What is a second passport calculator?
A second passport calculator is a tool that shows what a second citizenship would add to the passport you already have.
It counts the extra countries you could visit without arranging a visa first, and the places the second passport would let you live and work.
Why get a second passport?
People get a second passport for different reasons:
- More countries without a visa, if yours needs one for much of the world
- The right to live and work somewhere new, or in 31 European countries at once with an EU passport
- A plan B if things change at home
- A citizenship to pass on to their children
For most people, one of the first 2 decides which passport is worth the effort.
What a second passport adds
Here's the biggest add for 9 passports on September 26, 2026, and the best from the EU and EEA:
| Your passport | Countries now | Biggest add | Best EU or EEA add |
|---|---|---|---|
 United States | 148 | UAE +25 | Czechia or Croatia +8 |
 United Kingdom | 151 | UAE +23 | Czechia, Ireland, Luxembourg or Malta +5 |
 Canada | 150 | UAE +23 | Czechia, Ireland or Malta +6 |
 Brazil | 142 | UAE +28 | Czechia +15 |
 Mexico | 130 | UAE +39 | Ireland +26 |
 China | 83 | UAE +85 | Ireland +79 |
 Philippines | 58 | UAE +113 | Ireland +100 |
 India | 52 | UAE +117 | Germany, France, Ireland and 6 more +104 |
 Nigeria | 41 | UAE +131 | France, Germany or Italy +126 |
"Countries now" counts the countries your passport enters without a visa arranged first. An add counts the countries the second passport opens where yours needs a visa, its own country included.
The biggest add isn't always the best pick
The UAE passport tops every list above. But the UAE's usual rule asks for 30 years of residence before citizenship, and it allows dual citizenship only in some cases. Singapore, Japan and Malaysia, near the top for most passports, don't allow dual citizenship at all.
That's why the calculator has 3 filters:
| Filter | Shows |
|---|---|
| EU and EEA | The 31 passports of the EU, the EEA and Switzerland, each with the right to live and work across all of them |
| Citizenship in 5 years or less | Countries whose usual residence rule is 5 years or less |
| Allows dual citizenship | Countries that let you keep your first citizenship |
A US passport plus an EU one
For an American, an EU or EEA passport adds 4 to 8 countries without a visa in advance, most of them 6 or 7. Ireland adds 7: Belarus, Brazil, Burkina Faso, China, Iraq, Uganda and Venezuela.
The bigger gain is where you can live. An Irish passport adds the right to live and work in 32 countries: Ireland itself, the other 26 EU countries, Iceland, Liechtenstein, Norway, Switzerland and the UK.
A second passport doesn't change your US taxes, though. The US taxes its citizens wherever they live, whatever other passports they hold.
Ways to get a second passport
| Route | How it works |
|---|---|
| Descent | Many countries pass citizenship to the children, and sometimes grandchildren, of citizens born abroad. Ireland, for one, accepts a grandparent born on the island of Ireland. |
| Residence | Live in the country for a set number of years, then apply to naturalize. |
| Marriage | Many countries shorten the wait for the spouses of citizens. |
| Investment | A few countries grant citizenship for an approved investment, mostly small island states. The EU's Court of Justice ruled Malta's program against EU law in April 2025. |
How long residence takes
Wikipedia's naturalization table, read on September 27, 2026, gives each country's usual residence rule:
| Country | Years of residence | Dual citizenship |
|---|---|---|
 Argentina | 2 | Yes |
| Canada | 3 | Yes |
 Australia | 4 | Yes |
| Brazil | 4 | Yes |
 Germany | 5 | Yes |
 Ireland | 5 | Yes |
| United States | 5 | Yes |
| Mexico | 5 | In some cases |
 Panama | 5 | No |
 Italy | 10 | Yes |
 Spain | 10 | In some cases |
 Japan | 10 | No |
Many countries have shorter routes. Spain asks 2 years of natural-born citizens of Ibero-American countries, and Brazil one year of people with a Brazilian spouse or child. Most also ask for a language test, a clean record and time spent in the country.
Your own country's rules come first
A second passport only helps if you can keep the first. India, for one, doesn't allow dual citizenship: Indians who take another citizenship lose their Indian one, though they can apply for Overseas Citizenship of India.
The calculator warns you when your own country doesn't allow dual citizenship, and when it taxes citizens who live abroad.
Before you apply
- Check that your own country lets you keep its citizenship
- Check whether the new country taxes citizens who live abroad
- Check what the route asks of you each year, like days spent in the country
- Get advice from a lawyer licensed in that country before you pay anyone
Residence routes count your days, so keep a record with the 183-day rule calculator. The calculator shows what a passport opens, not whether you qualify for it. That part is always the country's own rules.
How to use the second passport calculator

Where the data comes from
The visa rules come from Wikipedia's "Visa requirements for … citizens" articles, one per passport, read every week. Dual citizenship and years to citizenship come from Wikipedia's naturalization table, and tax on citizens abroad from its international taxation table.
Where a passport lets you live and work comes from the agreements themselves: free movement in the EU, the EEA and Switzerland, the Common Travel Area, the Trans-Tasman Travel Arrangement, the Gulf Cooperation Council, the Eurasian Economic Union, the Mercosur Residence Agreement, the treaty between India and Nepal, and the Compacts of Free Association with the US.
The dates under the tool show when each source was last read. Rules change, so check the country's official page before you act on anything here. It's information, not legal or tax advice.
Who is the second passport calculator for?
It's for anyone thinking about a second citizenship, by descent, residence, marriage or investment, and each of them has a next step:
- Compare passports – people with a claim by descent, to see what it's worth before the paperwork
- 183-day rule calculator – digital nomads and founders on a residence route, counting their days
- Passport index – parents weighing the citizenships they can pass on
- What is a global citizen? – my own story, from Stockholm to a home base in Panama

Second Passport Calculator FAQs
Questions about getting a second passport? Here's what to know.
A second passport calculator shows what another citizenship would add to the passport you have.
It counts the new countries you could enter without a visa arranged first, and the new places you could live and work.
On travel alone, the UAE passport adds the most for an American: 25 countries without a visa in advance.
Among EU passports, Czechia and Croatia add 8, and Ireland adds 7, plus the right to live and work in 32 countries, the UK included.
You can hold 2 passports if both countries allow dual citizenship.
Of the 199 passports in the calculator, 101 come from countries that allow it, 45 from countries that allow it in some cases, and 49 from countries that don't.
Descent is often the fastest, if a parent or grandparent gives you a claim.
By residence, Wikipedia's naturalization table lists Argentina at 2 years and Canada at 3.
China, India, Japan, Malaysia, Saudi Arabia and Singapore are among the 49 countries whose rules don't allow dual citizenship, per Wikipedia's naturalization table.
The calculator warns you when yours is one of them.
Mostly not, since most countries tax by where you live, not by passport.
The US, Eritrea and a few others tax their citizens wherever they live, so check the new country's rule before you apply.
A second passport adds the countries it enters without a visa arranged first where yours needs one.
It can also add the right to live and work in new countries, like the 30 other European countries an EU passport opens.
The second passport calculator is free, with no sign-up.
The second passport calculator is for people weighing citizenship by descent, residence or investment, digital nomads and parents planning for their children.
