Citizenship by Investment for Vietnamese Citizens

If you are a Vietnamese citizen weighing a second passport, the first question is not cost or passport strength — it is whether Vietnam will let you keep your nationality. This guide to citizenship by investment for Vietnamese citizens puts that question first, because Vietnam follows a single-nationality principle and no honest advisor should bury it. We explain what the law says, what changed in 2025, why the outcome for an existing citizen is not guaranteed, and why a residency-by-investment route often makes more sense for Vietnamese families. This is general information, not legal or tax advice. Your nationality position must be confirmed with qualified Vietnamese counsel.

Vietnam's Single-Nationality Principle: Start Here

Vietnam's Law on Nationality is built on a single-nationality principle: the state recognises that its citizens generally hold one nationality, Vietnamese. This is different from countries such as Canada, the United Kingdom or Australia, which openly allow dual citizenship. It does not mean dual nationality is impossible in every case, but it does mean you cannot assume, as a Vietnamese citizen, that acquiring a second citizenship is automatically compatible with keeping your first. Nationality matters are administered under the authority of the Ministry of Justice of Vietnam, and the detail matters, so treat this page as the starting point for a conversation with counsel, not a ruling on your own case.

What the 2025 Law Change Did — and Did Not Do

In 2025 Vietnam amended its Law on Nationality (Law No. 79/2025, effective 1 July 2025). It is important to read this accurately, because it has been widely misreported. The amendment mainly helps people naturalising into Vietnam — and those restoring Vietnamese nationality — by allowing them, in defined circumstances and with Presidential approval, to retain a foreign nationality. What it did not do is open blanket dual nationality for Vietnamese citizens who go on to acquire a foreign passport. In other words, the change loosened the rules at the point of entering Vietnamese nationality, not at the point of an existing Vietnamese citizen taking a second one. Anyone citing the 2025 reform as proof that you can freely hold two passports is overstating it.

What It Means If You Acquire a Second Citizenship

Here is the honest position, stated plainly. Vietnamese law does not automatically strip your nationality the moment you acquire another one, so retaining Vietnamese citizenship after obtaining a second citizenship is generally possible — but it is not explicitly codified or guaranteed. That uncertainty is precisely why we will not tell you, as some marketers do, that you will definitely keep your Vietnamese nationality. The outcome can depend on your specific circumstances and on how the authorities apply the law. Before you pursue a second citizenship, this exact point must be checked with qualified Vietnamese legal counsel for your situation. If certainty matters to you, there is a cleaner route, which we turn to next.

The Route That Sidesteps the Question: Residency by Investment

The nationality question only arises because a second citizenship is involved. A residency by investment programme — a golden visa — is not a second citizenship, so taking one does not put your Vietnamese nationality in question at all. You keep your Vietnamese passport and simply add the legal right to live in, and travel from, another country. For many Vietnamese families this is the more comfortable answer: it delivers a European or Gulf base, strong mobility and an eventual (much later) citizenship option, without forcing an immediate decision about your Vietnamese nationality today.

Golden-Visa Options for Vietnamese Investors

Three residency programmes are the most relevant. The Portugal Golden Visa and Greece Golden Visa give you an EU foothold with light physical-presence requirements, while the UAE Golden Visa offers a tax-free, ten-year residency in Dubai or Abu Dhabi. None of these is a “passport for sale”: they grant residency, and any citizenship comes only years later, if at all. The figures below are guide figures for 2026.

Portugal's residency and citizenship framework is administered by the Agency for Integration, Migration and Asylum (AIMA), and the UAE sets out its Golden Visa criteria on the official UAE Government portal. Note the honest caveats: the Portuguese citizenship timeline is ten years, not five, and the UAE Golden Visa never leads to an Emirati passport.

If a Caribbean Passport Still Appeals

Some Vietnamese investors will still prefer a full second citizenship for the mobility a Vietnamese passport (visa-free to only around 48 destinations) cannot match. A Caribbean passport reaches well over 140 destinations, usually including the United Kingdom and the European Schengen Area, and the Caribbean citizenship programs start from around US$200,000. That is a legitimate goal — but for a Vietnamese citizen it brings us straight back to the nationality question, so it should only be pursued after you have confirmed your position with Vietnamese counsel. We will not paper over that step.

Timelines, Due Diligence and Costs

Golden visas typically grant residency within a few months of a complete file; Caribbean citizenships realistically take from around five months (St Kitts and Nevis) to roughly nine to eighteen months (St Lucia), all now involving an interview and biometrics introduced across 2023–24. Every route requires a documented, lawful source of funds, and honesty in that file is the fastest way through vetting. Program terms and thresholds change; confirm current figures on a call.

Speak to Qualified Advisors

For a Vietnamese family, the smart sequence is simple: settle the nationality question first, then choose the route. If keeping your Vietnamese citizenship with certainty matters most, a residency route is usually the better fit; if outright mobility matters more, a Caribbean passport can be right — but only after Vietnamese legal advice, and never on a marketer's promise that you will “keep” your nationality.
