US Citizenship Requirements

Understanding U.S. Citizenship requirements is important if you want to navigate the naturalization process successfully. Use this guide to determine if you are eligible to become a US Citizen.

U.S. Citizenship Requirements

U.S. Citizenship is first and foremost derived from one’s birthplace. People who are born within the United States boundaries become subject to the laws and jurisdiction of the United States as citizens from birth. Those born within territories held by the United States may be citizens at birth but also may be subject to residency requirements.

Those born in American Samoa and Swains Island are generally considered nationals but not regarded as citizens of the United States. 

Additional Ways To Become A United States Citizenship

If you were born outside of U.S. borders, but one of both of your parents are United States Citizens, you are eligible for Citizenship.

By operation of law - seek legal advice for this Citizenship option. 

Those who are not United States Citizens at birth may opt to become a citizen through the process of naturalization. Naturalization is defined as conferring U.S. citizenship to someone after birth by any means. A naturalization application is submitted to the United States Citizenship & Immigration Service (USCIS) and meets the criteria established by the United States Congress.

Citizenship and Naturalization Requirements

If you were not born in the United States, naturalization is the process that a person goes through to become a United States citizen. To complete the naturalization process, you must meet the following requirements:

  • Be 18 Years Old – at the time of filing your N-400 Naturalization Applications.
  • Be a Permanent Resident – having a green card for at least 5 years.
  • Have Continuous Residence – maintaining a permanent home in the United States for at least 5 years before filing your application.
  • Adequate Physical Presence – you  must have been physically present in the U.S. for at least 30 months out of the last 5 years

Exceptions to Eligibility Requirements

The Immigration and Nationality Act allows certain exceptions to the continuous residence requirement for those applicants working abroad for -

  • The United States government, including the Military.
  • An acknowledged American institution of research
  • Contractors of the United States government
  • An international organization that is public
  • An organization that meets the requirements delineated in the International Immunities Act

If a citizenship applicant seeks to preserve their continuous residence (for naturalization purposes) while employed outside the United States by one of the above-noted recognized institutions, simply file a Form N-470. Form N-470 is an application to preserve residence for naturalization purposes with the United States Citizenship & Immigration Service.  

Any company/organization may obtain United States Citizenship & Immigration Service recognition as an American Institution of Research to allow employees to preserve their continuous residence status for its employees who are assigned out of United States'  borders for a significant amount of time. The company or organization seeking this status should follow the instructions found here - Requesting Recognition as an American Institution of Research.

The Background Investigation

The United States Citizenship & Immigration Service conducts an investigation of the applicant. The investigation consists of a criminal background and security checks. The security checks included in the U.S. citizenship processes include:

  • The collection of collecting fingerprints 
  • A "name check" performed by the Federal Bureau of Investigations (FBI). 
  • The USCIS performs other inter-agency criminal background and security checks, as well.  

All naturalization applicants must sit for an in-person examination before a United States Citizenship & Immigration Service officer. The citizenship applicant's examination includes both an interview and the administration of United States Citizenship required tests. The applicant's interview is a fundamental component of the naturalization examination.

The officer places the applicant under oath before interviewing them.  The initial naturalization examination includes –

  • The review of information provided in the application and questions relating to the applicant’s eligibility for naturalization
  • The administration of tests to meet naturalization requirements

The written responses by the citizenship applicants regarding the answers to the question included in the applicant's application initially submitted. It is noted that the answers provided by a citizenship applicant under penalty of perjury.

Each citizenship application differs so that the USCIS officer may choose to:

  • Record the face-to-face interview as established by the USCIS.  A mechanical, electronic, or videotaped device are all permitted
  • Have a transcript written for the discussion
  • Prepare a citizenship affidavit regarding the testimony of the applicant during the face-to-face interview process. The freedom of Information Act (FOIA) permits either the applicant or his or her authorized attorney or representative may request a copy of the record of proceedings. 

USCIS may schedule an applicant for a re-examination if need to be to determine the applicant’s eligibility

The Oath of Allegiance

The final act of naturalization includes the oath of allegiance in a public ceremony to the U.S. government and Constitutions.
