Transmitting U.S. Citizenship to a Child Born Abroad: CRBA Rules

A child born outside the United States acquires U.S. citizenship at birth when at least one parent is a U.S. citizen who meets the physical presence or residence rules in the Immigration and Nationality Act. Which rule applies to you when transmitting U.S. citizenship to a child born abroad depends on three things: whether one or both parents are citizens, whether the parents are married, and when the child was born. The differences are large, and a parent who assumes the easiest rule applies can end up with a child who is not a citizen at all.

When Both Parents Are U.S. Citizens

If both parents hold U.S. citizenship at the time of the birth, the requirement is minimal. Under 8 U.S.C. § 1401(c), at least one parent must have resided in the United States or one of its outlying possessions at some point before the child was born.¹ There is no minimum length of time. A year spent living in the U.S. as a teenager is enough.

“Residence” here means the parent’s actual principal dwelling, not a stated intent to settle. Old leases, school records, or utility bills in the parent’s name are the kind of proof that establishes it. For this rule, “outlying possessions” means American Samoa and Swains Island only.² Time in Guam, Puerto Rico, or the U.S. Virgin Islands counts as time in the United States itself.

When Only One Parent Is a U.S. Citizen (Married Parents)

The bar rises sharply when only one parent is a citizen. For any child born on or after November 14, 1986, 8 U.S.C. § 1401(g) requires the citizen parent to have been physically present in the United States for at least five years before the child’s birth, and at least two of those five years must have come after the parent turned 14.¹

This is the rule that catches most families off guard. A citizen parent who left the U.S. at 15 and never returned simply cannot meet it. “Physical presence” is stricter than “residence.” It means actual days on U.S. soil or in an outlying possession, not just keeping a U.S. address. A parent who lived in the U.S. for six years but spent eight cumulative months of that on international trips has closer to five years and four months of physical presence. Consular officers do the calendar math, and parents should expect to account for their time month by month.

Children Born Before November 14, 1986

The current five-year standard replaced a harder one. For children born before November 14, 1986, the citizen parent had to show ten years of physical presence, with at least five of those years after the parent turned 14.³ A citizen parent who left the U.S. at 19, for example, could not possibly have accumulated five post-14 years. Some adults born abroad in this era have discovered years later that they never acquired citizenship at birth. If the birth falls in this window, the old law governs, not the current one.

When the Parents Are Not Married

If the parents were unmarried at the time of birth, 8 U.S.C. § 1409 applies, and it treats mothers and fathers differently.

U.S. Citizen Mother

A U.S. citizen mother needs only one year of continuous physical presence in the United States before the child’s birth.⁴ The year must be unbroken; leaving the country during the qualifying period resets the clock. One continuous year is still far easier than five.

U.S. Citizen Father

A U.S. citizen father faces the full § 1401(g) physical presence requirement (five years, two after age 14) plus several additional steps under § 1409:⁴

A blood relationship between father and child established by clear and convincing evidence.
A written agreement by the father to financially support the child until age 18.
Before the child turns 18, either a written acknowledgment of paternity under oath or a court order establishing paternity.

A father in this situation needs both a legal paper trail and the same physical presence a married citizen parent would need.

Children Conceived Through Assisted Reproduction

For children born through surrogacy, egg donation, sperm donation, or other assisted reproductive technology, citizenship transmission turns on who is biologically connected to the child. The State Department adjudicates these claims based on the genetic or gestational relationship between the child and the U.S. citizen parent.⁵ An anonymous donor cannot transmit citizenship; the citizen parent must be identifiable and verifiable.

USCIS applies a broader standard. Under its policy guidance, a non-genetic, non-gestational legal parent can transmit citizenship if that parent is married to the child’s genetic or gestational parent at the time of birth and the relevant jurisdiction recognizes both as legal parents.⁶ A claim may therefore succeed through USCIS even if the State Department declines to issue a Consular Report of Birth Abroad.

Documentation in ART cases is heavier than for traditional births. Officers may request certified medical records from the fertility procedure, prenatal care records, insurance documents, and, in surrogacy cases, the legal contracts among the intended parents, the clinic, and the surrogate.⁵ DNA testing may be recommended. Plan the documentation before the child is born; assembling these records afterward is much harder.

Credit for U.S. Military and Government Service Abroad

Time a parent spent overseas in the U.S. Armed Forces or as a federal government employee counts as physical presence in the United States for purposes of the § 1401(g) five-year rule.¹ The same benefit extends to employees of certain international organizations and to qualifying dependents living in the service member’s household. A parent who spent three years in the U.S. after age 14 and then served two years at a base in Germany can count all five toward the requirement. Official service records, military orders, and government personnel files are the proof.

If the Parent Falls Short: The Grandparent Path

When a citizen parent cannot meet the five-year physical presence rule (a common problem for parents who grew up abroad), a backup exists. Under INA Section 322 (8 U.S.C. § 1433), the child can obtain citizenship if a U.S. citizen grandparent meets the same five-year/two-after-14 standard the parent could not.⁷

This is not automatic citizenship at birth. It is a separate naturalization application. The child must be under 18, unmarried, and must remain both throughout the process, including at the Oath of Allegiance. Families file Form N-600K, and USCIS recommends filing at least 90 days before the requested interview date.⁸ The child’s 18th birthday is a hard deadline; miss it and this path closes for good.

Proving Physical Presence

Physical presence is where most claims stall. On Form DS-2029, the citizen parent lists every period of U.S. presence from birth to the child’s birth, with month-and-year precision at a minimum.⁹ The strongest evidence comes from official records:

School transcripts from elementary through university, showing enrollment and attendance in the U.S.
Employment records: W-2s, pay stubs, or employer verification letters with start and end dates.
Social Security earnings statements from the SSA, showing years with reported U.S. earnings.
Federal tax returns filed from a U.S. address.
CBP travel records, available through the I-94 portal at i94.cbp.dhs.gov, showing arrival and departure history for the past ten years.

Secondary evidence such as leases, property records, utility bills, and medical files fills the gaps. The goal is a timeline with no large unexplained holes. Parents who spent only early childhood in the U.S. should dig hard for elementary school records, childhood medical files, and even church records; anything that anchors them to a U.S. address in those years helps.

Applying for the Consular Report of Birth Abroad

The Consular Report of Birth Abroad (CRBA) is the official document recognizing that the child acquired citizenship at birth. The State Department issues it only to children under 18.¹⁰ Once the child turns 18, you have to use another route to prove citizenship, such as a U.S. passport application.

Parents file Form DS-2029 and schedule an appointment at the nearest U.S. Embassy or Consulate. At least one parent and the child must appear in person. The fee is $100.¹¹ Bring:

The child’s original foreign birth certificate from the local civil authority.
Proof of the parent’s U.S. citizenship: a passport, Certificate of Naturalization, or prior CRBA.
Marriage and, if applicable, divorce records establishing the parents’ legal relationship.
The physical presence evidence, organized chronologically.

Many embassies process the CRBA and the child’s first U.S. passport at the same appointment. When applying for the passport on Form DS-11, leave the Social Security Number field blank or enter zeros; the child will not have one yet. Apply for the SSN separately after the CRBA and passport arrive.¹²

Processing times vary by post. The consular officer reviews the evidence at the appointment and may ask follow-up questions about the citizen parent’s time in the United States. If the officer finds the physical presence evidence insufficient, the application is denied, and you will need more documentation before reapplying.
