Form N-600

OMB No. 1615-0057
Expires 08/31/2024

What Is the Purpose of Form N-600?
Form N-600, Application for Certificate of Citizenship, is an application for a Certificate of Citizenship.
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

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.

accept a stamped or typewritten name in place of a signature. If you are under 14 years of age, your parent or legal
guardian may sign the application on your behalf. A legal guardian may also sign for a mentally incompetent person.
If the request is not signed or if the requisite signature on the request is not valid, USCIS will reject the request.
See 8 CFR 103.2(a)(7)(ii)(A). If USCIS accepts a request for adjudication and determines that it has a deficient signature,
USCIS will deny the request.
Validity of Signatures. USCIS will consider a photocopied, faxed, or scanned copy of the original, handwritten signature
valid for filing purposes. The photocopy, fax, or scan must be of the original document containing the handwritten, ink
signature.
Filing Fee. Each application must be accompanied by the appropriate filing fee. (See the What Is the Filing Fee section
of these Instructions.)
Evidence. At the time of filing, you must submit all evidence and supporting documents listed in the What Evidence
Must You Submit and/or Specific Instructions sections of these Instructions.
Biometric Services Appointment. USCIS may require that you (the applicant/child) appear for an interview or provide
biometrics (fingerprints, photograph, and/or signature) at any time to verify your identity, obtain additional information,
and conduct background and security checks, including a check of criminal history records maintained by the Federal
Bureau of Investigation (FBI), before making a decision on your application or petition. After USCIS receives your
application and ensures it is complete, we will inform you if you need to attend a biometric services appointment. If an
appointment is necessary, the notice will provide you the location of your local or designated USCIS Application Support
Center (ASC) and the date and time of your appointment, or, if you are currently overseas, instruct you to contact a U.S.
Embassy, U.S. Consulate, or USCIS office outside the United States to set up an appointment.
If you are required to provide biometrics, at your appointment you must sign an oath reaffirming that:
1. You provided or authorized all information in the application;
2. You reviewed and understood all of the information contained in, and submitted with, your application; and
3. All of this information was complete, true, and correct at the time of filing.
If you are a U.S. citizen filing this form on behalf of a child under the age of 14, you may provide your signature at the
ASC, instead of your child signing for themselves.
Copies. You should submit legible photocopies of documents requested, unless the Instructions specifically state that you
must submit an original document. USCIS may request an original document at the time of filing or at any time during
processing of an application or petition. If USCIS requests an original document from you, it will be returned to you after
USCIS determines it no longer needs your original.
NOTE: If you submit original documents when not required or requested by USCIS, your original documents may be
immediately destroyed after we receive them.

9. Proof of Status as U.S. National (only required if you are claiming U.S. citizenship as described below).
If you were born outside the United States or its outlying possessions, you are born a U.S. citizen if your parents met
the following conditions:
A. Your U.S. citizen parent was physically present in the United States or one of its outlying possessions for a
continuous period of one year prior to your birth; and
B. Your other parent was a national, but not a U.S. citizen.
NOTE: If you have a U.S. citizen parent and a noncitizen parent who is not a national, your U.S. citizen parent
must have met the physical presence requirements prior to your birth.
10. Proof of Legitimation (only required if you who were born out-of-wedlock and your father is your U.S. citizen
parent).
For information regarding legitimation see the USCIS Policy Manual at
www.uscis.gov/policymanual/HTML/PolicyManual-Volume12-PartH.html.
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.
11. Proof of Legal and Physical Custody. Proof of legal custody is only required for applicants whose U.S. citizen
parents divorced or legally separated and for applicants who are adopted or legitimated. Proof of legal and physical
custody is generally not required for applicants claiming U.S. citizenship at birth. In general, for adopted children, an
adoption order is sufficient for legal custody.
12. Copy of Your Permanent Resident Card or Other Evidence of Permanent Resident Status (only required if you
are claiming U.S. citizenship after birth through a U.S. citizen parent).
13. Proof of Your U.S. Citizen Parent’s Required Residence or Physical Presence In the United States (only required
if you are claiming U.S. citizenship at birth through a U.S. citizen parent). Any document that proves the U.S. citizen
parent’s residence or physical presence in the United States prior to your birth. This proof may include, but is not
limited to the following:
A. School, employment, or military records;
B. Deeds, mortgages, or leases showing residence;
C. Attestations by churches, unions, or other organizations;
D. U.S. Social Security quarterly reports; and
E. Affidavits of third parties having knowledge of the residence and physical presence.
14. Copy of Full, Final Adoption Decree (only required for adopted applicants).
15. Re-adoption or Recognition of Adoption in the United States. If you had to be re-adopted in the United States
because your foreign adoption was not full, final and complete, submit your U.S. state adoption decree. If your U.S.
state of residence recognizes your foreign adoption decree as full and final, submit evidence establishing this under
State law together with your foreign adoption decree.

