"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, shortest published processing time first:
- Vanuatu — a published processing time of one to two months, fully remote. The honest catch: Vanuatu citizens need a Schengen visa — the EU suspended the waiver in 2023 and moved Vanuatu to its visa-required list in 2025
- Grenada — a published processing time of three to four months from submission, no visit required, and the only Caribbean citizenship program with a US E-2 treaty (the US adds a three-year domicile condition for citizenship obtained by investment, so US counsel confirms each case)
- St. Kitts & Nevis — the industry's benchmark since 1984; the Citizenship Unit says it generally decides within four to six months, no visit required
- Dominica and St. Lucia — both applied for remotely
- Türkiye — a property-based route with a single biometrics visit; there is no fixed published processing time, and E-2 treaty access carries the same US three-year domicile condition for citizenship by investment
Easiest long-term residence: the UAE
If the goal is a base rather than a nationality, the UAE Golden Visa is one of the simplest options: a self-sponsored residence — 10 years on the real-estate route — 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 favorite for its five-year path to naturalization, 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 naturalization 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 — naturalization 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 naturalize, 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, summarized
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.
