The USA allows its citizens to hold dual citizenship, which means you don’t have to give up your American passport if you choose to obtain a second one.
Essentially, US law does not force citizens to select only one nationality at birth or upon naturalization. While this flexible policy offers greater freedom, it also brings extra responsibilities regarding taxes, legal matters, and passport management.
In this blog post, we explore key aspects of US dual citizenship, highlight popular countries that allow second passports, review various paths to acquiring additional nationalities, and offer strategies for managing more than one passport.
62 countries in the world allow dual citizenship with the US. But keep in mind that while the United States permits dual nationality, the exact rules and conditions vary by country.
Dual citizenship means you legally hold the nationality of two countries at the same time. Each country gives you rights, such as the ability to live, work, and vote (where applicable), and also requires you to follow its laws.
Some people are dual nationals from birth. For example, a child born in the United States to foreign parents might gain US citizenship through birthright and also inherit the parents’ nationality.
Others apply for citizenship in a second country later in life, perhaps through investment, marriage, or ancestry-based routes.
There are many countries around the world that allow US citizens to hold dual citizenship. Each destination comes with its own set of rules and conditions, making it essential to understand the specifics before proceeding.
Let’s explore some of the most popular options, especially those offering direct citizenship by investment programs, from various parts of the globe.
Malta offers an official citizenship program that generally involves making a qualifying contribution, maintaining property (rental or purchase), and meeting a residency requirement.
Dual citizenship is recognized, and successful applicants gain EU mobility privileges. Applicants should pass thorough background checks and uphold any ongoing obligations.
Portugal has attracted American passport holders interested in eventual European citizenship. A common route is via a “Golden Visa” program involving real estate or a different financial contribution.

Spain offers pathways based on long-term residency, marriage, or ancestry for those with Spanish parents or grandparents. The standard naturalization route requires around 10 years of continuous residence, though it can be shorter for certain categories.
Spain’s approach to multiple citizenship is more complex than Portugal’s, but in practical terms, many Americans retain their US passport once they become Spanish nationals.
It is crucial to double-check if any formal renunciation is demanded during the application. Official government sites or well-regarded news outlets typically clarify the details.
Italy’s jure sanguinis route grants citizenship to people with Italian ancestry through paternal or maternal lines, provided the lineage was never broken by an ancestor renouncing Italian citizenship before the birth of the next generation.
Non-ancestry naturalization usually involves several years of residency, plus proficiency in the Italian language.
Italy recognizes dual nationality with the United States, making it popular among Americans who have deep Italian roots.
The St. Kitts & Nevis program has a well-established legal framework for citizenship through investment. Applicants can contribute to the Sustainable Growth Fund or invest in select real estate.
According to official government announcements and data from recognized media, this route helps St. Kitts & Nevis fund national projects.
Grenada’s citizenship by investment option similarly involves a financial contribution or property purchase.
The local law does not require applicants to renounce previous nationalities, so multiple citizenship in the USA is feasible for American passport holders.
Antigua & Barbuda’s regulations enable individuals to apply through several investment channels, such as contributions to the National Development Fund or real estate investments.
The country has recognized dual nationality for years, making it a straightforward choice for those seeking a Caribbean second passport for Americans.
Dominica’s official program includes donation or real estate options, known for relatively accessible financial thresholds compared to some other locales.
The government allows multiple citizenship, which helps maintain American passport.
Saint Lucia has become a favoured spot for some Americans aiming to add a second passport. Government rules let foreign nationals gain citizenship through different investment routes.
Local regulations do not force an applicant to give up their original nationality.
Turkey’s citizenship by investment plan includes real estate purchases above a certain threshold or making fixed capital contributions. Authorities check applicants’ backgrounds to ensure good conduct.
Turkey recognizes multiple passports, letting American passport holders keep their US status.
Vanuatu’s government program is known for a relatively quick timeline. By contributing to a designated development fund, foreigners can become citizens without long residency.
Although Vanuatu is more distant geographically, it allows dual nationality with the United States.
Nauru is a tiny island nation in the Pacific, but with a great citizenship program. Officially, it accepts dual citizenship if you meet the criteria.
People often go through specialized channels, and the rules or fees can change, so it is wise to consult official data.
If your plans to move and relocate relate to legal concerns in the US, note that some of the countries we mentioned are considered non-extradition jurisdictions. For more information, read here.
Rules around holding two passports can seem confusing, yet US law in this area is more flexible than many realize. There is no explicit requirement in the Immigration and Nationality Act to drop other citizenships if you become an American, and likewise, you do not automatically lose US nationality by taking on a foreign one.
The US Supreme Court and official policy from agencies like USCIS have clarified that dual nationality is permitted, as long as certain conditions are met.
