A New Zealand passport clears roughly 190 countries visa-free; a weak one clears barely a third of that. For a nomad holding the wrong passport, a second one isn't vanity, it's logistics. It's also the fastest-changing part of this industry: two of the routes nomads ask us about most aren't what most articles still claim they are.

Key Numbers to Know (2026)

• Caribbean CBI (typical range): USD $200,000–$350,000 donation, or USD $400,000+ real estate

• Malta "Naturalisation for Exceptional Services": discontinued as a purchasable route in 2025 (see below)

• Vanuatu CBI: USD $130,000+, fastest processing, now materially reduced value (see below)

• Portugal Golden Visa (residency-then-citizenship): €500,000+ various investments; 10-year residency requirement before citizenship eligibility (7 years for CPLP/EU citizens)

• Turkey CBI: USD $400,000+ real estate

• Ancestry citizenship: varies widely, via Italy, Ireland, Poland, Germany, and others by bloodline

• Standard naturalisation: typically 5–10 years of residency

• Second-passport visa-free access: varies enormously depending on the issuing country

Why Nomads Consider a Second Passport

A weak home passport turns every border into friction: visas to arrange, appointments to book, fees to pay before you've even started a trip a strong passport would let you take on the way to the airport. Some citizenships, EU ones especially, open residency options across dozens of countries rather than one. For anyone whose home country carries real political or economic instability, a second citizenship functions as insurance rather than upgrade. And for non-US citizens it can be the route out of a citizenship they no longer want to owe tax to. US citizens face a separate, harder problem: renunciation, which carries its own exit-tax complexity, covered in a companion piece.

The Routes

• Caribbean CBI (St Kitts & Nevis, Dominica, Antigua & Barbuda, Grenada, St Lucia)
  Typical cost: $200K+ donation or $400K+ real estate
  Timeline: 3–9 months
  Key caveat (2026): Dominica and St Lucia are UK visa nationals; no UK visa-free access. Dominica and Antigua & Barbuda are subject to a new US visa-bond requirement (USD $5,000–$15,000) from 21 January 2026.

• Malta "Naturalisation for Exceptional Services"
  Typical cost: Not purchasable
  Timeline: N/A
  Key caveat (2026): Ruled unlawful by the CJEU in April 2025 and formally discontinued in July 2025, replaced by a discretionary, non-purchasable route. Not available at any price.

• Vanuatu CBI
  Typical cost: $130K+
  Timeline: Weeks (fastest)
  Key caveat (2026): EU/Schengen visa-free access was suspended and made permanent in February 2025. Also a UK visa national, so no UK visa-free access either.

• Turkey CBI
  Typical cost: $400K+ real estate
  Timeline: Several months
  Key caveat (2026): Strong regional access; moderate global reach.

• Portugal Golden Visa → citizenship
  Typical cost: €500K+ various investments
  Timeline: 10-year residency before citizenship (7 years CPLP/EU)
  Key caveat (2026): Cheaper per year than CBI but far slower; a transition rule preserves the old 5-year path only for applications filed before it changed.

• Naturalisation (standard)
  Typical cost: Cost of living in the country
  Timeline: 5–10 years' residency
  Key caveat (2026): Requires genuine integration, not just presence.

• Ancestry (jus sanguinis)
  Typical cost: Legal and document fees only
  Timeline: Months to a few years, tracing-dependent
  Key caveat (2026): Italy, Ireland (grandparent rule), Poland, and others; effectively free if you can prove the bloodline.

• Marriage
  Typical cost: Varies
  Timeline: Varies
  Key caveat (2026): Accelerated naturalisation via marriage to a citizen; timeframe and requirements differ widely by country.

The Cost-Benefit Framework

For strong-passport nomads, holders of US, UK, most EU, Canadian, or Australian passports, a second one is usually a luxury: nice to have, rarely essential. For weaker-passport nomads it can be transformative for mobility alone. For anyone based in a politically uncertain jurisdiction, the insurance value can matter more than the travel value. And for US citizens who actually want to renounce, a second citizenship isn't optional; you can't renounce into statelessness, so CBI is often the fastest way to clear that prerequisite.

Passport Tiers, and Why Most Upgrades Don't Matter

• 1
  Visa-free access: 180+ destinations
  Examples: Singapore, Japan, most Western EU, US, UK, Canada, Australia

• 2
  Visa-free access: 130–180 destinations
  Examples: Most Caribbean CBI passports, Malta, Cyprus, Portugal, Poland, other EU

• 3
  Visa-free access: 80–130 destinations
  Examples: Turkey; Vanuatu, now nearer the bottom of this band after losing EU and UK access

• 4
  Visa-free access: Below 80 destinations
  Examples: Weaker passports generally

For a Tier 1 holder, adding a Tier 2 passport barely moves the needle, and adding another Tier 1 passport is close to meaningless for travel purposes. For a Tier 3 or 4 holder, moving into Tier 2 is genuinely transformative. Know which move you're actually making before you pay six figures for it.

Where This Interacts With Tax

Second citizenship doesn't automatically change your tax residency; that's a separate legal question entirely. US citizens with a second citizenship can renounce US citizenship, but covered expatriates face an exit tax on the way out. Non-US citizens generally have a simpler path to shedding home-country obligations. Some countries allow multiple citizenships freely, while others require formally renouncing the previous one, so check the rules in both directions before you commit to either.

Deciding If You Need One

A second passport is a five- or six-figure decision, and increasingly a fast-moving one, as Malta's collapsed programme and Vanuatu's lost access both show. Tell us your current passport and what you're actually trying to solve, mobility, insurance, or an exit, and we'll tell you honestly which route, if any, is worth it.
