US Citizenship Requirements

Understanding US 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.

How to Become a United States Citizen

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

  • Those born outside United States borders if one or both parents are United States citizens at the time of the birth. 
  • 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.
