How to Obtain Dual Citizenship

Five Methods:Obtaining Dual Citizenship Through BirthplaceObtaining Dual Citizenship Through ParentageAcquiring Dual Citizenship by InvestmentAcquiring Dual Citizenship by MarriageAcquiring Dual Citizenship by Other MeansCommunity Q&A

With the exception of ‘stateless persons’ (those individuals without citizenship ties to any state), every person is a citizen of at least one state.[1] You may have become a citizen at birth if your state grants citizenship to people born within its territory. You might also be a citizen if your country grants its citizens’ children citizenship at birth regardless of where the children were born. You can also become a citizen through naturalization, which involves an application process and other criteria, such as a certain number of years of residence, marriage to a citizen, or financial investment. If you are interested in gaining dual citizenship, then there are several options you can look into.

Obtaining Dual Citizenship Through Birthplace

  1. 1
    Consider whether your country of birth grants you a second citizenship. Were you born in a state whose right to citizenship you have never exercised? If so, then you might be eligible for citizenship through an unrestricted right of soil, also known as unconditional jus soli. This means that you have an automatic birthright to be a citizen of that country because you were born there. For example, if you are currently a British citizen who was born in the United States, you are entitled to American citizenship through unrestricted jus soli.[2]
    • Research the immigration laws of your country of birth. Most countries do not grant citizenship through right of soil, so it is important to research the laws of the country in which you were born.[3]
    • 30 of the world’s 194 countries practice unconditional jus soli.[4] Of these 30 countries, Canada and the United States (as of 2010) are the only countries among the world’s advanced economies that practice unconditional jus soli and grant citizenship to most children born on its soil, including children born to persons present in the state illegally.[5]
    • However, children born in the United States to foreign diplomats and foreign heads of state do not acquire citizenship through right of soil.
  2. 2
    Find out how to exercise citizenship through unrestricted right of soil. You may find that your country of birth, which is not the country whose citizenship rights you exercise, grants you a right to its citizenship through a right of soil. If so, discover how you can exercise that right.
    • One way to exercise a right to citizenship is to apply for a passport. You can apply for a passport through the state’s embassy or consulate in your current country of citizenship and/or residence. You may be asked to present an original or certified copy of your birth certificate to the consulate or embassy as evidence.
    • For example, if you apply for a Canadian passport, then you can present a birth certificate issued by the Canadian province or territory in which you were born. This serves as evidence of your Canadian citizenship because Canada practices unrestricted jus soli.[6]
  3. 3
    Research the laws of both states regarding dual citizenship. Find out the laws regarding dual citizenship of both the state of your current citizenship and of the state whose second citizenship you are trying to obtain. Consider whether enforcing your right of soil citizenship may require renouncing your current citizenship. This is important because not all states that practice unconditional jus soli permit their citizens to hold dual citizenship.
    • For example, Pakistan practices unconditional jus soli (with a few minor exceptions) but only permits dual citizenship with a select number of states.[7][8]
    • Examples of countries that both practice unconditional jus soli and permit dual citizenship are the United States and Canada.[9][10]

Obtaining Dual Citizenship Through Parentage

  1. 1
    Consider your parents’ citizenship. Most countries in the world grant citizenship on the basis of right of blood or jus sanguinis. Under the jus sanguinis principle, you acquire one or both of your parents’ citizenship upon birth.[11] This means that the child acquires the parents’ citizenship regardless of where she is born, and her only citizenship is the one acquired through right of blood if she is born in a country that does not practice jus soli.
    • For example, if you were born in the United States, but your parents are both British citizens, then you are also a British citizen.
  2. 2
    Research the laws regarding dual citizenship of both countries. Find out if obtaining a second citizenship through the jus sanguinis principle of a state would require you to renounce your prior citizenship. If that is the case, you cannot become a dual citizen.
    • Both the United States and the United Kingdom permit dual citizenship. However, there are other countries that grant citizenship on the jus sanguinis principle and do not permit dual citizenship.[12][13]
    • Singapore, for example, practices jus sanguinis but does not allow dual citizenship.[14][15]
  3. 3
    Find out how to exercise your citizenship through right of blood. The process that you will need to follow to gain citizenship through parentage will vary by country. Check with the country’s consulate to determine what you will need to do.
    • For example, if you are currently an American citizen who was born to British parents, and you are under the age of 18, it is your parents who must apply on your behalf to register you as a British citizen. The application form and guidance on how to register as a British citizen in this scenario are available here.