Here are a few specific laws and guidelines that shape how dual nationality with the United States works:
1. Immigration and Nationality Act (INA): This act outlines how someone can acquire or lose US citizenship. It does not forbid holding multiple nationalities, although certain sections cover acts that might indicate an intention to relinquish US citizenship.
2. Department of State Policies: Official State Department resources confirm that an American does not automatically renounce US citizenship by obtaining another passport. Intent matters. If you clearly intend to keep your US status, you usually do.
3. Oath of Allegiance: Naturalizing in another country often involves an oath or pledge. If it explicitly states renunciation of all other allegiances, the US might interpret it as a sign of giving up US nationality. However, this depends on each situation, and many modern oaths do not require a complete forsaking of previous citizenships.
Yes. An American may hold several passports if these countries allow it. The principle is that the United States does not demand renunciation of your US passport when you obtain foreign nationality.
At the same time, not all nations share this openness. Some countries automatically revoke local citizenship if you become a citizen elsewhere.
The best approach is to consult reputable government websites or recognized news outlets in the relevant country to confirm it accepts multiple nationalities.
Many American passport holders pursue a second passport to extend their travel, residence, or business capabilities. Here are common advantages:
Although multiple citizenship USA appeals to many, it carries some drawbacks as well, that is better to know before going further:
Some people qualify for an additional passport without special effort, for instance, if it was granted at birth. Others must follow a formal legal process.
Here are the main paths to dual nationality with the United States:
Citizenship by investment in the USA is not offered by the United States, but many other nations have official frameworks allowing foreigners to become citizens after making certain contributions or investments. The Caribbean region is known for such routes, as are some European countries.
Often, an investment in real estate or a government development fund is required, along with administrative fees. Processing can be relatively fast, ranging from a few months (like in Saint Lucia) to over a year (like in Malta).
Key Features:
When done lawfully and in compliance with each country’s criteria, this can be a direct, though sometimes expensive, method to secure a second passport for Americans.
A significant number of Americans have roots in Europe, Latin America, or other parts of the world. Countries like Italy, Ireland, and Poland offer routes to nationality if you can prove lineage.
This method is often more affordable than investment-based paths but can be time-consuming. Gathering birth certificates, marriage records, and other documents spanning generations can be intricate.
For example, Italy provides jure sanguinis (right of blood). If an individual can show uninterrupted Italian ancestry through a direct line, citizenship may be granted. Similar policies exist in other places, though rules vary widely.
Americans residing abroad often qualify for a second passport via naturalization after meeting certain criteria:
These steps may take 3-10 years, depending on the country. Portugal and Spain have specific waiting periods for foreign residents. Italy has standard naturalization for those who have lived there long enough.
When you marry a citizen of the target country, you can often benefit from an expedited naturalization process. Requirements typically include providing a legally valid marriage certificate and additional documentation to prove the genuineness of the relationship.
Many countries require that the couple remain married for a certain period before citizenship is granted. Processing times for marriage-based citizenship can vary but generally range from 2 to 5 years, depending on local regulations and the efficiency of the application process.
1. US Passport Usage: You must typically enter and leave the United States on your valid American passport, even if you have another nationality.
2. Local Law Variations: Some countries do not officially forbid multiple citizenship but may place conditions on how it is recognized. Confirm specifics with that nation’s official legal sources.
3. Tax Filing Duties: US citizens must report worldwide income, and the second country might have its own tax system. Double-check local tax treaties or consult professional guidance.
4. Children’s Citizenship: Children born in the US are usually American by birth. They may also inherit the second country’s nationality if one parent is from there, subject to that nation’s rules.
5. Potential Military Service: A few nations still require citizens to register for or complete military obligations. If you are a dual citizen, you could be subject to those regulations.
6. Diplomatic Protection: When you are in the US, you are primarily considered American. When you are in your other country, you are regarded as a local citizen. That can limit US consular protection.
Obtaining a second citizenship is only the first step; after, there are obligations and privileges linked to each nationality that must be followed to maintain dual citizenship.
A dual national must comply with laws in both countries. When in the United States, local statutes apply fully. When in the other country, you are subject to its legislation, including possible requirements for registration, local taxes, or other formalities.
Always keep valid passports and identity documents for both nationalities. Some countries require you to register life events (marriage, birth, or name changes) with their authorities.
The US Internal Revenue Service (IRS) taxes American citizens on worldwide income. This does not necessarily mean double payments, as the United States has treaties with many countries and offers the Foreign Earned Income Exclusion and foreign tax credits.
Still, an American passport holder with foreign income must file an annual US tax return. The second country may also impose its own taxes. Timely consultation with reliable resources, such as the IRS official website, can keep you on the right side of the law.
