Another false narrative Obama supporters have successfully implemented is that natural born citizenship status is held in perpetuity; i.e., once born in the United States, then you are forever eligible to be POTUS.

Unless you somehow lose your natural born citizenship status, you are.

If you renounce your natural born US citizenship, then you aren't.

Again, whether another country considers you to be a natural born citizen of their country is irrelevant. Contrary to the armchair theorists there's no rule requiring exclusive citizenship. There can't be. If that were the case, then Iran could make all possible candidates ineligible by declaring all Americans to be citizens of Iran.

In which case, our law would give countries like Iran the power to prevent us from legally electing another President.

"If you renounce your natural born US citizenship, then you aren't."

Only the Sec. of State can renounce a U.S. citizens' citizenship. An oath of renunciation submitted by a U.S. citizen who has moved out of the U.S. is merely a request for the SoS to renounce the applicant's U.S. citizenship. Citizenship is not renounced until a Certificate of Loss of Nationality is signed by the SoS.

Occasionally, the SoS issues a CLN as soon as the ex-pat meets the minimum requirements for a CLN to be issued. Sometimes the SoS issues a CLN when the ex-pat is deemed to have requested a CLN by their actions while living abroad. Sometimes the SoS refuses to issue a CLN even though the ex-pat has met all the requirements for a CLN to be issued and they must sue in Federal Court for a writ of mandamus.

It is only reasonable to assume a CLN wasn't issued to a U.S. Citizen if they can prove they have never lived outside of the United States.
