Citizenship Through Parents

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.

For more information, please see our Citizenship Through Parents page.
