How to get American citizenship back, once it is renounced?
<p>American citizens can have dual citizenship, but if an American citizen who has renounced his or her citizenship (even though the person was originally an American citizen), then what is a way of obtaining it again? Can an American citizen without dual citizenship (only an American citizen), renounce his or her citizenship?</p>

<p>Possibly, by the same means that a non-citizen could be naturalized. But, immigration and nationality officials have broad discretion and would probably refuse to grant citizenship to someone who had previously renounced it.</p>

<p>Yes. For example, Prince Harry's financee plans to renounce her U.S. citizenship and contemporaneously be granted U.K. citizenship (the paperwork goes through really easily when the Queen is your grandmother in law). Renunciation of citizenship is not necessarily tied to gaining a new citizenship, but leaving yourself stateless would be a foolish thing to do.</p>
