What is Dual Citizenship?

Dual citizenship – formally known as dual nationality – means that a person is a citizen of two countries at the same time.

In the United States, there’s no law that mentions dual nationality, and its citizens are not required to choose just one nationality. But what about other countries?

Do all countries allow dual citizenship, and what are the rules about calling two nations “home”?

Guide to Dual Citizenship in the USA

Dual Citizenship in Texas - Davis & Associates

As a U.S. citizen, you’re not prohibited from holding citizenship in another country. If you’re a naturalized citizen, there’s no requirement for you to renounce your citizenship from your home country, either – at least, not as far as the United States is concerned. Some countries forbid their citizens from holding dual citizenship.

What Countries Allow Dual Citizenship?

If you’re pursuing United States citizenship, you need to be aware that your home country may not allow you to keep your citizenship once you attain it in the U.S. That means you will lose your passport from your home country while gaining an American passport; you could lose your right to vote in your home country; you may no longer qualify for national programs in your home country, such as healthcare; and you may lose other rights, as well.

If you’re not sure whether your home country allows dual citizenship, consult the table below and speak to a Dallas or Houston immigration attorney about your situation. If your country is not represented here, your attorney can point you in the right direction.

What About the U.S.’s Oath of Allegiance?

Dual Citizenship Immigration Services - Davis & AssociatesThe United States’ Oath of Allegiance requires you to say that you “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,” but that doesn’t explicitly address dual citizenship in the USA. In fact, the U.S. Supreme Court ruled in Kawakita v. United States that “a person may have and exercise rights of nationality in two countries and be subject to the responsibilities of both.”

What is the U.S. Naturalization Timeline Like?

Dual Citizenship Attorneys- Davis & AssociatesIn order to become a naturalized citizen of the United States, you must first become a lawful permanent resident. Usually, you must remain a lawful permanent resident for three to five years. Lawful permanent residents – commonly called green card holders – can apply for naturalization as soon as they have met the requirements. From that time, it can take a little over a year (and longer, in some cases) to become a naturalized U.S. citizen.
