Purpose and Background

A. Purpose

United States laws allow for children to acquire U.S. citizenship other than through birth in the United States. [1] Persons who were born outside of the United States to a U.S. citizen parent or parents may acquire or derive U.S. citizenship at birth. Persons, including adopted children, [2] may also acquire citizenship after birth, but before the age of 18, through their U.S. citizen parents.

Previously, acquisition of citizenship generally related to those persons who became U.S. citizens at the time of birth, and derivation of citizenship to those who became U.S. citizens after birth due to the naturalization of a parent.

In general, current nationality laws only refer to acquisition of citizenship for persons who automatically become U.S. citizens either at the time of birth or after. In general, a person must meet the applicable definition of child at the time he or she acquires citizenship and must be under 18 years of age.

B. Background

The law in effect at the time of birth determines whether someone born outside the United States to a U.S. citizen parent or parents is a U.S. citizen at birth. In general, these laws require a combination of at least one parent being a U.S. citizen when the child was born and having lived in the United States for a period of time. In addition, children born abroad may become U.S. citizens after birth. Citizenship laws have changed extensively over time with two major changes coming into effect in 1978 and 2001.

Before the Act of October 10, 1978, U.S. citizens who had acquired citizenship through birth abroad to one citizen parent had to meet certain physical presence requirements to retain citizenship. [3] This legislation removed all retention requirements.

Before the Act of October 10, 1978, U.S. citizens who had acquired citizenship through birth abroad to one citizen parent had to meet certain physical presence requirements to retain citizenship. [3] This legislation removed all retention requirements.

Before the Child Citizenship Act of 2000 (CCA), [4] effective February 27, 2001, the Immigration and Nationality Act (INA) had two provisions for derivation of citizenship, former INA 320 and former INA 321. [5] The CCA removed INA 321 and revised INA 320 making it the only statutory provision for children under 18 years of age in the United States to automatically acquire citizenship after birth. [6] The CCA also amended INA 322 to provide for applications for naturalization on behalf of foreign-born children who did not automatically acquire citizenship and who reside outside the United States with a U.S. citizen parent. [7]

C. Table of General Provisions

Children born outside the United States may acquire U.S. citizenship in multiple ways. The table below serves as a quick reference guide to the acquisition of citizenship provisions. [8] The chapters that follow the table provide further guidance.
