What Is the Purpose of Form N-600?

NOTE: You are not required to obtain evidence of your U.S. citizenship. If you want evidence of your U.S. citizenship
you may submit Form N-600 to obtain a Certificate of Citizenship from USCIS, or you may apply for a U.S. passport with
the Department of State. See travel.state.gov for more information.

Who Should File Form N-600?
You should file this application if:

1. You are requesting a Certificate of Citizenship because you were born outside the United States to a U.S. citizen
parent; or
2. You are requesting a Certificate of Citizenship because you automatically became a citizen of the United States after
birth, but before you turned 18 years of age. (A parent or legal guardian can also file Form N-600 on behalf of a
minor child.)
To file this application, you must be the child of a U.S. citizen parent. USCIS recognizes the following parent-child
relationships for citizenship purposes:
•

The biological child of a U.S. citizen parent. (Your U.S. citizen parent must also be your legal parent. If the U.S.
citizen parent is your biological father, you will generally have to establish that you were born in wedlock or
legitimated. In some cases, you may be able to provide a court order establishing paternity or evidence that your
father acknowledged paternity in writing under oath instead of legitimation.)

•

The adopted child of a U.S. citizen parent.

•

The child of a non-genetic gestational U.S. citizen parent (person who carried and gave birth to the child) who is
also your legal parent.

•

The child of a U.S. citizen parent who was married to your genetic or gestational parent at the time of your birth
(even if no genetic or gestational relationship exists with the U.S. citizen parent) and both of your parents are also
your legal parents.

NOTE: Stepchildren CANNOT acquire U.S. citizenship unless adopted.
Citizenship law has changed over the years and different laws apply to determine whether you automatically became a
U.S. citizen at birth. If you are claiming U.S. citizenship based on your birth outside the United States to a U.S. citizen
parent, the law in effect on the date of your birth applies. Different provisions may apply depending on whether you were
born in wedlock or out-of-wedlock.
If you are claiming U.S. citizenship after birth, but before you reached 18 years of age, the law that applies to you is the
law in effect when the last qualifying condition was met. Generally, the conditions are listed below:
These conditions must be met before you turn 18 years of age:
1. Your parent must be a U.S. citizen;
2. You must establish one of the parent-child relationships listed in Part 1., Item Number 2. of Form N-600;
3. You must be lawfully admitted to the United States for lawful permanent residence; and
Form N-600 Instructions 08/10/22 

Page 1 of 12

4. You must be living in the United States in the legal and physical custody of your U.S. citizen parent.
NOTE: If you are the child of: (1) a U.S. government employee; (2) a spouse of a U.S. government employee; (3) a
member of the Armed Forces of the United States; or (4) a spouse of a member of the Armed Forces of the United States,
and your parent is stationed outside of the United States, you may be exempt from the requirement to be living in the
United States if you meet the conditions described in Section 320(c) of the Immigration and Nationality Act.
You can file Form N-600 at any time if you became a U.S. citizen at birth or before you turned 18 years of age. Filing this
application is NOT a request to become a U.S. citizen. Filing this application is ONLY a request to obtain a Certificate of
Citizenship which recognizes that you became a citizen on a particular date.
Adopted Child

An adopted child may also acquire U.S. citizenship through their adoptive U.S. citizen parent depending on the law being
applied. Currently, an adopted child can acquire U.S. citizenship through their U.S. citizen parent.
NOTE: If you are now over 18 years of age, but all of the above conditions apply to you before your 18th birthday and
you were under 18 years of age on February 27, 2001 (the date the law took effect), you may file this application to obtain
a Certificate of Citizenship.
You may file this application if:

1. You claim to have acquired U.S. citizenship through a U.S. citizen parent and are now over 18 years of age; or
2. You are the U.S. citizen parent or legal guardian who has legal and physical custody of child (under 18 years of age).
Law in Effect at the Time of Your Birth or While Under Age 18

To determine if you were born a U.S. citizen, U.S. Citizenship and Immigration Services (USCIS) must look at the law
that was in effect at the time of your birth. To determine if you acquired citizenship after birth, USCIS generally must
look at the law in effect before you turned 18. The law currently in effect, the Child Citizenship Act (CCA), applies only
to those children born on or after February 27, 2001, or those who were under 18 years of age as of that date.

Who Should Not File Form N-600?
You should not file this application if:

1. You do not have at least one U.S. citizen parent;

2. Your parent-child relationship does not satisfy one of the categories listed in Part 1., Item 2. of Form N-600;
3. You are seeking to replace a certificate you lost or that was stolen. Refer to Form N-565, Application for Replacement
Naturalization/Citizenship Document, for information to replace a lost or stolen certificate; or
4. You already filed Form N-600 and received a decision from USCIS on that previously filed Form N-600. USCIS will
reject (not accept) any subsequently filed Form N-600. Review your Form N-600 denial notice for more information.
NOTE: If you are under 18, are the child of a U.S. citizen parent, you regularly reside outside the United States, and you
did not acquire U.S. citizenship at birth under INA sections 301 or 309, your U.S. citizen parent, U.S. citizen grandparent,
or U.S. citizen legal guardian may need to file Form N-600K, Application for Citizenship and Issuance of Certificate
Under Section 322, instead of Form N-600. Please review the Instructions for Form N-600K to determine whether you
should file that form instead of Form N-600. If you are over 18, do not file Form N-600K.

ASC, instead of your child signing for themselves.

Provide legitimation documentation from the country or state in which you were legitimated. Legitimation can be
established according to the laws of your father’s residence or your residence. If you were born out of wedlock and
are claiming citizenship at birth through your U.S. citizen father, instead of proving legitimation, you may provide
proof that your father acknowledged paternity of you in writing under oath, or your paternity has been established by
adjudication of a competent court.

may request an original typed or printed statement from the appropriate government or other legal authority to support
your claim that the documents are unavailable.