What If a Document Is Unavailable?
You must provide a typed or printed explanation of the reasons a required document is unavailable and submit secondary
evidence to establish eligibility. Secondary evidence must overcome the unavailability of the required documents. USCIS
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.
The following types of secondary evidence may be submitted to establish eligibility.
1. Baptismal Certificate. Certificate under the church seal where your baptism occurred showing your:
A. Place of birth;
B. Date of birth;
C. Baptism date;
D. Parents’ names; and
E. Godparents’ names, if known.
2. School Record. An official letter from school authorities for the school attended (preferably the first school) showing
your:
A. Date of admission to the school;
B. Place of birth;
C. Date of birth or age at that time; and
D. The names and residences of your birth parents, if shown in the school records.
3. Census Records. State or Federal census records showing your:
A. Name;
B. Place of birth; and
C. Date of birth or age.
4. Affidavits (if demonstrated that other types of secondary evidence are not available).
Typed or printed statements sworn to or affirmed by two people who have personal knowledge of the claimed event.
Affidavits may overcome the unavailability of both required documents and secondary evidence. Examples of events
you may submit an affidavit for include the following:
A. Your place and date of birth;
B. Marriage; or
C. Death.
The people making these statements are not required to be U.S. citizens and may be relatives. Each affidavit must
contain the following information about the person making the affidavit:
A. Full legal name;
B. Address;
C. Place of birth;
D. Date of birth;
E. Relationship to you; and
F. Detailed information about the event to include how they came to know about its occurrence.

What Is the Filing Fee?
The fee for filing Form N-600 is $1,170.
NOTE: There is no filing fee for Form N-600 if you are a member or veteran of any branch of the U.S. Armed Forces
filing on your own behalf. You must attach proof of U.S. military service; otherwise USCIS will charge a filing fee to file
the Form N-600. Children of members or veterans of the Armed Forces are required to pay the filing fee for Form N-600.
NOTE: The filing fee is not refundable, regardless of any action USCIS takes on this application. DO NOT MAIL
CASH. You must submit all fees in the exact amounts.
Payments by Checks or Money Orders
Use the following guidelines when you prepare your checks or money orders for the Form N-600 filing fee:
1. The checks or money orders must be drawn on a bank or other financial institution located in the United States and
must be payable in U.S. currency; and
2. Make the checks or money orders payable to U.S. Department of Homeland Security.
NOTE: Spell out U.S. Department of Homeland Security; do not use the initials “USDHS” or “DHS.” If you live
outside the United States, contact the nearest U.S. Embassy or U.S. Consulate for instructions on the method of
payment.
If USCIS rejects your Form N-600 for any of the reasons above, the application and any filing fees will be returned
to you if you provided a complete and valid mailing address.
Notice To Those Paying by Check. If you send USCIS a check, we will convert it into an electronic funds transfer
(EFT). This means we will copy your check and use the account information on it to electronically debit your account
for the amount of the check. The debit from your account will usually take 24 hours and your bank will show it on your
regular account statement.
You will not receive your original check back. We will destroy your original check, but will keep a copy of it. If USCIS
cannot process the EFT for technical reasons, you authorize us to process the copy in place of your original check. If your
check is returned as unpayable, USCIS will re-submit the payment to the financial institution one time. If the check is
returned as unpayable a second time, we will reject your application and charge you a returned check fee.
Payments by Credit Card
If you are filing your application at a USCIS Lockbox facility, you can pay your filing fee using a credit card. Please see
Form G-1450, Authorization for Credit Card Transactions, at www.uscis.gov/G-1450 for more information.
NOTE: By completing this transaction, you agree that you have paid for a government service and that the filing fee,
and all related financial transactions are final and not refundable, regardless of any action USCIS takes on an application,
petition, or request, or how long USCIS takes to reach a decision. DO NOT MAIL CASH. You must submit all fees in
the exact amounts.

Processing Information
Initial Processing. Once USCIS accepts your application, we will check it for completeness. If you do not completely
fill out this application, you will not establish a basis for your eligibility and USCIS may reject or deny your application.
Requests for More Information. USCIS may request that you provide more information or evidence to support your
application. We may also request that you provide the originals of any copies you submit. If we request an original
document from you, it will be returned to you after USCIS determines it no longer needs your original.
Requests for Interview. We may request that you appear at a USCIS office for an interview based on your application.
At the time of any interview or other appearance at a USCIS office, we may require that you provide your biometrics to
verify your identity and/or update background and security checks.
Decision. The decision on Form N-600 involves a determination of whether you have established eligibility for the
immigration benefit you are seeking. USCIS will notify you of the decision in writing.
NOTE: Any Form N-600 that is not signed or accompanied by the correct fee, except those accompanied by a fee waiver
request (Form I-912, Request for Fee Waiver), will be rejected. A Form N-600 that is not completed according to these
Instructions, is missing pages, or otherwise not executed in its entirety, or is not accompanied by the required initial
evidence may be rejected or delayed. You will be notified why the application is considered deficient. You may correct
the deficiency and refile Form N-600. An application is not considered properly filed until accepted by USCIS.