Acquiring Dual Citizenship by Investment

  1. 1
    Consider acquiring a second citizenship by investment. Many countries issue resident visas or permits to individuals who are willing to invest in the country’s economy, and those resident visas can make you eligible for citizenship after a few years. This can be an expensive route as the minimum investment amounts range from several hundred thousand dollars to several million dollars.[16]
    • For example, the United States requires an investment of $1 million (or $500,000 if you are investing in a high unemployment or rural area), and in return you receive a conditional permanent resident permit.[17]
  2. 2
    Find out how long it will take to become a citizen by investment. This path to citizenship can take a long time, so research the amount of time that it will take you to become a citizen before you decide to invest.
    • For example, the United States and Belgium grant citizenship after five years of holding a resident permit of this type. However, Malta (whose minimum investment requirement is EUR 1 million) grants citizenship after only 1 year.
  3. 3
    Check to see if there is a residency requirement. Some states that grant investor visas also require that you remain a resident in that state before you can become a citizen. However, not all countries have residency requirements.
    • For example, Cyprus does not have a residency requirement but the United States does.[18]
  4. 4
    Check the citizenship laws of the country in which you are investing. Not all countries permit dual citizenship. You may be required to renounce your prior citizenship in order to acquire citizenship by investment. If that is the case, you cannot become a dual citizen in this way.

Acquiring Dual Citizenship by Marriage

  1. 1
    Consider your spouse's citizenship. If you are married to someone who holds a citizenship that you do not, then you might consider whether your spouse’s country of citizenship grants you citizenship by marriage. This process involves applying for a resident permit that you would qualify for based on your marriage. You would also need to meet any residency requirements.
    • If you believe that you can acquire a second citizenship through marriage, research the laws of your spouse’s country of citizenship regarding citizenship by this route. The laws about the application process and amount of time involved to obtain citizenship will vary by country.
    • For example, if you are married to a British citizen, you must meet certain requirements before you can apply to become a British citizen by marriage. You must be 18 years of age or older, of sound mind, of good character (e.g. you don’t have a serious criminal record), you must meet English language requirements and show knowledge of life in the UK, you must have been granted indefinite permission to stay in the UK, and you must meet a residency requirement.[19]
  2. 2
    Beware of the consequences of sham marriages. Note that entering into a sham or fake marriage for the sole purpose of acquiring residency and (subsequent citizenship) of your spouse’s country is considered fraud and is a serious criminal offense in most countries. Do not attempt to enter into a sham marriage for the purpose of becoming a dual citizen, as the legal consequences of this can be severe.[20]
  3. 3
    Confirm the laws regarding dual citizenship of both countries. Not all countries permit dual citizenship, and your spouse’s country of citizenship may be one that requires you to renounce your previous citizenship. If that is the case, then you cannot become a dual citizen through marriage.

