Derivative citizenship is U.S. citizenship given to lawful permanent resident children (with green cards) whose parents become naturalized U.S. citizens; or in recent years, to foreign-born children adopted by U.S. citizen parents, if certain conditions are met.
(To say that the parents "naturalized" means that they started as U.S. lawful permanent residents, then went through an application and exam process to obtain U.S. citizen status.)
Here, we'll explain more about how derivative citizenship works.
Does Someone Need to Apply for Derivative U.S. Citizenship?
When a person gets derivative U.S. citizenship, it happens automatically, by operation of law. Neither the parent nor the child needs to submit an application. However, the legal requirements for derivative citizenship are highly complex and have changed a lot over the years, so it can be difficult to determine whether you qualify. You must, in most cases, follow the law that applied in the year you were born.
And because derivative citizenship is automatic, you won't have proof of your status unless you separately apply to U.S. Citizenship and Immigration Services (USCIS) for a citizenship certificate (discussed below).
How Derivation of Citizenship Differs From Acquisition of Citizenship
There have always been two important elements of derivative citizenship. These are naturalization of the U.S. parent or parents before the child has reached a certain age (unless the parent was born a citizen) and the child becoming a lawful permanent resident before a certain age. Other requirements have been added (or subtracted) at different times.
Another legal concept known as "acquisition of citizenship" applies to children born outside the United States to one or more U.S. citizen parents. These children did not need to enter the United States with a green card in order to obtain citizenship automatically; they are, if they meet the legal criteria that applied in the year they were born, citizens at birth. (See articles on Acquiring or Deriving Citizenship Through Parents for details.)
Latest Version of Derivation of Citizenship in the Child Citizenship Act
The Child Citizenship Act (CCA) is the current law on derivation of citizenship, which is in effect for children born or adopted today or at any time since February 28, 1983. It went into effect on February 27, 2001. You'll find it in Section 320 of the Immigration and Naturalization Act (I.N.A.).
The CCA allows foreign-born, biological, and adopted children of U.S. citizens to get American citizenship automatically when they enter the United States as lawful permanent residents. Under the CCA, a child will automatically become a U.S. citizen on the date that all of the following requirements are met:
- at least one parent is a U.S. citizen, whether by birth or naturalization
- the child is under age 18
- the child is unmarried
- if the child was born out of wedlock, the mother is the U.S. citizen or, if the father is a U.S. citizen through naturalization or other means, the child was legitimated by the father under either the law of the child’s or father’s residence or domicile, and the legitimation occured before the child turned 16
- the child is currently residing in the United States (or in some cases, overseas, if the parent is in the U.S. armed forces or working for the U.S. government) and is in the legal and physical custody of a U.S. citizen parent, and
- the child is a lawful permanent resident (a green card holder).
Additional criteria apply if the child is adopted.
Adopted Children and Derivation of U.S. Citizenship
A child who enters the U.S. on an IR4 visa (to be adopted in the U.S.) will acquire American citizenship when the adoption is full and final in the United States. A child who was not an orphan will also need to have been adopted before turning 16 and have been in the legal custody of and have resided with the adopting parent(s) for at least two years beforehand.
The Law on Derivation of Citizenship Before the CCA
If you are interested in finding out about possible derivation of citizenship and were born prior to 1983, the Immigrant Legal Resource Center offers useful charts. Note, however, that derivation of citizenship for adopted children did not exist prior to the passage of the CCA.
Obtaining Proof of U.S. Citizenship
If your child permanently resides in the United States and meets the requirements for derivative citizenship, you can apply for proof of citizenship by filing USCIS Form N-600 (Application for Certificate of Citizenship), along with documents proving the parent's U.S. citizen status, the child's identity and immigration status and relationship to the parent (using a birth certificate or adoption decree), and more (depending on the particulars of your case).
The form itself is available for free download from the USCIS website. However, you'll need to pay a filing fee (As of April 1, 2024, $1,385 for online filing and $1,335 for paper filing) and submit it by mail, then wait for a reply. The wait can be months long. USCIS may require the parents and child to appear for a personal interview.
Another option is to apply to the U.S. Department of State for the child's passport. However, depending on timing, it's sometimes easier to obtain a citizenship certificate from USCIS first, and use that to prove the person's status to the Department of State. The latter agency is less accustomed to making decisions on derived citizenship.
