Do I lose my current citizenship if I get a second one?

A straight answer for Caribbean and US-bound investors

The short version: usually, no.

You don't have to give up your original passport to take a Grenadian one.

The longer version has a few moving parts worth understanding before you wire any money, and the rules have changed enough in the last 24 months that a lot of older articles online are now wrong.

At Tandem, we'll walk through what dual citizenship actually is, why Grenada is the Caribbean program we recommend most often for clients with US ambitions, and what the 2024 Caribbean Memorandum of Agreement and the AMIGOS Act mean for you in practice.

If at any point you'd rather just have the conversation, Talk to Tandem and we'll start to work through your specific situation in 30 minutes.

How dual citizenship actually works in 2026

Dual citizenship just means you legally hold passports from 2 countries at the same time. Whether that's allowed comes down to 2 questions: does your home country permit it, and does the country you're naturalising into require you to drop the original?

For the US Caribbean corridor, both answers are friendly.

The United States does not require you to choose. American citizens can naturalise elsewhere without putting their US citizenship at risk, and the US has no formal requiremenst when you pick up a Grenadian passport. The State Department says it plainly on its Dual Nationality page: a US citizen "may naturalize in a foreign state without any risk to their U.S. citizenship." USA.gov repeats the same thing in plainer English.

Grenada, Antigua, St. Kitts, Dominica, and St. Lucia were all designed around dual nationality. That's the entire point of a citizenship by investment program. These countries want global capital and global talent, and forcing renunciation would defeat the purpose.

There's a persistent fear we hear on intake calls that the act of receiving a new passport somehow auto-cancels the old one. It doesn't. The only countries where this is a genuine problem are the handful that explicitly forbid dual nationality outright. For clients from those jurisdictions, we address each situation individually on its on merits and advise accordingly.

Why Grenada is the right anchor for US access

If your second passport is partly about getting into the US to start a business, to put your children in school, to have an actual fallback you can use, rather than just admire, Grenada is the only Caribbean program that gets you there.

Grenada has held an E2 Treaty with the United States since 1989.

Once you're a Grenadian citizen, you're eligible to apply for the E2 Treaty Investor Visa: a non-immigrant visa that lets you live in the US to operate a business you've invested in.

Your spouse can work anywhere in the country.

Your kids under 21 can attend school.

The visa is renewable indefinitely as long as the underlying business stays active.

The US Department of State and USCIS both publish the requirements in detail; they're worth reading before any consultation.

None of the other 4 Caribbean CBI countries can give you this. That's the differentiator, and it's why the Grenadian passport tends to cost more in opportunity terms than its sticker price suggests. We cover it in more depth on our CBI Explained page.

The AMIGOS Act caveat

This is the part most agents either skip or fudge. In December 2022, the US passed the AMIGOS Act as part of the National Defense Authorization Act.

The relevant provision: if you obtained citizenship of a treaty country through "financial investment," you must have been domiciled there for a continuous three-year period before applying for an E2 visa.

Two things matter here. First, "domicile" is a common-law concept, not a day-count. It means Grenada must be your settled home with genuine ties (a residence, financial activity, real life on the island), but it isn't a strict 183-days-a-year residency rule.

Grenadian counsel routinely issue domicile opinions for E2 applicants based on the totality of those ties. Second, there's a spousal route through the Grenadian Constitution that, in some cases, lets a registered spouse skip the three-year clock. We work this angle case-by-case with US immigration counsel.

So, can you still go from Grenadian CBI to a US E2 visa?

Yes. If you want a candid read on whether your timeline is workable, Talk to Tandem.

Will you actually lose your current passport?

For US citizens, the process is genuinely uneventful. You don't need permission, you don't need to declare anything in advance, and don’t need to relinquish your US citizenship

For everyone else, the question is just whether your home country has a no-dual-citizenship rule. If it does, we tell you up front and we either find a workaround.

Grenada handles the naturalisation process discreetly. They don't issue press releases about new citizens, and they don't notify your home government that you've applied and they don’t publish names

What the 2024 MoA and the 2026 reforms actually say

The Caribbean CBI landscape changed in March 2024, when all 5 OECS countries (Antigua and Barbuda, Dominica, Grenada, St. Kitts and Nevis, and St. Lucia) signed a Memorandum of Agreement, with the changes happening later that year:

A floor of US $200,000 on minimum CBI contributions across all 5 countries. No more discounting, no more side rebates, no more cash-back arrangements. Grenada landed at $235,000 for a family of up to four on the donation route, and $270,000 on the real estate route.

Mandatory in-person or video interviews for adult applicants. Enhanced background checks across every jurisdiction the applicants have lived in over the past 10 years.

A separate, later agreement signed in September 2025 created the Eastern Caribbean Citizenship by Investment Regulatory Authority (ECCIRA), a unified regional regulator. Under that framework:

• New citizens were to spend a minimum of 30 days in their CBI country within the first five years post-citizenship (cumulative, not consecutive).
• Passports would issue for an initial 5 year term, renewable for a full 10 years on compliance verification.
• Penalties for non-compliance could reach 10% of the original investment.

The 30 day rule was originally targeted for April to June 2026 rollout.

After St. Lucia's December 2025 general election, the legislative pipeline needed to bring the rules into force across all five countries was paused.

As of May 2026, the residency obligation is not yet active. We expect it to come online later in 2026 and we're advising clients to plan as if it will.

30 days over 5 years is not a hardship, and as you'll see in a moment, it actually helps you.

We track every IMA circular and update on our News page so clients aren't relying on month-old information.

How the residency rule and the AMIGOS Act work in your favour

If you're using the Grenada CBI program as a stepping stone to a US E2 visa, you need to build a domicile case anyway.

