Two names come up again and again when UAE and GCC residents ask about a second passport: the Caribbean and Vanuatu. Both let you become a citizen through investment. Both skip the residency requirement. Past that, they’re quite different, and some of those differences have shifted a lot over the last two years.

So which one fits you? It depends on where you travel, who’s on the application, and how much risk you’re comfortable with. We’ll go through all of it, starting with the basics of holding more than one nationality.

Dual citizenship means you hold two countries’ citizenship at the same time. You’ll also see it called dual nationality or double nationality, and multiple citizenship when it’s more than two. Same idea, different labels. Some people say dual passport, which is just the paper side of it, and a few forms use “dual national citizenship.” They all mean one thing.

Plenty of people want it. A second passport can make travel easier, give you a fallback if things change at home, and open doors for your kids’ schooling or your business. For many people in the Gulf, there’s another reason. A residence visa lasts only as long as the job or the sponsor does. A citizenship doesn’t.

This is the step people skip. Some countries allow dual citizenship freely. Others restrict it, and a few take your citizenship away if you pick up another one voluntarily. India is a well-known example, since it doesn’t recognise dual citizenship. Several Gulf states also restrict it or ask for government permission, so GCC nationals especially need to check their own law first.

The rule that matters is your home country’s, not the Caribbean’s or Vanuatu’s. Both programs let you keep your current nationality. Whether your own government lets you is a separate question, and it’s the first thing we ask on a consultation. Unsure? Talk to a lawyer back home before you pay for anything.

Most people end up on one of four roads. Descent works if a parent or grandparent held another country’s citizenship. Marriage can work too, with a qualifying relationship and some waiting time. Naturalization means living somewhere for years, often five to ten, and then applying. And then there’s investment.

Descent and marriage depend on your family story, and naturalization takes a long time. That leaves investment as the one route you can plan around today.

Second citizenship by investment, usually shortened to CBI, is a government program. You put money into the country, pass due diligence, and become a citizen. No years of residence first. Two groups of countries dominate: five Caribbean islands (Dominica, Antigua & Barbuda, Grenada, Saint Lucia, and St Kitts & Nevis) and Vanuatu in the Pacific.

Every application goes through a licensed agent, and governments turn down applicants who don’t clear the background checks. It isn’t a shop counter. For the full picture on each, read our Caribbean citizenship by investment guide and our Vanuatu citizenship by investment guide.

Caribbean passports open 140 or more destinations, including the UK and the Schengen Area. That’s the big draw. But the Schengen part is now conditional.

At the end of 2025, the EU changed its rules so that running a citizenship by investment program can, by itself, be grounds for suspending visa-free travel. According to Antigua and Barbuda’s government, the European Commission has asked the five Caribbean countries to wind their programs down by June 2028. Any suspension would still need a separate EU decision, and none has been announced. The Commission’s next report is due in December 2026. The US has also tightened some visa rules for Caribbean CBI countries this year, so check your destination against your specific passport.

Vanuatu has already been through this. The UK ended visa-free travel in 2023, and the EU ended it for good in late 2024. What’s left is around 88 destinations on the Henley Passport Index, including Singapore and Hong Kong.

So today, a Caribbean passport gets you further. But if Europe is the main reason you want a second passport, don’t build your plan on any CBI passport. Treat Schengen access as a bonus that could change.

In our experience, both take roughly four to eight months from first call to passport in hand. Vanuatu’s government quotes 30 to 60 days for processing, but the paperwork around it, like attestation and due diligence questions, takes the rest.

The process differs in a few places. Vanuatu requires biometrics from everyone on the application, whatever their age, and its Dubai office takes them. Caribbean requirements vary by country. St Kitts & Nevis, for one, requires biometrics as of 2026.

What Drives the Cost

The two drivers are the same in both programs: how many people are on the application, and which passport you hold now. A bigger family costs more. Adding someone after approval costs more again, so include everyone you might want covered at the start. Some nationalities need heavier checks, which can change the fees or even rule a program out.

We won’t print figures here, since they move. The Caribbean gives you five programs with different structures to shop between, while Vanuatu is a single program. Ask us for current numbers for your family and your passport.

The Caribbean tends to suit you if:

• Travel access today matters, especially the UK
• You have a large family, or US business plans (Grenada has a path to the US E-2 Investor Visa)
• You’d like a choice of programs and routes, including real estate or a bond option
• You can live with the chance that Schengen access changes

Vanuatu tends to suit you if:

• Speed and simplicity come first
• Most of your travel and business is in Asia and the Pacific
• You want one clear program, with biometrics done in Dubai
• Europe isn’t why you’re doing this

There’s a third option too. If your real goal is living or studying in Europe, a CBI passport isn’t the right tool, but we also help with residency in Portugal, Spain, Malta and Greece. A residency permit, with a route to citizenship later, rests on firmer ground. Our European residency guide covers each one. And if your home country doesn’t allow dual nationality, sort that out before anything else.

Planning around Schengen access is the big one. It exists for Caribbean passports today, but it isn’t guaranteed.

Assuming your home country allows dual citizenship catches people out too. Check first, because losing your original citizenship is a steep price.

Choosing on speed alone is another trap. Both programs take months, and a few weeks’ difference rarely matters more than where you’ll actually use the passport.

Then there’s budgeting for one person. Families add up fast, and adding people late costs more.

Unlicensed agents cause real trouble. Both programs require a designated or authorized agent.

And attestation takes longer than people expect from the UAE and GCC side. Start it early.
