There are several things you could do to lose your citizenship in the United States.
You can’t serve in another country’s army, be convicted of treason, or vote in another country’s election.
You also lose your citizenship if you formally renounce it.
American citizenship can also be restored in some cases.
American law permits multiple citizenship, which means a citizen of the United States can be a citizen of another country at the same time.
Benefits of United States citizenship include consular protection outside the United States, access to social services, and protection from deportation.
