What is Naturalization? How to Apply for US Citizenship and Naturalization

Applying for US Citizenship and Naturalization

Naturalization is the process in which people who were born outside of the United States become U.S. citizens. Through the process of naturalization, you are granted lawful permanent residency from the United States Citizenship and Immigration Services (USCIS). To apply, you must meet the set requirements established by Congress in the Immigration and Nationality Act.

Difference Between Naturalization and Acquisition of Citizenship

The biggest difference between naturalization and citizenship through acquisition is the process in how one becomes a citizen. Naturalization is the act of applying for citizenship for those over 18. Acquisition of citizenship is for someone who attains citizenship because they are:

  • Born in the United States or a U.S. Territory
  • Born to parents who are U.S. Citizens

For example, if an immigrant couple went through the naturalization process, they are now U.S. citizens because they completed the application process. Their child, however, does not have to go through the naturalization process (if they are under 18). The child’s parents can fill out a form to grant citizenship to their child. Thus, the child acquires citizenship through their relationship with their parents.

Lawful U.S. citizenship can be granted through the naturalization process or acquisition of citizenship. The difference is that acquisition is given because of the person’s relationship to U.S. citizens, whereas naturalization requires a set of requirements for adults.


If you are not a citizen by birth and haven’t acquired U.S. citizenship by any other means, you will need to review the Naturalization Eligibility Worksheet to determine if you are eligible to apply.

The first three questions to determine eligibility for naturalization are:

  1. Am I at least 18 years old?
  2. Am I a Permanent Resident of the United States and hold a permanent residency card?
  3. Have I been a permanent resident for at least five years (or 3-5 years under certain circumstances?

There are 15 total questions in determining your naturalization application eligibility. Make sure you can answer yes to all questions. Speak with your immigration lawyer about qualifications and if you meet requirements to apply for US citizenship.