You must show a US passport when entering or exiting the United States. Airlines commonly ask for passport details, and border authorities can fine or delay travellers who fail to produce the correct documents.
If travelling to your second country, it could be advantageous to also carry that nation’s passport for visa-free entry. However, do not attempt to use your foreign passport to enter the US, as that can create confusion about your American status.
Some countries place restrictions on dual nationals in specific government positions or require official notification of the second citizenship. Check whether you need to inform the second nation’s immigration office or local authorities about your US citizenship.
People with multiple citizenship enjoy easier mobility. For instance, an American with a European passport can travel within the Schengen Area with minimal bureaucracy.
A Caribbean passport might grant simpler access to certain nations in that region. Having more than one passport can also provide peace of mind if travel restrictions affect one nationality but not the other.
Before diving into any application, weigh the financial, legal, and personal implications:
Dual citizenship applications can be lengthy. But the process can be streamlined, if you implement the right approaches:
Children can automatically inherit citizenship depending on the laws of the second country. For example, a child born in the US to a Maltese parent may be eligible for Maltese nationality.
Meanwhile, if you become a Grenadian citizen through investment, your minor children might be included in your application, granting them dual nationality with the United States as well.
Staying informed about registration timelines is essential. Some countries require immediate notification of a child’s birth or an application for a citizenship certificate within a limited period. Missing these deadlines can complicate your child’s future eligibility.
A small minority decide to let go of their American dual passport. This step is usually taken for personal or tax reasons.
Official renunciation of US citizenship is done in person at a US embassy or consulate. The process can involve:
1. Formal Oath: You must appear before a consular officer, sign documents, and verbally confirm your decision.
2. Irreversible Consequences: Giving up US citizenship is serious. You lose the right to live or work in the US as a citizen, vote in American elections, or claim certain protections.
3. Tax Requirements: The IRS may request an exit tax or final filings, depending on your assets and timeline.
The vast majority of people who pursue multiple citizenship USA do so intending to keep their American status. Renunciation is rare but remains an option for those with specific motivations.
Having a second passport can enhance day-to-day possibilities:
1. “You Automatically Lose Your US Citizenship if You Obtain Another.”: In general, this is not true. The United States does not require forced renunciation unless you clearly intend to relinquish your American status.
2. “Dual Citizens Do Not Pay US Taxes.”: US citizens, including dual nationals, must report worldwide income to the IRS. Some avoid double taxation through credits or exclusions, but a filing obligation typically remains.
3. “There Are No Restrictions.”: While the US permits multiple nationalities, certain high-level US government jobs might require holding only American nationality for security reasons. Also, the second country might enforce its own limitations.
4. “Dual Citizenship Is Illegal Everywhere.”: Global approaches vary. A handful of countries do not tolerate any additional passport. Others permit multiple citizenship for citizens, but with strings attached.
5. “Using a Foreign Passport to Enter the US Is Fine.”: By law, a US citizen must generally use a valid American passport to enter or exit the United States, even if holding another nationality.
Dual citizenship with the United States can greatly expand your global horizons. It can simplify travel, provide an alternate residence, and reinforce ties to heritage or family.
Yet it also carries responsibilities: more than one passport means more legal obligations. For many Americans, the benefits outweigh the drawbacks, especially if they plan carefully and stay informed about the rules in each country involved.
A solid approach involves confirming that your intended second country unambiguously accepts dual nationality with the US.
Reach out to field professionals, like Savory and Partners, for a smooth and strategic approach to second citizenship planning.
In most cases, no. US law does not automatically strip citizenship when a person acquires another nationality. However, an individual’s actions might be interpreted as intending to relinquish US status—such as explicitly renouncing it at a foreign embassy. Consult official US Department of State resources for further details.
American citizens are required to use a valid US passport whenever entering or leaving the country. While you may hold another passport, the US government expects you to present your American passport at US ports of entry.
The United States taxes citizens on worldwide income, regardless of other nationalities. Some treaties and exclusions (such as the Foreign Earned Income Exclusion) can help minimize double taxation. Still, you must generally file a US tax return each year, plus meet any filing obligations imposed by your second country.
No specific notification is required unless you intend to renounce your American citizenship. The US primarily cares that you maintain a valid US passport for travel in and out of the country. The second country, however, might ask you to declare or register your US citizenship, so stay updated on local rules.
Some nations automatically revoke local nationality if you gain a new passport, and others require you to formally renounce your original citizenship. If the second country disallows dual status, you may be forced to choose between your US and foreign citizenship. Confirm how local laws approach additional nationalities before applying.
Certain countries may enforce compulsory military duties for all citizens. Although these policies are less common now, a dual national may still be subject to local conscription if the law applies. Research the regulations in your second country to avoid unexpected obligations.
