Renunciation of Citizenship
A US citizen always has the option of voluntarily relinquishing US citizenship by formally renouncing his or her citizenship status before a diplomatic or consular officer in a foreign state.
A person wishing to renounce US citizenship must appear in person before such a US official, in a foreign country—normally at a US embassy or consulate—and sign an Oath of Renunciation.
Thus, US citizens cannot renounce citizenship while in the US (except in time of war), nor can parents renounce citizenship on behalf of their minor children.
A US citizen under the age of 18 must convince a diplomatic or consular officer that he or she understands fully the nature and consequences of the oath of renunciation and is voluntarily seeking to renounce his or her US citizenship.
*** If a US citizen child is under the age of 14, US common law requires that the child’s understanding be established by substantial evidence. ***
The US Department of State has determined that there can be no intent to relinquish US citizenship if the renunciant intends to continue to reside in the US unless the renunciant demonstrates that any residence will be as an alien properly documented under US immigration laws.
Renunciation of US citizenship is irrevocable and cannot be set aside without administrative or judicial appeal, except in the case of a former US citizen who officially renounced his or her citizenship prior to attaining the age of 18.
*** Such a renunciant can have citizenship reinstated if he or she makes known that desire to the Department of State within six months of attaining the age of 18.***
When a determination of loss of citizenship has been approved by the Department of State, the Department issues a Certificate of Loss of Nationality (‘CLN’) which is sent to the former US citizen, together with that person’s cancelled US passport.
The CLN will state that citizenship was lost at the time of renunciation or when another expatriating act was performed with the intention to relinquish US citizenship.
When a former US citizen has expatriated, that person will be subject to the immigration laws of the US the same as any other alien, including being subject to all of the grounds of ineligibility for visas and inadmissibility to the US.
Then there’s always the possibility that what Obama doesn’t wish us to see wouldn’t necessarily make him ineligible.
But it might be hugely embarrassing or worse an impeachable offense.
Like more than one Social Security number.
What’s that all about?!
Just speculating.
