"Easiest" is doing a lot of work in that question. The honest answer depends on three things: the passport you hold today, the capital you can commit, and how much time you're willing to give it. What follows is how the options actually rank in 2026 — including the catches most lists leave out.
What "easy" actually means
- Objective, written criteria — you either qualify or you don't, with no discretionary interview to fail
- A remote process — no relocation, and ideally no visit, before approval
- Little or no physical-presence requirement afterwards
- A predictable timeline measured in months, not years
- Family included in one application
Easiest of all: citizenship by investment
For families with capital, the citizenship-by-investment programs are the most predictable route to a second nationality anywhere — because ease is their design goal. The current field, fastest first:
- Vanuatu — the fastest citizenship in the world, routinely one to two months, fully remote. The honest catch: no visa-free Schengen access since the EU suspended its waiver
- Grenada — approval in roughly three months, no visit required, and the only Caribbean program whose citizens are eligible for the US E-2 investor visa route
- St. Kitts & Nevis — the industry's benchmark since 1984; four to six months, no visit required
- Dominica and St. Lucia — the most accessible entry points to Caribbean citizenship, both remote
- Turkey — a property-based route of four to eight months with a single biometrics visit, and E-2 treaty eligibility
Easiest long-term residence: the UAE
If the goal is a base rather than a nationality, nothing currently beats the UAE Golden Visa for speed and simplicity: a 10-year, self-sponsored residence processed in weeks, with no minimum stay to keep it valid. It is residency, not citizenship — Emirati citizenship cannot be acquired by investment — which is exactly why many residents pair it with one of the programs above.
Europe: easy residence, slower citizenship — and Portugal just changed
Europe's golden visas make residence straightforward, but citizenship there is a long game — and it lengthened in 2026. Portugal, long the favourite for its five-year path to naturalisation, now requires seven years of legal residence for nationals of Portuguese-speaking countries and ten years for everyone else, for applications filed from 19 May 2026 — counted from the issue of the first residence permit, with new language and civic requirements. Many guides still cite the old five-year rule; planning on it today would be a mistake. Greece's golden visa remains an easy residence with no minimum stay, but naturalisation there means seven years of genuine residence and a language exam. Malta's investment route grants permanent residence, not a citizenship track.
Frequently named "easy" — with the caveats attached
- Argentina — naturalisation is constitutionally possible after two years of residence, but it runs through the courts, requires genuine presence, and timelines stretch well beyond the headline
- Paraguay — permanent residence is inexpensive, but citizenship requires roughly three years of real residence and is not the rubber stamp some blogs suggest
- Ireland — five years of genuine residence to naturalise, with no investment shortcut to citizenship at all
Rules in this space change quickly — Portugal's 2026 reform is the proof — so treat any list, including this one, as a starting point to verify rather than a promise.
The honest ranking, summarised
If you have capital and want a second nationality soon: the Caribbean or Vanuatu, eyes open about travel access. If you want speed to a world-class base: the UAE. If you want Europe: commit to the residence years and start the clock now — it only got longer. The right answer is personal, and reaching it takes one conversation, not another list.
