How fast can you get a second passport in Latin America? The naturalisation periods of all the main countries in 2026, from Argentina's two years (a rule now contested in court) to Colombia's roughly ten, always counted from your first legal residence, plus dual citizenship, MERCOSUR and the truth about what your passport does and does not change for tax.
A second passport is probably the strongest building block of a real Plan B, and Latin America is one of the most attractive regions in the world to get one. The reasons are concrete: short naturalisation periods well below the European standard, near-universal acceptance of dual citizenship, passports that travel well and, with MERCOSUR, a free movement area that opens up a whole continent. But periods and rules differ greatly from country to country, and some of them shifted noticeably in 2026. This overview gives you a straight answer on where you can get a second passport, how fast, and what really matters. One point up front: a passport is a right, not a product, and the fastest routes demand genuine presence.
Why Latin America is so strong for a second passport
Let's start with the basics. In Europe, naturalisation in under five years is practically unknown, and in large parts of Asia it is almost impossible. In Latin America, by contrast, it is the rule, not the exception. Two further strengths add to that. Almost every country in the region allows dual citizenship, so you do not have to give up your old passport as far as the destination is concerned. And nine countries are part of the MERCOSUR Residence Agreement, which gives citizens of the member states the right to live, work and settle anywhere in the bloc, much like EU citizens in Europe. A single South American passport thus becomes the key to half a continent. Hardly any other region of the world bundles speed, dual citizenship and free movement so generously.
The fastest: Argentina and Peru
At the top for speed is Argentina, with just two years of legal residence under Ley 346 of 1869, the shortest standard route in the region, as industry analyses confirm. But the rule is contested in court: since Decree 366/2025 the migration authority requires two years without a single departure; the Cámara Nacional Electoral declared that no-exit version null and void on 30 June 2026, and the case is now before the Supreme Court. The details are in my article on Argentina. Peru also has a two-year route today, but Ley 32421 raises the period to five years as soon as its implementing regulation is published, which was still outstanding on 24 October 2026. Until then, the two-year rule applies. If you are looking for the fastest route in the region and are prepared to be genuinely present, Argentina is the candidate, as long as the courts leave the rule standing, with the added advantage of a strong passport ranked around 15th in the world and MERCOSUR free movement. What matters is building those two years without gaps and with real presence, because that is exactly where many applications fail.
The middle way: Paraguay, Ecuador, Brazil
The middle group holds three very different countries. Paraguay leads to naturalisation after five years (two years of temporary residence, then three years of permanent residence; three years if permanent residence is granted directly), but requires a language test in Spanish or Guaraní, a history test and genuine presence: no more than three months abroad in each of the three years before the application. In return it is the most affordable and most tax-attractive destination. If you are tax-conscious and do not mind genuine presence, Paraguay is often the smartest choice in this group. Ecuador naturalises three years after permanent residency, which comes after 21 months of temporary residence, so just under five years in total, and has a considerably weaker passport. Brazil requires four years of permanent residence as standard, around six with the usual temporary start, and offers one of the strongest passports in the region; the details are in my guide to Brazilian citizenship. Three routes, three profiles: affordable and tax-friendly, dollarised, or a strong passport at the end of a longer road. Which one fits depends less on the period than on how you want to live.
The five-year class: Uruguay, Chile, Mexico, Panama, El Salvador
The largest group naturalises after five years, with important differences. Uruguay counts the time from when you take up residence, not only from when your card is issued, a real advantage. Chile counts from the first temporary residence but requires the Residencia Definitiva at the time of application, and in return offers the strongest passport in the region, with ESTA access to the United States. Mexico counts temporary residence towards the five years. Panama requires five years from permanent residence and, formally, renunciation of your previous nationality, which in practice the country of origin usually ignores. El Salvador adds temporary and permanent residence together and requires permanent residence at the time of application. Five years is longer, but several of these passports are particularly strong or come with tax advantages. Chile and Uruguay in particular combine the longer period with high stability and a very good travel document.
