El Salvador has turned, in a short time, into a country where a second passport comes within reach, and on that question it now overtakes its better-known neighbour to the south, Costa Rica. I am a realist, not a salesman, and the honest assessment is this: El Salvador allows naturalisation after five years of lawful residence and accepts dual citizenship, so El Salvador itself does not ask you to give up the passport you hold today. For certain nationalities it is even much faster. It pays to set expectations correctly, though: for most people who move there, residence with its light presence requirement of 90 days a year is the foundation that really matters, and citizenship is an optional later step. Because El Salvador combines a manageable timeline with dual citizenship and, thanks to the low presence requirement, is easy to reach in practice, naturalisation here is more attractive than in many neighbouring countries, especially if you want a second passport as a safeguard in the spirit of flag theory.
El Salvador's route: naturalisation after five years
The standard route to Salvadoran citizenship is naturalisation. If you can show five years of lawful residence in El Salvador, temporary and definitive residence counted together, you can apply for naturalisation; at the time of the application you need definitive residence. That period is moderate by international standards and, in the Central American context, shorter than in Costa Rica, where naturalisation takes seven years. Thanks to the 90-day rule of 2026, you do not have to live in the country continuously during that time: over five years, the minimum presence adds up to only around 450 days. The requirements are manageable: legal age, basic Spanish and a simple naturalisation test on the geography and history of El Salvador in Spanish, a clean criminal record and proof of financial solvency. You also have to show a certain social or economic tie to the country. As documents you will need, among other things, an apostilled and translated birth certificate, a criminal record certificate, proof of solvency and a copy of your passport, with every foreign document apostilled and translated into Spanish. An experienced local lawyer is a real help, because they prepare the documents, represent you before the authorities and steer the process, especially as the detailed rules have changed several times recently.
The fast track for certain nationalities
An important special case: if you hold the nationality of Spain or of a Spanish-speaking American country, even as a second passport, the wait shrinks to one year of definitive residence. If you happen to hold such a second passport, for example through descent or an earlier naturalisation, that is a remarkable shortcut. Nationals of the neighbouring Central American countries also benefit from easier rules. This preference for the Hispanic world is widespread in Latin America and can shape your planning considerably. If you have a Spanish, Argentine or Mexican passport, for example, build that advantage into your strategy, because it shortens the road to a Salvadoran passport dramatically. For most applicants without such a second passport, the regular five-year period applies, which the light presence rules make easy to meet.
How Costa Rica compares
Costa Rica is the longer road. Costa Rica requires seven years of official residence, counted from your first residence status with temporary residence included; for Central and Latin Americans and for Spaniards by birth, the period is five years. The crucial difference is in the presence rules: in Costa Rica, an absence of more than three months in principle resets the naturalisation count, while keeping residence itself only requires at least one entry a year. El Salvador's 90 days a year therefore make it much easier to reach a passport while still travelling, whereas Costa Rica effectively expects you to live there for the whole period. Costa Rica also accepts dual citizenship, so on that point the two are equal. The details of the Costa Rican route are in my article on Costa Rican citizenship.
Dual citizenship: El Salvador allows it
Good news: El Salvador accepts dual citizenship. If you naturalise, you do not have to give up your existing nationality, and Salvadorans who take another nationality do not lose theirs. There is one Salvadoran peculiarity you should know about, though: for the application, El Salvador requires a certificate from your country of origin confirming that it allows dual citizenship. This certificate is usually issued by your home country's embassy or consulate, and it is a good reason to settle the question of multiple nationality early and bindingly anyway. Whether you may keep your current citizenship is decided not by El Salvador but by your home country. This distinction matters: even if El Salvador offers dual citizenship in principle, whether you can actually hold both depends on your home country's rules. Some countries allow dual citizenship without restriction, some require a permit that must be granted before you acquire the new nationality, and some withdraw citizenship automatically when you naturalise elsewhere. So always settle the question from your home country's point of view, and before you naturalise. If keeping your current passport is uncertain, residence on its own already brings most of the practical rights and the full tax exemption of foreign income.
The Freedom Visa: an investor route
Besides the classic route through residence, El Salvador has created an unusual second route. With the Freedom Visa, the country offers wealthy investors accelerated access to residence and, in time, to citizenship in exchange for a substantial investment. With it, El Salvador deliberately positions itself as a magnet for international crypto investors looking for a second passport. Because of the size of the investment, this route is only relevant to a small, very wealthy group, but a complete overview of the options has to include it. It underlines El Salvador's general direction: under Bukele, the country presents itself as open, investor-friendly and crypto-friendly and uses programmes like this to attract international capital. For the typical mover, though, the regular route through residence and the five-year period remains the realistic one.
The passport and its advantages
Why go to the trouble at all? As a Salvadoran citizen you enjoy full political rights, unrestricted access to the labour market and the security of no longer depending on residence renewals. Especially in a country whose residence rules have changed several times recently, the permanence of citizenship is a value in itself, because it makes you independent of future rule changes. Unlike residence, which is tied to conditions, citizenship cannot be withdrawn on those grounds. A second passport is also always a safeguard in the spirit of flag theory, an extra pillar in case circumstances in your home country change. And because El Salvador allows dual citizenship, you add this passport to the one you already have rather than swapping it. If your home passport is already strong, the value lies less in travel freedom than in diversification, full political participation and permanent, unconditional roots in your country of residence. The presence and renewal requirements of residence fall away completely with citizenship, which is valuable for globally mobile people and their families.
The biggest misconception: citizenship is not a tax question
And now the point most guides stay silent about. Salvadoran citizenship does not change your tax position compared with residence. Your tax liability is decided not by your passport but by where your tax residence is, and El Salvador's big advantage, the exemption of foreign income since Decree 969 of 2024, applies from the moment you are resident, not only once you hold the passport. Anyone who believes the passport brings tax advantages is mixing up two separate things. El Salvador taxes by residence and the source of income, not by nationality, unlike the United States, for example. The same holds in Costa Rica, which also taxes territorially, so foreign income stays untaxed there with a residence permit alone. Naturalisation is therefore a question of belonging, political rights and long-term security, not of tax planning. One difference does matter on the reporting side: Costa Rica takes part in the Common Reporting Standard (CRS), El Salvador does not.
Your departure from your home country needs to be looked at just as separately. Moving to El Salvador or Costa Rica does not, on its own, end your tax residence at home, and whether leaving triggers an exit tax on company shares or other assets depends on where you come from, regardless of whether or when you later take a new passport:
Citizenship, tax residence and the tax consequences of leaving home are three separate projects, and each needs its own planning. If you keep them apart, you avoid the typical mistakes and can treat citizenship as what it is: a valuable but optional building block at the end of a deliberately chosen path to El Salvador.
