One of the most common questions for immigrants applying for U.S. citizenship is whether they must give up their original nationality. Fortunately, the answer for most applicants is encouraging: the United States allows dual citizenship. This means you can become a U.S. citizen without renouncing your original citizenship, as long as your country of origin also permits it.
What Does U.S. Law Say About Dual Citizenship?
The U.S. government does not require naturalized citizens to give up any prior nationality. In fact, according to the U.S. Department of State, “U.S. law does not require a person to choose one nationality or another.”
The U.S. Citizenship and Immigration Services (USCIS) also does not prohibit dual citizenship. You can review their naturalization policies here.
Legally, the U.S. Supreme Court solidified this position in the 1967 case Afroyim v. Rusk, ruling that U.S. citizenship cannot be taken away without the individual’s voluntary consent. Even though naturalized citizens recite an oath renouncing former allegiances, this statement does not invalidate other nationalities unless explicitly acted upon.
How Does Your Home Country Handle Dual Citizenship?
While the U.S. allows dual nationality, the same is not true for every other country. Some countries may automatically revoke your citizenship when you acquire another. Others may allow it but require you to formally register or notify the government.
- Countries that restrict dual citizenship include India, China, and Japan. If you become a U.S. citizen, you may lose your original nationality under these countries’ laws.
- Countries that allow dual citizenship include Mexico, Canada, Colombia, and the Philippines. However, they may require additional steps to retain your rights as a citizen.
It is always best to check directly with your country’s embassy or consulate to understand the impact of U.S. naturalization on your original citizenship status.
What Responsibilities Come With Dual Citizenship?
Being a citizen of two countries can come with added responsibilities. Here are a few important ones to consider:
1. Passport Use
U.S. law requires all citizens to use a U.S. passport when entering or leaving the country. If your other country also requires its passport for travel, you may need to carry both. The State Department provides guidance on travel for dual nationals.
2. Taxes
As a U.S. citizen, you are required to file annual tax returns on worldwide income, even if you live abroad. However, tax treaties and exclusions, like the Foreign Earned Income Exclusion, may help reduce your liability. More details are available from the IRS.
3. Military or Civic Obligations
Some countries require their citizens, regardless of residency, to complete military service, vote, or pay national taxes. As a dual citizen, you may be expected to comply with the legal requirements of both nations.
4. Limited U.S. Protection Abroad
If you are in the country of your other citizenship, that government may consider you solely its citizen. This could limit the ability of U.S. consular officials to assist you in emergencies or legal matters.
What Steps Should You Take?
-
- Contact your country’s embassy to learn about its stance on dual nationality.
- Review U.S. naturalization requirements on the USCIS website.
- Follow any required procedures to retain your original citizenship, such as re-registration or formal notification.
- Keep documentation such as birth certificates, citizenship certificates, and written confirmations from your embassy.
Conclusion
Dual citizenship can offer significant advantages, such as freedom to travel, access to services, and connection to your cultural roots, but it also comes with important responsibilities. U.S. law supports your right to hold more than one nationality, but the final decision rests with your country of origin. That’s why it’s essential to verify the rules, follow any required procedures, and stay informed about your legal obligations in both countries.
