Is Japan any different from the USA in that respect?
From what I've heard it goes like this: British person applies for US citizenship. He has to "renounce" his British citizenship and hand over his British passport to the US authorities, who shred it. The next day he goes to the British embassy, tells them what has happened and asks for a new passport. The British authorities give him a new passport and, of course, they don't say anything to the US authorities.
(There might be different cases to consider here, depending on how you acquired your British citizenship. As I understand it, if you were born in the UK of British parents then you have a right to a British passport regardless of how old you are, where you have lived, and what other passports you've had. It's not possible to "renounce" that right. It might be different for someone who acquired British citizenship in some other way: perhaps some people could "renounce" their citizenship.)
>U.S. law does not mention dual nationality or require a person to choose one nationality or another. A U.S. citizen may naturalize in a foreign state without any risk to his or her U.S. citizenship
Thanks for the correction! What I'd heard on several occasions in face-to-face conversation seems to be inaccurate. I wonder where the inaccurate story came from: a different country, a long time ago, or totally made up?
