How to Get U.S. Dual Citizenship Complete Guide

Having a thorough understanding of the laws dictating dual citizenship application in the United States is a great advantage for anyone filing for dual nationality at the office of the United States Citizenship and Immigration Services (or USCIS).

U.S. dual citizenship could be obtained either by birthright or by naturalization. Each of these two sources of dual nationality is achieved by following thorough procedures as required by United States immigration laws.

While the process may appear easy on paper, it can sometimes be complicated for an applicant who doesn’t have the prerequisite experience about the application process, cost, and scenarios by which the application process could be delayed or denied.

What Is U.S. Dual Citizenship?

Dual citizenship or dual nationality simply means being a citizen of two different countries at the same time. Immigration laws of most countries allow an individual to have dual nationality if they have met all the requirements of the laws of the two countries. In the United States, there are two ways through which you can obtain dual citizenship.

Learn about the difference between citizenship and nationality.

The first one is by birthright and parentage. It means a child born on United States soil to parents of another country is given automatic citizenship at birth. By being born in the country, the person can lay claim to citizenship of both the U.S. and his parents’ country of citizenship. The only exception to this is the children of diplomats born in the United States, who do not receive citizenship by being born in the U.S.

The second way that United States dual nationality could be obtained is by naturalization, either by getting married to a U.S. citizen or having stayed as a permanent resident in the country for a particular period of time. This country’s immigration laws allow a foreigner that is married to an American citizen to obtain citizenship and simultaneously maintain the citizenship of his or her country of origin. Also, a foreigner who may not be married to a U.S. citizen may be given United States citizenship while still keeping his or her citizenship of his country of origin. In the same way, a U.S. citizen can naturalize to another country and still maintain U.S. citizenship. Either way, you can obtain U.S. citizenship either as your country of birth or as your naturalized country.

Dual Citizenship Requirements in the U.S.

Whether you have received your U.S. citizenship by birth or naturalization, the dual citizenship requirements vary from country to country. This means that even if you have obtained U.S. citizenship, it might be the other country’s requirements that would not allow you to gain dual citizenship.

For example, you might have been born in India, but then your parents immigrated to the U.S., and you subsequently received U.S. citizenship. In that case, you would have gained American citizenship through naturalization. For one reason or another, you would probably want to inquire whether you could also gain Indian citizenship through your birthright citizenship. However, India, in particular, does not allow citizens to hold any other citizenship than Indian. For this reason, they automatically cancel your Indian citizenship as soon as the government is aware that you obtained citizenship in another country.

It is crucial to research which countries allow you to hold two citizenships so that you would be able to begin the process as soon as possible. Below you will find the list of countries that allow their citizens to hold citizenship in other countries.

How to Get Dual Citizenship in the U.S.

Just as it is in every sovereign nation, filling for U.S. dual citizenship has application process steps that must be followed diligently. To naturalize as a U.S. citizen, the first step is to get an immigrant visa (green card) to confirm that you have met all the requirements to live and work permanently in the U.S. The processes of getting U.S. dual citizenship according to the USCIS are as follows:

  • You must be at least 18 years old at the time of applying
  • Provide evidence of being legally admitted as a lawful permanent resident
  • Prove that you have continuously had a physical presence in the country for up to 5 years (or up to 3 years if you are applying as a spouse to a citizen of the United States)
  • You must have a record of good moral character
  • You have so far been compliant to the ideals and principles of the country’s constitution
  • You can read, write, and speak the English language at least at the basic level
  • You can prove that you have a basic knowledge of the country’s history and civic values

The success of these processes will lead to taking an oath of allegiance to the United States. Having successfully completed the process, you would get the certificate of naturalization which officially confirms your citizenship in the United States. This legally gives you the privilege to own and carry a U.S. passport wherever you go in the world. You will also have the right to vote during elections and enjoy all other rights accorded as a bona fide U.S. citizen.

How Much Does Dual Citizenship Cost?

To apply for U.S. citizenship, you have to get an N-400 form to process your application, and there are also biometric services to be conducted to run a background check on you. You will need to pay a total of $725 for these two services – $640 for the N-400 form and $85 for the biometric services fee. The whole payment can be made at once through different means, which include money order, cashier’s check, or personal check. 

USCIS has different fee schedules for dual citizenship fees depending on your background. Take a look at the table below to familiarize yourself with the costs.

What If My Dual Citizenship Is Denied?

One of the most frequently asked questions about U.S. dual citizenship is if an application could be denied and what to do if that happens. The N-400 form is divided into 18 parts and each section of the form requires that an applicant understands and fills it appropriately. Any error either by commission or omission in filling the form could result in an application denial. Also, the interview and payment procedures must be followed. It is within the USCIS prerogative to grant or deny your application based on the reasons including but not limited to the following:

  • Failure to sign the N-400
  • Failure to pay the filing fee and biometric services fee along with your form
  • Failure to give all information required in the N-400 or not supplying the required evidence

However, if your application gets rejected for any of the above reasons, USCIS will return the application to you including any fees paid, and explain to you why your application is deemed deficient. The good news, however, is that you may be given the opportunity of correcting the errors and resubmit the N-400.

In some cases, USCIS may consider it necessary to ask you for more information or evidence to back up some claims in your application. You may also be invited for an interview during which you may need to provide a fingerprint, photograph, or any other security-related information required to verify your identity. All these are done to verify your eligibility, which will lead to the USCIS decision as to whether you will be granted or denied citizenship.

Why You Should Get Dual Citizenship

Now that you know how to get dual citizenship, it’s time to learn why you should strongly consider doing so. There are probably endless benefits to being a citizen of more than one country. Below you will discover various advantages of being a dual citizen of the U.S. and another country.

Traveling – depending on your country of origin, having two passports, of which one is from the U.S., can open a lot more travel options. The U.S. passport is regarded as one of the best in the world for travel as it allows visa-free entry to numerous countries.

Guaranteed residence – as a holder of citizenship in any country in the world, you get absolute rights to have citizenship in that country. When you have more than one citizenship, this means that you can essentially pursue your life goals, career, and begin your family in either of the countries.

Social benefits – many countries worldwide allow their residents access to various social benefits and social security payments based on citizenship and/or residency requirements. Being a dual citizen will give you wider access to social benefits in more than one country. However, make sure to research the qualification criteria because some countries require you to at least partially live in the country.

Taxes – being a U.S. citizen allow you to benefit from lower tax rates in some states. Although the U.S. is not known to be the lowest-taxed country, it still offers much lower rates than many European and other western countries. This applies to personal and corporate taxes, which means it could be beneficial to start your business in the U.S.
