Argentina put its passport up for sale. Then a court said no.

Argentina has never been a hard country to become a citizen of. Two years of residence, a judge, and a fairly forgiving reading of the rules, and you were Argentine. That old permissiveness is precisely why the current government's move is so odd. Milei has decreed a fast track for investors, waiving even the modest two-year wait. Then a federal court looked at the last version and said no.

So the question is not whether Argentina will sell citizenship. It is whether the courts will let it, and whether a passport handed over by executive fiat is worth carrying.

What the decree actually does

The mechanism sits in Decree 524/2025, published in the Boletín Oficial on 31 July 2025. It builds on an earlier instrument, Decree 366/2025 of 28 May 2025. The headline is simple: a qualifying investor can bypass the traditional two-year residency requirement and naturalise directly.

A new body does the assessing. The Agencia de Programas de Ciudadanía por Inversión, housed under the Economy Ministry, evaluates applications. Migraciones then issues the final resolution within 30 days of receiving the agency's report. The Economy Ministry decides which investments count as "relevant" — the threshold is defined administratively, not in the decree itself, and not in a statute passed by Congress.

That last point is the whole story. The entire framework rests on Citizenship Law 346, a nineteenth-century statute. But the fast-track procedure is delivered by decree, layered on top of the law rather than written into it. In Argentina, that is a fragile place to build.

The court already said no once

On 18 June 2025, a federal appeals court found the citizenship provisions of Decree 366/2025 unconstitutional as applied to the plaintiff. Read that date again. The government issued Decree 524/2025 six weeks after a court struck down the citizenship half of the predecessor decree.

Here is the uncomfortable part. Naturalisation in Argentina is a matter reserved to Congress and to the courts. Citizenship Law 346 gives federal judges the role of granting citizenship. A decree that reroutes that decision to an Economy Ministry agency is, on its face, the executive doing by pen what the constitution assigns to the legislature and the judiciary. The June ruling was narrow — "as applied to the plaintiff" — but the reasoning is not narrow at all. It points straight at the design.

My view: this is not a programme with a legal wrinkle. It is a legal wrinkle with a programme attached.

The quieter tightening you should not miss

Lost in the citizenship noise is a second change that matters more to most relocating families. The same reform tightened ordinary residency.

Permanent residency now requires proof of means. And the absence window before PR lapses was cut from two years to one. That second change is the sharp one. If you hold Argentine PR as a bolt-hole — a base you visit rather than live in — you now have half the runway you had before. Spend more than a year away and the status you paid for and waited for can simply expire.

For the buy-a-base-and-forget-it crowd, that is a real cost, and it has nothing to do with the investor decree at all.

How it compares to the neighbours

Argentina is not the only South American government rewriting residency by executive action this year. It helps to see where the investor route sits.

The contrast with Uruguay is the one to hold in mind. If what you want is a stable, litigation-proof South American citizenship, the boring path — residence, presence, time — still beats the decree. The decree buys speed. Speed is exactly the thing a court can take back.

What a HNW buyer is really being sold

Strip away the announcement and you are buying three things, each with a question mark.

First, a passport whose legal foundation is contested in real time. A citizenship granted under a decree that mirrors one already found unconstitutional is not a settled asset. It is a position in ongoing litigation. If a future court voids the procedure, what happens to grants already made is untested. Nobody can honestly promise you the answer, because the answer does not yet exist.

Second, an administrative discretion dressed as a rule. The Economy Ministry defines what counts as a "relevant" investment. Discretion set by ministry can be changed by ministry. A future administration — and Argentina changes direction hard and often — can redefine the threshold, freeze the agency, or let the whole thing wither. You would be relying on the political weather holding for years.

Third, a genuinely useful base, if you actually live there. This is the part I would not dismiss. Argentina remains, by the ordinary route, one of the more attainable citizenships in the world, and an Argentine passport is a decent travel document with strong regional standing. The residency-then-naturalisation path under Law 346 is real, tested and hard to attack. The decree does not improve that path. It offers to skip it — at the price of standing on ground a court has already cracked.

The realistic play

If you are set on Argentina, the disciplined move is to treat the investor decree as a bonus, not a plan. Structure the underlying investment so it stands on its own merits. Build genuine residence and presence. Let the two-year clock run under the statutory route that no court is going to touch. If the fast track survives the litigation and matures into something reliable, you lose nothing by having a real footprint underneath it. If it is struck down, you still have a lawful, ordinary path to the same passport.

The buyers getting this wrong are the ones treating Decree 524/2025 as a finished product — wiring money against a "relevant investment" definition that a ministry can rewrite and a court can void, on the promise of skipping a wait that was never long to begin with.

The verdict

Argentina put its passport up for sale, and a court said no before the ink on the sequel was dry. Do not buy the fast track as though it were law. It is a decree stacked on a decree that has already been ruled unconstitutional as applied, delivering a decision the constitution reserves to Congress and the judiciary. As a standalone citizenship product for a wealthy buyer, it is speculative — you are funding a legal position, not acquiring a settled status.

But the country underneath the noise is still worth a serious look. The ordinary residence-to-naturalisation route under Law 346 is one of the most attainable in the hemisphere, and it is durable precisely because it is statutory. Take that path. Watch the litigation from a safe distance. And if you already hold Argentine PR as a dormant base, note the change that got no headlines: your status now lapses after one year away, not two. That, more than the passport-for-investment theatre, is the reform that will actually catch people out.
