First, let’s determine if you are eligible to file Form N-600.

On this page, CitizenPath will ask you several questions to help make sure that you meet the requirements of U.S. citizenship. You will only be able to finish this application if we believe you meet the requirements to file Form N-600, Application for Certificate of Citizenship, and claim your U.S. citizenship.  Explain more >>

Indicate if the applicant is a minor or adult.
  • For Your Information: You may file this application if you are the U.S. citizen parent or legal guardian who has legal and physical custody of an adopted or biological child (under 18 years of age). Answer the questions in this application from the perspective of the child who is applying for a Certificate of Citizenship.

Indicate if your permanent home is in the United States.

Do not file this application if you have already received a decision on a previously filed Form N-600.  Explain more >>
  • We found a problem. Based on your answer, you cannot continue.  You may not be eligible to file Form N-600. We recommend that you speak to an immigration attorney for more information about your specific situation.


  • Your answer to this question suggests that you have a history which may require the assistance of a legal professional. We want the best result for you, and therefore CitizenPath suggests that you consult with an experienced immigration attorney that can provide you with additional guidance and representation.
  • For Your Information: Your U.S. passport is generally sufficient proof of your U.S. citizenship. A Certificate of Citizenship never expires and is a good back up document. You may proceed if you would also like to obtain a Certificate of Citizenship.

Indicate if you have ever intentionally or unintentionally abandoned status as a U.S. permanent resident. If you have never been a permanent resident, answer "No."
  • Although you may be eligible to file Form N-600, your situation is complex. Therefore, we recommend that you consult with an experienced immigration attorney instead of using our service.


  • We found a problem. Based on your answer, you cannot continue.  Currently there is not a provision in the law that allows step children to acquire U.S. citizenship through his or her parents. You must be the biological or legally adopted child of a U.S. citizen parent to file N-600. Please consult with an immigration attorney for more information about your specific situation.
  • Although you may be eligible to file Form N-600, your situation is complex. Therefore, we recommend that you consult with an experienced immigration attorney instead of using our service.

If your parent was a U.S. citizen at the time of his/her death, you may also indicate your parent is a U.S. citizen.


Indicate if the date your mother became a citizen is before your birth date.

Important: Indicate if you have an original document or copy of a document that proves your mother is a U.S. citizen.  Explain more >>


Indicate if the date your father became a citizen is before your birth date.

Important: Indicate if you have an original document or copy of a document that proves your father is a U.S. citizen.  Explain more >>
  • Although you may be eligible to file Form N-600, your situation is complex. Proof of your parent's U.S. citizenship is essential to your N-600 application. The burden of proof is on the applicant. Therefore, we recommend that you consult with an experienced immigration attorney instead of using our service.

Indicate if your biological parents were already married at the time of your birth.

  • Although you may be eligible to file Form N-600, your situation is complex. In the case of a child who is born out of wedlock, the child must have been legitimated by the U.S. citizen father under the law. The specific legal requirements can vary significantly based on year of birth and jurisdiction. Therefore, we recommend that you consult with an experienced immigration attorney instead of using our service.

It is possible that you may have a claim to U.S. citizenship through your mother and father. We recommend you select the parent that you have the best documentation to support your application. USCIS will not do the research for you. The burden of proof is on you to provide clear evidence that at least one parent is a U.S. citizen. You'll need to provide a copy of at least one of the following documents to evidence your parent's U.S. citizenship:

  • Birth certificate showing birth in the U.S.;
  • Certificate of Naturalization;
  • Certificate of Citizenship;
  • Report of Birth Abroad to U.S. Citizen; or
  • U.S. passport

Consider the quality of the evidence that you have for each parent and select one parent below. If you have identical evidence for each parent, we suggest you select your mother.


Select the parent for whom you have the best evidence of U.S. citizenship.
Becoming a U.S. Citizen at Birth (Acquisition)

Initially, we will ask you a series of questions to determine if you have a claim to U.S. citizenship at birth. If you don't have a path to citizenship at birth, we'll determine if you became a U.S. citizen through a parent after birth.
 


Laws regarding acquisition of citizenship have changed over the years. Carefully select the period that you were born.
  • Although you may be eligible to file Form N-600, your situation is complex. Therefore, we recommend that you consult with an experienced immigration attorney instead of using our service.

Indicate if your mother lived in the U.S. or its outlying possessions for any period before you were born.

Indicate if your mother was in the U.S. or its outlying possessions for at least 5 years before you were born.

Indicate if your mother was in the U.S. or its outlying possessions for at least 2 years after she turned age 14.

Indicate if your mother was in the U.S. or its outlying possessions for at least 10 years before you were born.

Becoming a U.S. Citizen after Birth (Derivation)

Now we will ask you a series of questions to determine if you have a claim to U.S. citizenship after birth. 
 


Laws regarding derivation of citizenship have changed over the years. Carefully select the period that you were born.
  • Although you may be eligible to file Form N-600, your situation is complex. Therefore, we recommend that you consult with an experienced immigration attorney instead of using our service.

Indicate if you were granted green card status before your 18th birthday.

Indicate if you lived with your U.S. citizen mother (for any period as a permanent resident) while you were under the age of 18.

Indicate if you lived with your U.S. citizen father (for any period as a permanent resident) while you were under the age of 18.

  • We found a problem. Based on your answer, you cannot continue.  It does not appear that you meet the requirements to apply for a Certificate of Citizenship. Citizenship laws are extremely complex and have changed many times over the years. For the most thorough analysis of your specific situation, we encourage you to contact an immigration attorney.
