Citizenship Through Parents

Congress has enacted laws that determine how U.S. citizen parents convey citizenship to children born outside of the United States. Generally, you may obtain citizenship through your U.S. citizen parents when you are born, or after your birth but before you turn 18.
Eligibility
Whether you become a U.S. citizen at birth or after birth depends on a number of factors, including:
- Your date of birth;
- The citizenship and marital status of your parents;
- Your parents’ physical presence and residence in the United States before your child’s birth
- Whether you were born in or out of wedlock;
- Whether you were legitimated by the parent under the applicable laws; and
- Whether you were legally adopted.
