Can I Become A Us Dual Citizen

Can I be a dual citizen of the US and UK?

Whether YOU can is something I don’t know.. but:if you are already a USA citizen, then you can apply for British citizenship. If you are successful, the British government will not require you to renounce your other citizenshipsif you are already a UK citizen, then the US government will require you to renounce your other citizenships if you are granted US citizenship… the British government will ignore this, and continue to renew your passport :-) However, the US authorities could deem this a violation of your oath, and strip you of your newly acquired US one.

Can I become an ambassador of the USA with a dual citizenship in the USA?

Although the U.S. *PERMITS* dual citizenship, it does *NOT RECOGNIZE* foreign citizenship. This is like Costco permits their members to also become members of Sam’s Club, but Costco does not recognize Sam’s Club membership.Since the U.S. treats a person with U.S. citizenship as *AMERICAN* only regardless of how many other citizenship he has, an American cannot serve as an ambassador to the U.S. for another government.[Edit Sep 20, 2018: Someone pointed out to me that the question is actually the other way around, ie. become a U.S. ambassador to another country. Since the U.S. does NOT recognize your foreign citizenship, you are no different than an ordinary American with only one citizenship. In theory, you should be able to serve as a U.S. ambassador. For example, though the UN is not a country, the former US ambassador to the UN, Samantha Power, is an immigrant from Ireland! In practice, it boils down to if you can pass a top security clearance and whoever gives you the job trusting you enough to defend the interest of the U.S. In other words, it will be evaluated on a case by case basis, and having dual citizenship can complicate this process. For example, I have a friend working for the State department. From what he told me, given all the Russophobia nowadays it is highly frowned upon if an employee there marries a Russian! Is it written anywhere in law that their employee cannot marry a Russian? Of course NOT! However, it will be in everyone’s mind if your loyalty to the U.S. will be compromised over time. A State department employee has to serve the best interest of the U.S. and not that of a foreign country! One of the reasons the State department rotating their employees’ overseas assignments from country to country regularly is that they do NOT want you to develop emotional attachment to a foreign country!]

I am Japanese citizen, can I become dual citizen?

Well, I have 5 tri-national kids who have had to make the choice between one of my two nationalities and my wife’s nationality (Japanese). I can tell you that there is the law and there is real life. The Japanese law says, “no” you can’t have two nationalities. But real life says “yes, you can”. How?If you were registered as a Japanese first (which it sounds like you were), then unless your parents had a reason to tell the Japanese authorities that you had another nationality, they (the authorities) wouldn’t know. So, even after you passed the magic age of choosing, 20 + 2 years leeway (so 22), if you say nothing, they do nothing.There is currently no penalty for being a dual national and not giving up the non-Japanese nationality. So why care about doing it?If you were registered as a non-Japanese first, or if your parents in a fit of madness told the Japanese authorities that you have another nationality, then you might get a letter telling you to make a choice. Again, there’s no penalty for not doing so, but I suppose it is possible that this dual-nationality fence-sitting might come back to bite you if you wanted to take a government job later, and where they vet your background. Getting scholarships and government subsidies will present you with a similar problem.The Japanese will accept someone being a dual national if they show they tried to revoke their original citizenship but their country of birth denied the request.Although there is no penalty for being a dual national, I have heard of Japanese with U.S. citizenship being denied passport renewals abroad after it became clear that they were living in the U.S. for longer than a regular Japanese would stay. In these cases, you can still finesse the situation by returning to Japan regularly to take care of family registration matters in Japan, just as if you lived here permanently. Sounds like you will need to think about this strategy.
