Transmission of U.S. citizenship depends on:
- At least one parent having the nationality of the United States at the time of the child’s birth;
- The existence of a blood relationship between the child and U.S. citizen parent(s);
- Documentary evidence demonstrating the U.S. citizen parent(s)’ presence in the United States prior to the child’s birth.
Examples of documentation which may be considered to demonstrate a blood relationship may include:
- The child’s birth certificate (hospital birth notifications are not acceptable).
- An original marriage certificate for the parents (if applicable).
- Pregnancy and birth records, such as dated ultrasounds containing the name of mother, laboratory test results, doctor/ultrasound/hospital receipts, pictures of the mother pregnant, pictures of mother and baby immediately following
- Hospital bills from the birth, the baby’s and mother’s hospital identification bracelets, or discharge orders.
- Lease agreements, bank statements, home utility bills, or IRS tax declaration documents showing a shared address.
- Proof of relationship between parents, such as time-stamped photos of the couple together before, during, and after the pregnancy, photos of the U.S. Citizen parent with the newborn baby, Western Union money transfer receipts, email correspondence.
- Proof the couple was together at time of conception, such as original or certified copies of passport pages showing entry and exit stamps.

- Wage and tax statements (W-2)
- Academic transcripts.
- Employment records.
- Rental receipts.
- Records of honorable U.S. military service, employment with U.S. Government or certain intergovernmental international organizations; or as a dependent, unmarried child and member of the household of a parent in such service or employment.
