Argentina citizenship for Brazilians: an honest assessment

Brazil now lets its citizens hold a second nationality freely. But for most Brazilians, Argentina is already open through Mercosur, so the investment route needs a specific reason.

Key facts

  • Since Constitutional Amendment 131 (3 October 2023), a Brazilian no longer loses nationality by acquiring another one.
  • Mobility gain is nil: Brazil 170 destinations (#15), Argentina 169 (#16) on the July 2026 Henley index. Both need a US visa.
  • Brazilians already have a low-cost route: Mercosur residence, then ordinary naturalisation after 2 years.
  • Investment route: US$350,000 non-refundable, or a US$800,000 bond. Applications open in Q4 2026.
  • The legal basis is under appeal at the Supreme Court. See legal status.

Most of our nationality guides start with the passport. For Brazilians, that is the wrong place to start. A Brazilian passport and an Argentine passport open almost the same doors, so the case for Argentina citizenship by investment rests on other things: speed, legal diversification, family planning and a base in a neighbouring country.

This guide is deliberately sceptical. For many Brazilian families, the honest answer is that they do not need to pay US$350,000 for something Mercosur already gives them.

Can a Brazilian hold Argentine citizenship?

Yes, and this is now settled. Constitutional Amendment 131, promulgated on 3 October 2023, rewrote Article 12 §4 of the Brazilian Constitution. A Brazilian now loses nationality in only two cases:

  • a court cancels a naturalisation for fraud or for an attack on the constitutional order; or
  • the person makes an express request to lose Brazilian nationality, unless that would make them stateless.

The old rule, under which acquiring another nationality could cost a Brazilian their own, was repealed. Argentina also allows dual and multiple nationality and does not ask naturalised citizens to renounce their original one. Our dual citizenship guide explains the Argentine side.

The mobility question: little to gain

The table compares the two passports on the destinations that matter most to our readers.

Destination Brazilian passport Argentine passport
Schengen Area Visa-free, 90/180 days Visa-free, 90/180 days
United Kingdom ETA ETA
Japan Visa-free Visa-free
United States Visa required Visa required
Canada Visa, or eTA if you hold a US visa or a recent Canadian visa Same rule
Henley Passport Index, July 2026 170 destinations (#15) 169 destinations (#16)

Argentina is not in the US Visa Waiver Program. It was a member from 1996 to 2002, and a new application has made slow progress. If US access is your goal, an Argentine passport does not solve it today. Read more in our Argentine passport guide.

You may not need the investment route at all

This is the point most sellers of the programme will not make. Brazil and Argentina both apply the Mercosur Residence Agreement, signed in Brasília on 6 December 2002. A Brazilian can obtain temporary residence in Argentina for up to two years and convert it to permanent residence.

Argentine law (Ley 346) then allows ordinary naturalisation after two continuous years of legal residence, through an application to a federal judge. For a Brazilian who is willing to live in Argentina, that route costs a fraction of US$350,000.

There is a further reason to be careful. Two federal courts have ruled against DNU 366/2025, the decree behind the investment route. On 18 June 2026, Chamber III of the federal civil and commercial appeals court (the Volosh case) struck down the parts that give citizenship decisions to Migraciones. On 30 June 2026 the Cámara Nacional Electoral declared the decree unconstitutional and ordered citizenship cases to go before federal electoral judges under Ley 346. The government has appealed to the Supreme Court and says the decree stays in force until the ruling is final. The ordinary residence route does not depend on that decree. Our legal status page tracks the appeal.

When the investment route can make sense for a Brazilian

The programme removes the residence requirement. That has value in a few situations:

  • You will not relocate. Executives and business owners who must stay in São Paulo or abroad cannot meet two years of continuous residence.
  • Time matters. Decreto 524/2025 gives Migraciones 30 business days to decide after the Agency’s report. The full processing time is not yet published, but the design is faster than two years plus a court process.
  • Family structure. One application can cover a spouse and children, at US$100,000 per spouse or adult dependent child (18–25, single, without children) and US$25,000 per minor.
  • Legal diversification. A second nationality held independently of Brazil can matter for estate planning, banking relationships or political-risk planning. Speak to a qualified adviser about whether it achieves anything in your own case.

One thing it does not add: the Spanish shortcut. Spain gives Ibero-American nationals by origin a two-year residence route to Spanish nationality. Naturalised Argentines do not qualify. Brazilians by origin already do.

Tax, reporting and moving the funds

Argentine citizenship does not move your tax home. People naturalised through investment are not treated as Argentine tax residents solely because of the naturalisation. Argentine tax residence follows the normal rules, such as permanent residence.

On the Brazilian side, tax residents are taxed on worldwide income, with a top monthly rate of 27.5%. Law 14.754/2023 requires Brazilian residents to report income from capital invested abroad separately in the annual return, taxed at 15%. A zero-interest bond would not generate income in the ordinary sense, but the reporting position of a US$800,000 holding abroad is a question for your Brazilian accountant.

The programme requires all funds to move through the formal financial system. In practice that means a documented bank transfer from Brazil through an authorised foreign-exchange channel, with the source of funds traceable. Keep the records; the Argentine Agency checks the traceability and legality of funds.

Compliance and documents

  • FATF: Brazil is not on the FATF list of jurisdictions under increased monitoring after the June 2026 plenary.
  • Apostille: Brazil joined the Hague Apostille Convention with effect from 14 August 2016. Argentina is also a party. Brazilian civil and criminal-record documents can therefore be apostilled rather than legalised by a consulate.
  • Due diligence: the official release lists identity checks, source-of-funds traceability, asset analysis, jurisdictional risk, criminal and reputational background, and migration history, aligned with OECD and FATF standards. SIDE, the UIF, the Ministry of Security and the Ministry of the Interior take part.

The cost, in context

Child under 18 US$25,000 each
Official example: couple + 2 minors US$500,000

Government fees, the application portal and post-grant obligations are not published as of 2 October 2026. Our cost guide is updated as details appear.

Is it right for you?

Probably not, if you can spend two years living in Argentina, or if your main aim is easier travel. Mercosur residence and ordinary naturalisation get you the same passport for much less.

Possibly, if you cannot relocate, want a whole family covered in one process, and value a second nationality for planning reasons. Even then, wait for the Supreme Court and for the published fees before you commit funds.

If you want to compare the two routes against your own circumstances, a private briefing is a good next step.

Frequently asked questions

Will I lose Brazilian nationality if I become Argentine?

No. Since Constitutional Amendment 131 of 3 October 2023, a Brazilian loses nationality only by an express request to the Brazilian authorities or by a judicial cancellation of a naturalisation. Acquiring another nationality is no longer a ground for loss.

Does an Argentine passport help a Brazilian travel more?

Hardly. The Henley Passport Index (July 2026) puts the Brazilian passport at 170 visa-free or visa-on-arrival destinations, one more than Argentina's 169. Both passports need a US visa and have the same conditional Canadian eTA rules.

Is there a cheaper way for a Brazilian to become Argentine?

Usually yes. A Brazilian can get Argentine residence under the Mercosur Residence Agreement and apply for ordinary naturalisation after two continuous years of legal residence. The investment route is for people who cannot or will not live in Argentina for two years.

Does Argentine citizenship make me an Argentine tax resident?

Not by itself. People naturalised through investment are not treated as Argentine tax residents solely because of the naturalisation. Brazilian tax residence, with tax on worldwide income, continues until you formally leave Brazil's tax net.
