign citizen or national must fulfill all of the requirements established by Congress. In most cases, a person may not be naturalized unless he or she has been lawfully admitted to the United States for permanent residence.​

Deciding to become a U.S. citizen is one of the most important decisions an immigrant can make. Naturalized ​U.S.​ citizens share equally in the rights and privileges of ​U.S.​ citizenship. ​U.S.​ citizenship offers immigrants the ability to:​

Vote in Federal elections​;​

Travel with a U.S. Passport​;​

Run for elective office where citizenship is required​;​

Participate on a jury​;​

Become eligible for federal and certain law enforcement jobs​;​

Obtain certain State and Federal benefits not available to noncitizens​;​

Obtain citizenship for minor children born abroad​;​ and​

Expand and expedite their ability to bring family members to the United States​.​



See ​INA 302​ (​


See ​INA 303​ ( If the person was born in the Canal Zone, he or she acquired U.S. citizenship at birth if born between February 26, 1904 and October 1, 1979, and one parent was a U.S. citizen at the time of the person’s birth. The Canal Zone ceased to exist on October 1, 1979. See the so-called ​Torrijos​–Carter Treaties (September 7, 1977). If the person was born in the Republic of Panama, but not in the Canal Zone, one parent must have been a U.S. citizen ​parent employed​ by the U.S. Government, or by the Panama Railroad Company, at the time of the person’s birth.​

See section 303 of the Covenant to Establish a Commonwealth of the Northern Mariana Islands in Political Union with the United States of America, Pub. ​L. 94-241 (​48 U.S.C. 1801​ ( section:1801 edition:prelim) OR (granuleid:USC-prelim-title48-section1801)&f=treesort&edition=prelim&num=0&jumpTo=true) note).​ In addition, certain persons in the CNMI who were born before November 4, 1986, and their children if under age 18 on that date, became U.S. citizens at that time. See section 301 of Pub. ​L. 94-241 (​48 U.S.C. 1801​ ( section:1801 edition:prelim) OR (granuleid:USC-prelim-title48-section1801)&f=treesort&edition=prelim&num=0&jumpTo=true) note).​ In addition, the Department of State will issue U.S. passports to persons born in the ​Northern Mariana Islands ​between January 9, 1978 and November 3, 1986, pursuant to a judicial decision holding that such persons are U.S. citizens. See ​Sabangan​ v. Powell​, 375 F. 3d 818 (​9th​ Cir. 2004).​


See ​INA 308​ (​

Chapter 3 - USCIS Authority to Naturalize

It has long been established that Congress has the exclusive authority under its constitutional power to establish a uniform rule of naturalization and to enact legislation under which citizenship may be conferred upon persons.​ [1] Before 1991, naturalization within the United States was a judicial function exercised since 1790 by various courts designated in statutes enacted by Congress under its constitutional power to establish a uniform rule of naturalization.​

As of October 1, 1991, Congress transferred the naturalization authority to the Attorney General (now the Secretary of DHS).​ [2] USCIS is authorized to perform such acts as are necessary to properly implement the Secretary’s authority.​ [3] In certain cases, an applicant for naturalization may choose to have the Oath of Allegiance​ [4] administered by USCIS or by an eligible court with jurisdiction. Eligible courts may choose to have exclusive authority to administer the Oath of Allegiance. ​