The 30-day Caribbean rule, when it activates, is the floor, not the ceiling.

Most clients building a real E2 case spend considerably more time on the island, hold property here, open local accounts, and treat their Grenadian life as a real one rather than a paperwork fiction.

A number of approved developments even offer complementary annual accommodations at their resorts to approved investors.

The State Department officers asking the questions are not naive. They want to see ties.

This is also where having an advisor with offices in St. George's matters more than having one with a glass tower in London or Dubai.

We can help you set up a Grenada Tax ID, find a long term rental, or beachfront pied á terre introduce you to local banking, and document your visits in a way that supports a future domicile opinion.

None of this is sold separately as theatre. It's just what serious preparation looks like.

The investment options: NTF or real estate

Two routes, both real, with different trade offs.

National Transformation Fund (NTF) donation. $235,000 for a single applicant or family of up to four. Non-refundable. Goes into Grenada's development fund for tourism, infrastructure, and education projects. The cleanest, fastest route, typically 3 to 6 months from submission to passport.

Approved real estate. Starts at $270,000 for shared ownership in a government approved tourism project (resorts, villas, branded hotels), or $350,000 for non hospitality development (apartments/condos) both with with a 5 year minimum hold before resale or divestment. Some clients receive rental yield during the holding period; others don't, this is dependent on the project. The capital is preservable rather than gone.

For clients who want a physical nexus on the island, particularly clients with E2 ambitions, we tend to recommend the real estate route. Owning property is one of the cleanest pieces of evidence of genuine connection to Grenada.

For clients who just want citizenship and don't care about Grenadian real estate exposure, NTF is the right call.

A look at the projects we currently work with, including One True Blue Beach, Hideaway True Blue, the InterContinental Grenada Resort, and Silversands Villas, lives on our Projects page.

Every one of them is approved by the IMA. Tandem will not promote unapproved developments.

Family inclusion: who can come with you

The Grenadian program is unusually generous on dependents. In a single application you can include:

• Your spouse.
• Children under 30, provided they're financially dependent on you. (No university enrolment requirement, though that helps demonstrate dependency.)
• Parents and grandparents of any age, provided they're dependent on you. They don't need to live with you.
• Unmarried siblings 18 and older, provided they have no children of their own. (Additional government fees apply).

Want a written estimate for your specific household? Talk to Tandem and we'll have it back to you within a day.

What you actually get with the citizenship and passport

Visa free or visa on arrival access to over 145 destinations as of 2026. The headline ones:

• The 27 Schengen states, for 90 days in any 180 day period. The EU's pre-travel authorisation system, ETIAS, is scheduled to launch in Q4 2026 (€20 fee, valid for 3 years). It's a 5 minute online application, not a visa.
• The UK, for up to 6 months. Since January 8, 2025, Grenadians have needed a UK Electronic Travel Authorisation (ETA) before flying. £20, valid for 2 years.
• China, for 30 days visa-free.
• Russia, Singapore, Brazil, Hong Kong and most of the Commonwealth.

The US is not on the visa free list, but Grenadian citizens can apply for a 10 year B1/B2 tourist visa, and as discussed, the E2 route is what makes Grenada different.

For tax planning: Grenada does not tax foreign source income, dividends earned outside Grenada, capital gains, inheritance, or wealth.

At Tandem, we’re not your tax advisor, and you should retain proper international tax counsel before making decisions on this basis, but the framework is favourable.

Where to research this yourself before you talk to anyone

Good advisors don't try to be your only source. These are the official, authoritative pages we send clients to before our first call:

• Investment Migration Agency (IMA) Grenada. The Grenadian government authority that runs the program. The Legal and Finance and Reports and Statistics sections are particularly worth reading.
• US Department of State, Treaty Trader & Treaty Investor Visa. The consular side rules for E2 applications.
• USCIS, E-2 Treaty Investors. The immigration services side rules, including how E2 status works for those already inside the US.
• US Department of State, Dual Nationality. The official US position on holding 2 passports.
• UK ETA, GOV.UK. The UK Electronic Travel Authorisation portal, the only legitimate place to apply.
• ETIAS, official EU portal. The EU's official ETIAS information page. There are dozens of fake ETIAS sites; this is the real one.

If you want to read questions other clients have asked us, our Frequently Asked Questions section is a reasonable next stop.

What working with Tandem actually looks like

We're based in St. George's the capital of Grenada, not a satellite office, not a call centre or AI bot.

The advantage of that is mostly boring and operational: when the IMA changes a form, we know about it the same day; when a developer's project status shifts, we hear it before the press release; when a client needs a Tax ID set up before their first visit, we can walk it down the street and not wait for an embassy response.

We commit to a 24 hour response standard on client correspondence because the wire-transfer stage of a CBI application is not a moment to be left wondering whether anyone is reading your email. Source-of-funds files are prepared to OECS regional standards, with the assumption that they will be audited. They usually are.

After the passport, we stay involved. Tax ID setup, local address, real estate management, passport renewal at year 5, all of it.

A few things we won't tell you

We won't tell you the AMIGOS Act doesn't matter. It does, and any agent telling you the E2 visa is a 6 month process from CBI signing is selling you something.

We won't tell you the 30 day Caribbean residency rule is permanent dead law. It isn't. It's been postponed, not killed, and we plan as if it's coming.

We won't tell you Grenada is the right answer for everyone. Once we fully understand your reasons for looking at second citizenship, we will guide and advise you in the right direction, even if that isn’t Grenada.

A second passport is a useful thing to have. It's not magic, and the agents who sell it as magic tend to be the ones who can't help when something goes sideways.

If you want to talk
