As a cross-border immigration lawyer based in Windsor, Ontario, Christina Loebach helps individuals and families navigate citizenship and immigration matters in both Canada and the United States. A common query from clients born outside the U.S. to an American parent is whether they are already U.S. citizens and how to formally claim their citizenship status.

Acquisition of U.S. Citizenship at Birth

Under U.S. immigration law, a child born abroad to at least one U.S. citizen parent may automatically acquire U.S. citizenship at birth by operation of law. Unlike naturalization, which grants citizenship effective from the approval date, acquiring citizenship by descent means the individual has legally held U.S. citizenship since birth.

To qualify for automatic acquisition at birth, specific statutory requirements under the Immigration and Nationality Act (INA) must be met based on the laws in effect at the time of the child's birth:

• At least one parent was a U.S. citizen at the time of the child's birth;

• A recognized legal parental relationship exists between the child and the U.S. citizen parent; and

• The U.S. citizen parent satisfied specific physical presence requirements in the United States prior to the child’s birth.