Acquiring Dual Citizenship by Other Means

  1. 1
    Apply for an employment visa. You may also gain citizenship by applying for a job in another country. Some countries allow individuals who have legally entered the country on a work visa to convert their visa status to permanent residency and then to citizenship.
    • For example, in Australia you can apply for a number of categories of employment visas that have their own requirements. One type is called a Skilled-Independent Visa and it allows you to enter Australia with the intention of working in Australia as long as you meet the criteria. If you spend four consecutive years in Australia under the visa, then you become eligible for Australian citizenship.[21]
  2. 2
    Apply for residency through special immigration programs. In many countries, the first step to becoming a citizen is to apply for residency. Once you become a resident, you may then apply for citizenship through naturalization. Eligibility requirements vary from country to country.
    • For example, in the United States you can qualify for permanent residency through the Diversity Immigrant Visa Program. This program randomly draws from a pool of individuals who are from countries with low rates of immigration to the United States.[22]
    • Check to see if the country in which you are interested in acquiring a second citizenship has a similar route to acquiring residency.
    • Once you acquire residency and meet any other criteria, then you can apply for citizenship.
  3. 3
    Confirm the laws regarding dual citizenship of both the countries. Keep in mind that not all countries permit dual citizenship. If you acquire citizenship of a state through a work visa, visa lottery, or other program, then you may be required to renounce your prior citizenship. If that is the case, you cannot become a dual citizen by following this route.

  • If my grandparents were Irish immigrants, am I eligible for dual citizenship?
    wikiHow Contributor
    Ireland has a citizenship-through-ancesory program, but you'd need to contact a service that specializes in citizenship acquisition or the local Irish consulate to inquire about the requirements for it. As far as programs go, it is more simple than most, but there are no guarantees when dealing with bureaucracy. You will have to research the requirements, and determine if you meet them and qualify. If that is the case, a passport may be had for a few processing fees.
  • I was born and resided in Canada for 40 years, became a US citizen in 2010, do I still have dual citizenship?

  • I am an American looking for dual citizenship in any EU country. Can you tell me which EU country has the least stringent citizenship requirements and what the requirements might be?
    wikiHow Contributor
    This depends on how much money you have available. Malta for instance, requires an investment of about 1 million Euros, but the timeline is only one year. Belgium on the other hand, may grant you a residency permit for starting a qualifying business (with about 60-70 thousand Euro of capital), and if you reside there for 5 years, you may apply to be naturalized. Others, like Ireland and Bulgaria, have a similar program for residency. Swiss citizenship is probably the longest timeline to citizenship (at 12 years of residency), and in some like Germany and the Netherlands, dual citizenship is restricted to specific cases. You can do an online search for the additional requirements for each program.
  • I am an American citizen through naturalization. How do I go about getting a second (dual) citizenship from Canada and what are the requirements?

    You would also have to move there and naturalize, then apply and take the test. You can fast track with service in the Canadian military. You must have been physically present in Canada as a permanent resident for at least 1,460 days during the six years immediately before the date of your application. You must also be physically present for at least 183 days during each of four calendar years that are fully or partially within the six years immediately before the date of application.

  • How can I get citizenship in another country?
    wikiHow Contributor
    Through ancestry, if the country offers it, and you can prove you meet the requirements, investment, or naturalization. Typically, the quickest and most expensive route open to everyone is through investment, though not all countries offer such a program. Naturalization is slower, but can be had for much less money. Being a skilled worker helps, as you will first have to obtain residency, then wait out the required duration for citizenship. You can do an online search for details about a particular countries offers: Don't be afraid to shop around!

    • For each method of acquiring citizenship, you will need to fill out a set of forms relevant to the type of citizenship or residency that you seek. These forms and processes will vary by country. Guidance and other information on what forms to fill out and what processes to follow are available at the official consular websites of the state in question.
    • Remember that your country of citizenship may allow dual citizenship but not encourage it as a matter of policy. The United States allows dual citizenship as a matter of law but discourages it as a matter of policy because of the problems it may cause. These problems include difficulty in providing consular protection in those instances in which U.S. law conflicts with the law of the other state whose citizenship you hold.[23] The country where you are located will generally have a greater claim to your allegiance, and this may cause problems if that country does not have a stable political relationship with the United States.
    • Remember that dual nationals are required to follow the laws of both states of which they are a citizen. Either country will have a right to enforce its laws upon you, in particular if you travel to that country.[24]
