Citizenship

Certain individuals born outside of the United States are born citizens because of their parents, according to the principle of jus sanguinis (which holds that the country of citizenship of a child is the same as that of his / her parents). The U.S. Congress is responsible for enacting laws that determine how citizenship is conveyed by a U.S. citizen parent or parents.

Naturalization

Naturalization is the process by which U.S. citizenship is conferred upon a foreign citizen or national after he or she fulfills the requirements established by Congress in the Immigration and Nationality Act (INA). The general requirements for administrative naturalization include:

• a period of continuous residence and physical presence in the United States;
• residence in a particular USCIS District prior to filing;
• an ability to read, write, and speak English;
• a knowledge and understanding of U.S. history and government;
• good moral character;
• attachment to the principles of the U.S. Constitution; and,
• favorable disposition toward the United States.

All naturalization applicants must demonstrate good moral character, attachment, and favorable disposition. The other naturalization requirements may be modified or waived for certain applicants, such as spouses of U.S. citizens. 

General Naturalization Requirements

Applicants must be at least 18 years old.

An applicant must have been lawfully admitted to the United States for permanent residence. Lawfully admitted for permanent residence means having been legally accorded the privilege of residing permanently in the United States as an immigrant in accordance with the immigration laws. Individuals who have been lawfully admitted as permanent residents will be asked to produce an I-551, Alien Registration Receipt Card, as proof of their status.
