A child will obtain citizenship if:
- At least one parent resides in the United States or its territories before the child’s birth.
- At least one parent has a genetic or gestational connection to the child.
- Both parents in the marriage show a parental relationship to the child. Examples of this relationship include: medical, tax, educational, or other documents that show the individual has acted in a parental role.
Requirements for a child born in wedlock to a U.S. citizen parent and a parent who is not a U.S. citizen vary by birth year:
- The U.S. citizen parent was physically present in the United States or its territories for five years before the child’s birth. [cite: 11]
- At least two of these years must be after age 14.
- The U.S. citizen parent was physically present in the United States or its territories for 10 years before the child’s birth.
- At least five of these years must be after age 14.

- The father agreed in writing (unless deceased) to provide financial support for the child until the age of 18.
