Dual citizenship in Ireland and the United States is convenient because you get full citizen rights in two countries, and you can visit both countries without visas.

If you are already an Irish citizen, to acquire dual citizenship in Ireland and the United States, you will have to pass the standard procedure: get a green card, move to the US, and live in the country for three or five years at least, and then apply for US citizenship. The only potential problem with getting dual citizenship for an Irish is if Ireland prohibits or restricts your right to become a rightful citizen in the United States.

Actually, Ireland is one of the countries that is very lenient towards people who get naturalized in the United States. The Irish government does not anyhow forbid you to become a bipatride (a person with dual citizenship). With regards to how the United States manage dual citizenship, you will not have to give up your Irish citizenship or nationality either.

So, what can stop you from getting US citizenship? The thing that may discourage you from getting US citizenship is an increased tax burden. As you may already know, according to the US laws, you must pay taxes to IRS (Internal Revenue Office), a US national tax agency, no matter in which country you are currently working. If you come back to Ireland for a work, IRS will fine you in case you forgot to pay taxes.

Still, there is no need to refuse getting US citizenship. In fact, Ireland and the United States have agreed on a special tax treaty aiming to decrease the tax burden on your shoulders. As a result, you have the right to get back the money that you paid as taxes in Ireland as an offset against taxes you paid in the US.

Unlike the US, Ireland will not force you to pay taxes if you do not live in the country. That is, when you move to the US and naturalize, you will have to pay only the taxes in the US. We still strongly recommend that you contact the Irish tax agency or consult a lawyer to know all the specificities about paying taxes.

And if you are going to naturalize in the United States and live in the country for a long time, you will have no issues tax-wise with Ireland.
