What part "I hereby declare, on oath, that I absolutely and entirely renounce and abjure all allegiance and fidelity to any foreign prince, potentate, state, or sovereignty of whom or which I have heretofore been a subject or citizen;" do you not get?
The US is not cool with dual citizenship, the US Courts starting in the 60's will not allow US laws against it to be enforced. In Trumps' mom day dual citizenship was illegal. Once again liberal courts are the problem. And who gives a flip what the UK thinks? Trumps' mother renounced her UK citizenship and I will bet dollars to donuts that she traveled on a US passport not a UK passport after taking her oath of citizenship.
Thank you, Lord Chancellor. I am sorry for quoting the U.K. law on the matter when clearly written U.K. law means nothing compared to your opinion.
