One of the most common questions when planning a life in another country is: how long until I can get the passport? The answer varies drastically by continent —in Argentina 2 years of legal residence suffice, while in San Marino, Liechtenstein or the United Arab Emirates we would be talking about 30—. This comparison uses the verified data from TransitNous’ 198 nationality files, cross-checked against public sources in 2026.
How long does naturalization take in each continent?
Median years of ordinary residence required to naturalize, by region:
| Region | Median | Fastest | Longest |
|---|---|---|---|
| South America | 2-5 years | Argentina, Peru (2) | Venezuela (10) |
| North America | 3-5 years | Canada (3 of the last 5) | United States (5) |
| Asia | 5 years | Singapore (2), Israel (3) | United Arab Emirates (30) |
| Europe | 7 years | Poland, Armenia, Serbia (3) | San Marino, Liechtenstein (30) |
| Central America and the Caribbean | 5-7 years | Nicaragua (4) | Saint Kitts and Nevis (14) |
| Oceania | 8 years | Australia (4) | Palau (15) |
| Africa | 7 years | Liberia (2), Ethiopia (4) | Chad, Nigeria, Seychelles (15) |
South America: the fastest continent
If speed is what drives you, South America is unbeatable: Argentina and Peru require only 2 years of continuous legal residence, and Ecuador matches them in practice. Paraguay requires 3, and Brazil —if you are married to a Brazilian or have a Brazilian child— 1 year. The trade-off is administrative time: processing often takes as long as the residence itself. One peculiarity: in Argentina the clock runs from legal residence and, since Decree 366/2025, the 2-year material threshold stands, although the effective-residence test became stricter.
North America: rules with a catch
- Canada: 3 of the last 5 years as a permanent resident (1,095 days), with language proof and a civics knowledge test.
- United States: 5 years as a permanent resident (3 if your spouse is a US citizen), with civics and English tests. The Green Card is not naturalization; it is the prerequisite.
- Mexico: 5 years of residence, reduced to 2 for those born in Ibero-America and 1 under Article 20 of the law.
Europe: the region of the 2024-2026 reforms
Europe is going through an intense period of legislative change:
- Germany cut the requirement from 8 to 5 years in June 2024 (3 in cases of exceptional integration, although the express route was abolished in the 2025 reform).
- Portugal tightened: Law 1/2026 raises the timeframe to 7 years for most and 10 years for non-CPLP citizens, moving away from the Iberian average.
- Sweden approved a tightening in June 2026: from 5 to 8 years (changes enter into force gradually).
- Netherlands, Belgium, France and Luxembourg remain around 5 years… with exceptions: Belgium applies 5 with labor-market integration, while France allows a reduction to 2 with French higher education. Sweden is already counted.
- Spain is the country with the greatest internal contrast in the world: 10 years as a general rule, but 2 years for Ibero-Americans, Andorrans, Filipinos, Equatorial Guineans, Portuguese and Sephardic Jews, and 1 year after marrying a Spaniard.
The European extremes remain San Marino, Andorra, Liechtenstein and Monaco (10 to 30 years), small countries where the status is deliberately restrictive.
Asia: from Singapore’s 2 to the UAE’s 30
Asia shows the widest internal dispersion:
- Singapore accepts applications from 2 years, although deciding whether to grant it can take 1-2 more.
- Israel (3), Japan (5, in practice “3 consecutive years” is assessed for many profiles), South Korea (5) and Taiwan (5) are the middle band.
- The Gulf is the opposite pole: Saudi Arabia (10, selectively), Kuwait and Oman (20), Bahrain and Qatar (25), United Arab Emirates (30)… and effective naturalization is even harder than the numbers suggest, with discretionary approvals and no right of appeal.
Oceania and Africa: the least known data
- Australia requires 4 years of residence (1 of them as a permanent resident) and New Zealand 5. In the smaller Pacific, times rise to 15 years in Palau or 10 in Vanuatu.
