If an event has occurred, which could result in the claimant's loss of U.S. citizenship
and such loss would be material to the claim, follow the procedure indicated below.
NOTE: Each country establishes criteria for citizenship independently; therefore, it is
possible for a country to officially recognize a claimant as a citizen of the U.S.
and another country at the same time. A person does not automatically lose their U.S.
citizenship if the country considers them a citizen of another country.
If a person alleges dual citizenship or alleges U.S. citizenship but submits evidence
to the contrary, such as a subsequently issued citizenship document from another country
(i.e., a U.S. birth certificate and a foreign passport), ask that person to explain
their citizenship status.
Depending on the response, take one of the following actions.
1. Law of return or retention for citizenship at birth
If the claimant alleges they obtained dual citizenship by the law of return or retention
of citizenship at birth, accept the allegation if there is no conflicting evidence.
For examples of these dual entitlement situations, refer to RS 02640.001.
If the claimant obtained dual citizenship by naturalization in another country, ask
them to submit evidence to establish continuing U.S. citizenship. We accept the following
as evidence.
-
a.
U.S. passport or any other document listed in GN 00303.300, issued later than the
foreign document.
-
b.
Determination of citizenship from the Department of State, for persons residing outside
the U.S.; or United States Citizenship and Immigration Service (USCIS), for persons
residing in the U.S.
