Dual citizenship in the United States has become the norm rather than the exception, both in immigration law and in the politics of the United States of America. Dual citizenship in the United States is no longer prosecuted, and its presence does not lead to liability. Therefore, retaining foreign citizenship upon naturalization in the United States is no longer a problem. However, before applying for US citizenship, an applicant who wishes to retain the citizenship of their home country must clarify whether they can retain the citizenship of their home country by adopting an American one.
The commission by a US citizen of such a crime as treason against the United States of America and an attempt to overthrow the US government by force can also lead to the termination of American citizenship. Any conspiracy or attempts at conspiracy, any action to take up arms and send them against the United States, including in a war on the side of another state, can lead to the forced deprivation of American citizenship.
Termination of American citizenship is possible not only by force, but also voluntarily. Voluntary termination of citizenship requires the submission of an appropriate application, which is signed by a US citizen in the presence of a US diplomatic or consular officer. Subsequently, the US Department of State will issue a special Certificate of Revocation and revoke the US citizen's passport. Voluntary renunciation of American citizenship is an irreversible process, with all the ensuing consequences. Thus, for example, entry into the United States of America will be subject to US law in relation to foreigners, US citizenship will not be able to be transferred to children, except for the cases of their birth in the territory of America, and parents who have lost US citizenship will not be able to process the termination of US citizenship for their minor children.