- In Africa the median is 7 years. The shortest are Liberia (2) and Botswana, which in practice allows naturalization in about 5. The longest, Chad, Nigeria and Seychelles (15). Several recent constitutions (Kenya 2010, Uganda 2019) have clarified the timeframes without shortening them.
The no-waiting route: citizenship by descent
If you have European parents or grandparents, you can skip the entire table: ius sanguinis requires no years of residence.
- Italy: the most famous route, although Law 74/2025 limited transmission to those with a father, mother or grandfather born in Italy (the unlimited chain is gone).
- Ireland: if a parent or grandparent was born on the island, you can register in the Foreign Births Register without ever having lived there.
- Poland, Hungary, Croatia and Lithuania: similar processes for descendants of the great 20th-century emigrant diasporas.
- Spain, grandchildren law: the provision of the Democratic Memory Law allowed descendants of exiles to apply for nationality; the extraordinary deadline ended in October 2025 and the last cases are currently being processed.
These processes do not require living in the country, but document management times (apostilles, translations, historical records) mean that in practice they take 1-3 years.
The citizenship-by-investment shortcut: the exception to the rule
This comparison is about naturalization by residence, but the route that breaks the table must be mentioned: citizenship by investment programs (CBI). Antigua and Barbuda (from USD 230,000), Grenada (USD 235,000), Dominica (USD 200,000), Saint Lucia and Saint Kitts and Nevis allow you to obtain a passport in 4-9 months with no prior residence, although they raised their amounts after the joint Caribbean memorandum of 2024 that set the floor at USD 200,000 effective from mid-2024. Vanuatu offers the fastest route (45-60 days for USD 130,000), but its passport no longer grants visa-free access to the Schengen area since 2022-2024. Outside the Caribbean, the Egyptian investment route is regulated by Law 190/2019.
Administrative times: the hidden half of the wait
The residence years are not the only time involved; administrative processing can add 1 to 3 more years in practice:
- Argentina: on top of the 2 years of residence there is the naturalization trial, which can last 18-36 months depending on the court.
- Canada: the application takes 10-14 months once the requirement is met.
- Spain: the national procedure is known for delays of 1.5-3 years from application to oath, although the digital reform promised to shorten it.
- Germany: between 6 months in agile states and 24+ months in large cities like Berlin.
- Switzerland: in addition to the 10 federal years, the cantonal and municipal process can add 1-2 more years.
That is why it is worth thinking in terms of “years until passport in hand”, not just the legal residence threshold.
Recent reforms that change the ranking
- Italy, Law 74/2025: generation limit for ius sanguinis, but it keeps the residence requirement at 10 years, with reductions (3 for exiles and those of Italian origin, 4 for EU citizens).
- Germany: 3-year express route abolished in 2025; already mentioned.
- Sweden 2026: from 5 to 8 years (2026 Citizenship Law).
- Portugal: new Law 1/2026 with 7 and 10 years depending on origin — see the updated file.
Another recurring source of delay is documentary requirements: apostilled birth certificates, criminal records from every country lived in over the last 5-10 years and sworn translations. Many files get “stuck” not because of the State, but because of an expired or poorly translated document; if your goal is certain, start collecting paperwork from the first year of residence.
To choose where to plant your flag
When comparing, remember that residence years are not the only relevant figure:
- Dual citizenship allowed (holding both changes the equation a lot: see our dual citizenship article).
- Language and integration requirements, usually the real barrier in Europe.
- Discretionary approval: in some countries the timeframe only entitles you to apply, with no guarantee of approval (Gulf, Switzerland, Austria).
- Administrative times: Peru 2 years plus 12-18 months of processing; Canada another 12-24 months after eligibility.
In summary
If you are after speed, the 2 years of Argentina, Peru and Ibero-American Spain are the world records. If you want predictable stability, Canada (3/5) and Germany/France (5) offer more consolidated systems. Europe is rebalancing (Portugal and Sweden tighten, Germany loosened in 2024), while the Gulf countries and the European microstates remain at the restrictive end.
