It is possible if you wanted to keep U.S. citizenship status at the time you got a foreign country’s citizenship. The State Department’s guidelines for determining intent to keep U.S. citizenship are applicable retroactively to past cases. To initiate such a case you should contact a U.S. embassy or consulate or write to the State Department Office of American Citizens Services.
It will probably be possible to ask the State Department to reinstate your U.S. citizenship status. if you told the State Department that you intended to keep it when getting a foreign citizenship and they revoked your U.S. citizenship status anyway and the other country didn’t require you to sign or swear away your U.S. citizenship. Another situation when you might get it reinstated is if you asked a U.S. consulate if dual citizenship was possible and you were told it was not, but you still went ahead because you felt you needed to get that other citizenship.
U.S. Citizenship is actually pretty difficult to lose. Aside from declaring your allegiance or citizenship to a foreign country, the only other ways you can lose U.S. citizenship is if you:
- Served in a “policy level position” in a foreign government;
- Committed treason, such as by fighting in a war against the U.S. voluntarily;
- Formally renounce U.S. citizenship at a U.S. Embassy or to the U.S. Attorney General;
- Acted in a manner considered totally inconsistent with any possible intent to keep a U.S. citizenship; and/or
- Run for public office in a foreign country (under certain conditions)
Renouncing your U.S citizenship means that you are giving up your U.S. citizenship. Renouncing your U.S. citizenship means:
- Give up your rights and responsibilities as a U.S citizen;
- Required to obtain a visa when visiting the U.S.; and
- You must become a citizen of another nation or risk being “Stateless”.
If you did give a renunciatory declaration in a foreign naturalization oath it might still be ok. The State Department is nowadays pretty relaxed about such declarations and it might be ok if you took it because you needed a foreign citizenship and taking the renunciatory oath was the only way to do that and you had rather not made that declaration.
An experienced immigration law attorney will be able to walk you through any immigration laws that are applicable to your case. Since several government agencies may be involved in cases dealing with immigration and naturalization, it is a good idea to consult an attorney who can advise you of your best course of action in moving forward.
