Once you recieve U.S. citizenship, is your citizenship from the country you're born revoked?

Leidy is right. Some countries allow dual citizenship, some do not. The US does, by the way. And it has no rule about having to decide when you turn 18: Korea has such a rule, but not the US.

Here is a web site that has some nice information about multiple citizenships, especially which countries allow it and which do not:

And here is the official information about losing US citizenship: as you can see, you have to MEAN to lose it in order to do so:

Technically there is no such thing as dual citizenship, at least with regard to the US laws. You are either a US citizen or you are not.

Now you may also be recognized as a citizen within another country. Some countries (for example Ireland & the US) automatically recognize you as a citizen if you were born there. You could potentially apply and get a passport for this country where you are also considered a citizen.

Again, this does not mean from the US perspective that you have dual citizenship. From the US perspective you are a citizen of the US only, so if you did apply for a second passport for another country that recognizes your citizenship you would not want to be displaying these when entering the US, or things could get very complicated for you.

One other thing. Some people say that applying for a passport or accepting the citizenship of another country automatically renounces your US citizenship. This is not true. You do not give up your US citizenship unless you actively request to renounce it, ie sending a letter to the US Consolate asking to renounce your citizenship.

Hope this helps.

As far as the U.S. government is concerned, you're either a U.S. citizen or a citizen of another country, so once you become a U.S. citizen you supposedly renounce your citizenship to the other country. That being said, however, my mother was born in Canada and is now a U.S. citizen, but the Canadian Crown recognizes her as having dual-citizenship status. So you can have dual-citizenship; it just depends on which country you were a citizen of before applying for U.S. citizenship.

The US will recognize dual citizenship until your have reached 18 years of age, then you need to choose. If your an American Citizen, then that is your only citizenship, but your orginal country could recognize dual citizenship at any age, then your OK. Use your American as you prrimary and use your other as it suits your needs.

I believe it depends on the country of birth, for example Argentina does not recognize US citizenship so when I travel there I have to have 2 passports one to leave the US, another to enter Argentina, I have to report my entrance in person to the American embassy in BS.AS. and of course do the whole process over when leaving... I guess it is not as convenient but... I don`t mind...I really did not want to become a citizen, but it was a requisite in the state I reside to have a permanent Teaching Cert.

depends on the two countries -- if they allow it or not both ways.

if you are a us citizen to begin with and if you marry someone from another country that ALLOWS dual citizenship -- then you are dual. vice versa.

however, if you are a us citizen and if you PLED ALLEGIANCE to another country or... read the front section in your passport... then you could be at risk of losing your us citizenship. AND you should since you are guilty of treason.

The US does not recognize your citizenship of other countries if you are a US citizen, but it has no bearing on whether the other country claims you as a citizen.

It depends on your home coutry's laws. Some country's only alllow you to have one citizenship, so then yes would be the answer. But the US like colombia and most other coutrie allow you to have to or more. so you need to check out you native country's laws.

i'm 22, and a dual citizen of the US (i was born here in california) and France (father born and raised in France).
