True, ray, I'm not a lawyer (there must be a reason why Jamaicans pronounce it liar, hmm?) Again ray according to Section 349(a)(5) of the Immigration and Nationality Act (INA) (8 U.S.C. 1481(a)(5)) is the section of law that governs the ability of a United States citizen to renounce his or her U.S. citizenship. That section of law provides for the loss of nationality by voluntarily performing the following act with the intent to relinquish his or her U.S. nationality of the Immigration and Naturalization Act "F. RENUNCIATION FOR MINOR CHILDREN
Parents cannot renounce U.S. citizenship on behalf of their minor children. Before an oath of renunciation will be administered under Section 349(a)(5) of the INA, a person under the age of eighteen must convince a U.S. diplomatic or consular officer that he/she fully understands the nature and consequences of the oath of renunciation, is not subject to duress or undue influence, and is voluntarily seeking to renounce his/her U.S. citizenship." Again this information is found at:

Additionally, the laws cover citizenship if it was renounced before age 18 (assumably by parent/guardian, since Obama returned to the US by age 10).
Section G: IRREVOCABILITY OF RENUNCIATION
Finally, those contemplating a renunciation of U.S. citizenship should understand that the act is irrevocable, except as provided in section 351 of the INA (8 U.S.C. 1483), and cannot be canceled or set aside absent successful administrative or judicial appeal. (Section 351(b) of the INA provides that an applicant who renounced his or her U.S. citizenship before the age of eighteen can have that citizenship reinstated if he or she makes that desire known to the Department of State within six months after attaining the age of eighteen. See also Title 22, Code of Federal Regulations, section 50.20).
So even if his citizenship were renounced by his mother and STEP father, he could have, if it had happened, reclaim his citizenship after attaining age 18. The law is the law, ray, check it out and stop grasping at straws!
