N-600, Application for Certificate of Citizenship Frequently Asked Questions

What is Form N-600, Application for Certificate of Citizenship?

Form N-600, Application for Certificate of Citizenship, is filed to obtain a Certificate of Citizenship which serves as evidence of your or your child’s U.S. citizenship. You may file Form N-600 if you were born abroad and are claiming U.S. citizenship at birth through your parents. You may also file Form N-600 to obtain evidence of citizenship if you automatically became a U.S. citizen by operation of law after your birth but before you turned 18 years of age. A parent or guardian may also file Form N-600 on behalf of a minor child.

Please note that USCIS does not issue Certificates of Citizenship in cases where the person became a U.S. citizen based on birth in the United States. USCIS only issues Certificates of Citizenship to those individuals who were born abroad but are U.S. citizens at birth through their parents, or who became citizens after birth but before the age of 18.

General Questions

My U.S. citizen parent(s) is deceased. Does this affect my ability to apply for a Certificate of Citizenship?

No. Your parent’s death does not affect your ability to apply for a Certificate of Citizenship if you automatically acquired citizenship, either at birth or after birth, before your parent’s death. However, if you did not automatically acquire citizenship before your parent’s death, your parent’s death may affect your ability to apply for a Certificate of Citizenship unless you meet the requirements of section 322 of the Immigration Nationality Act (INA). Please note that section 322 of the INA does not provide for automatic citizenship, but it does allow for naturalization before the age of 18 and allows you to rely on your grandparent’s physical presence instead of your parent’s physical presence.

I am claiming citizenship through my mother. My parents were not married at the time of my birth. Does this affect whether I automatically acquired citizenship?

It may. You acquired U.S. citizenship at the time of your birth if you were born out of wedlock after Dec. 23, 1952 and your U.S. citizen mother was physically present in the United States or its outlying possessions for at least one year prior to your birth. The requirements before Dec. 23, 1952 varied to some extent. If you have specific questions before that time period, please contact the USCIS Contact Center at 800-375-5283. For people who are deaf, hard of hearing or have a speech disability: TTY 800-767-1833.

If you are claiming U.S. citizenship after birth, your birth out of wedlock may affect your ability to acquire citizenship through your mother depending on when you turned 18 years of age.

I am a U.S. citizen who gave birth to a child abroad using a donated egg and sperm. Is my child a citizen?

Maybe. If you are recognized by the relevant jurisdiction as the legal mother at the time of birth under the law of the relevant jurisdiction and you meet all the other requirements (such as the required years of U.S. residence), non-genetic gestational mothers may transmit citizenship to their children.

I am claiming U.S. citizenship through my father. My parents were not married at the time of my birth. Does this affect whether I automatically acquired citizenship?