The long road: Costa Rica and Colombia
At the other end are Costa Rica, with seven years from your first residence, reduced to five for citizens of other Ibero-American and Central American states, and Colombia: there the five years only start with the resident visa, which on the usual routes comes after five years on a migrant visa, so around ten years in total. Costa Rica sells not so much a fast passport as the quality of life and stability of a country without an army. If a second passport is your main goal, the region has faster options; but if you want to live in Costa Rica anyway, the longer period is part of a larger, attractive package. Here too, the period alone says little; what decides is the overall mix of lifestyle, tax and passport. If you only look at the number of years, you often end up with a country that does not fit your needs.
What each passport is worth
The waiting period is only half the story; the strength of the passport at the end counts too. The Henley Passport Index ranks the region clearly: Chile leads with around 175 visa-free destinations and its unique US ESTA access, followed by Argentina and Brazil with around 169 to 170 destinations, then Uruguay with about 156 and Mexico with around 155. Paraguay and Panama sit at about 142 to 145, Ecuador well below. Then there is the often underestimated MERCOSUR advantage: an Argentine, Brazilian, Uruguayan or Paraguayan passport opens residence and work rights across the whole South American bloc. So the strongest passport is not automatically the fastest, and the right choice weighs speed, passport strength and free movement against each other. For one person every month saved matters; for another, every extra visa-free country.
The eternal rule: a passport is not a tax status
Now the point I cannot repeat often enough, because it is so often misunderstood. Citizenship does not automatically make you liable to tax. In Latin America, tax liability almost everywhere depends on tax residence, meaning days of presence, centre of life and economic interests, not on your passport, as the tax summaries of the individual countries show. If you hold an Argentine or Brazilian passport but live abroad, you generally owe these countries no tax. That is a fundamental difference from the model of the United States, which taxes its citizens worldwide. In practice: the second passport is a travel and free movement document and a Plan B anchor; the tax question is separate and depends on where you actually live. Keep the two strictly apart and your planning will be sound. I keep seeing people grow afraid of a passport because of this confusion, when it would cost them nothing in tax.
And buying one? Citizenship by investment
A word on the shortcuts people keep asking about. Unlike the Caribbean with its established citizenship-by-investment programmes, mainland Latin America has so far had hardly any genuine routes to buy a passport. Argentina has announced a first such programme by decree, but it is not operational, takes no applications and stands on shaky legal ground. Paraguay's investor route does not shorten citizenship itself but leads faster to permanent residency, from which the regular three-year period then runs. If you are looking for a genuine citizenship you can buy straight away, you will find it in the Caribbean rather than on the mainland, and there the programme's credibility needs careful checking. In South America, the reliable route remains genuine naturalisation through residence.
The most common mistakes
I see three mistakes in second passport planning again and again. First, underestimating the presence requirement: the fast routes such as Argentina or Paraguay demand genuine presence, and if you only want a permit in your back pocket, you lose time or fail. Second, confusing passport and tax, and giving up a passport that costs nothing in tax out of an unfounded fear of tax liability. Third, not checking before you apply whether your own country lets you keep its citizenship when you naturalise elsewhere, and so putting your original passport at risk. Know these three and plan around them, and your second passport becomes a real, lasting gain instead of an expensive disappointment.
Your part: dual citizenship and your departure
Two questions come before everything else. First, dual citizenship: almost all Latin American countries allow it, but whether you keep your original citizenship is decided by your home country's nationality law, not by the destination. Check that before you file the application. Second, your departure: the passport alone does not change your tax position at home. If you genuinely move, you have to end your tax residence properly and check whether leaving triggers an exit tax on company shares or investments. Structure decides, not the destination. What ending your tax residence takes, and whether an exit tax applies, depends on where you come from:
Second passport routes at a glance
Latin America is one of the best regions in the world for a second passport: short periods, accepted dual citizenship, solid passports and MERCOSUR free movement. The range runs from Argentina's two years (contested in court) through the middle way of Paraguay, Ecuador and Brazil (three to six years) and the five-year class to Costa Rica's seven years and Colombia's roughly ten. The right choice depends not only on the period but on passport strength, presence requirements, language, tax and your life plan. And the most important rule remains: a passport is not a tax status, and whether you may keep your original citizenship is the first thing to check. That is exactly the trade-off I work through with my clients before they commit.
