One can become a U.S. Citizen through a variety of means—birth in the United States, birth abroad to a U.S. citizen parent, or through the naturalization process. For all of these, a specific series of legal requirements must be met. At the U.S. Embassy in Lisbon, Portugal we can provide certification of U.S. citizenship for eligible individuals born abroad to U.S. citizen parents. Our US Embassy in Lisbon, Portugal also processes Certificates of Loss of Nationality for those U.S. citizens who would like to give up their U.S. citizenship or believe that they have expatriated themselves.

Consular Report of Birth Abroad (under age 18)
As a U.S. citizen parent(s), you should report your child’s birth abroad as soon as possible to the nearest U.S. Embassy to establish an official record of the child’s claim to or acquisition of U.S. citizenship at birth. The official record will be the Consular Report of Birth Abroad (CRBA), Form FS-240. This form is evidence of U.S. citizenship, issued to a child born abroad to a U.S. citizen parent or parents who meet the requirements for transmitting citizenship under the Immigration and Nationality Act (INA). CRBA applications must be made before the child’s 18th birthday.

Child Citizenship Act of 2000
The Child Citizenship Act of 2000 allows certain foreign-born, biological and adopted children of American citizens to acquire American citizenship automatically. These children did not acquire American citizenship at birth, but they are granted citizenship when they enter the United States as lawful permanent residents (LPRs).
WHAT IS THE EFFECTIVE DATE OF THE CHILD CITIZENSHIP ACT ?
The effective date of the Child Citizenship Act is February 27, 2001. Children who met these requirements on that date automatically became American citizens. Children who were 18 years of age or older on that date did not acquire American citizenship from the Child Citizenship Act of 2000.
WHAT ARE THE REQUIREMENTS OF THE CHILD CITIZENSHIP ACT OF 2000?
The child must meet the following requirements:
- Have at least one American citizen parent by birth or naturalization;
- Be under 18 years of age;
- Live in the legal and physical custody of the American citizen parent; and
- Be admitted as an immigrant for lawful permanent residence.
In addition, if the child is adopted, the adoption must be full and final.
WHAT ARE THE OTHER PROVISIONS OF THE CHILD CITIZENSHIP ACT?
Another section of the Child Citizenship Act provides that children (biological or adopted) of American citizens who are born and reside abroad, and who do not become American citizens at birth can apply to the Bureau of Citizenship and Immigration Services in the Department of Homeland Security (USCIS) for a certificate of citizenship if the following conditions are met.
- At least one parent of the child is an American citizen by birth or naturalization.
- The American citizen parent has been physically present in the United States for a total of at least five years, at least two of which are after the age of 14. If the child’s American citizen parent cannot meet the physical presence requirement, it is enough if one of the child’s American citizen grandparents can meet it.
- The child is under the age of eighteen.
- The child lives abroad in the legal and physical custody of the American citizen parent and has been lawfully admitted into the United States as a nonimmigrant.
Children who acquire citizenship under this new provision do not acquire citizenship automatically. They must apply to the Bureau of Citizenship and Immigration Services in the Department of Homeland Security (USCIS) and go through the naturalization process.
IF THE U.S. CITIZEN PARENT IS LIVING ABROAD AND DID NOT LIVE IN THE UNITED STATES FOR THE REQUIRED PERIOD OF TIME, HOW CAN A FOREIGN-BORN CHILD BECOME A U.S. CITIZEN?
If the parent and child are residing abroad and the U.S. parent did not live in the USA for the required period of time, the child may be eligible for “expeditious naturalization” if the child’s U.S. citizen grandparent was physically present in the United States for a period totaling five years, and at least two years after the age of 14. The grandparent can be living or deceased at the time of the application. If deceased, the grandparent must have been a citizen prior to the child’s birth and at the time of the grandparent’s death. You must file an application with a USCIS field office in the United States. The USCIS will determine whether your child is eligible. If the child is eligible, the USCIS will approve the application and forward you a letter and naturalization appointment date. You can present the USCIS approval and appointment letter to the U.S. embassy or consulate where you are living. The U.S. embassy or consulate will issue the child a B‑2 visitor visa. This process allows parents to visit the United States to naturalize their child as a U.S. citizen.
HOW DOES THE CHILD GET A PASSPORT UNDER THE CHILD CITIZENSHP ACT?
You will need the following when the child applies for a passport:
- Proof of the child’s relationship to the American citizen parent. For the biological child of the American citizen this will be a certified copy of the foreign birth certificate (and translation if not in English). For an adopted child, it is a certified copy of the final adoption decree (and translation if not in English);
- The child’s foreign passport showing the Bureau of Citizenship and Immigration Services in the Department of Homeland Security (USCIS) I-551 stamp in the passport, or the child’s permanent resident card (green card);
- Proof of identity of the American citizen parent(s)
- Passport application, passport photographs and fees.
Renunciations & Relinquishments
To renounce U.S. citizenship, you must perform a series of actions voluntarily and with intent to relinquish U.S. citizenship. The basic nature and elements of a renunciation are outlined here at travel.state.gov/.
U.S. citizens cannot effectively renounce their citizenship by mail, through an agent, or while in the United States because of the provisions of section 349(a)(5) of the Immigration and Nationality Act. All renunciations and other recognitions of loss of nationality for U.S. citizens in Portugal are processed at the U.S. Embassy in Lisbon, Portugal.
