Fastest paths from residency to citizenship in 2026

The routes we track fall into three buckets. Citizenship by investment (CBI) programs require no prior residency — you contribute or invest, pass due diligence, and receive a passport. Citizenship by descent programs recognize that you may already hold citizenship through a qualifying ancestor, requiring registration or confirmation rather than naturalization. Residency-to-citizenship tracks require you to live in a country for a set period before applying to naturalize.

The fastest routes tracked here are all CBI or descent-based — none require years of residency first. If you're exploring broader visa and residency options, the free visa & residency finder covers the full spectrum, and second passports for Americans, mapped focuses on the US-specific angles.

CBI programs are the only legal routes where you can hold a new passport without ever living in the issuing country. Eight programs in the data meet that description. Here's what separates them.

**Vanuatu** is the speed leader: a donation of around $130,000 to the Development Support Program can produce citizenship in as little as 1–2 months, with no residence requirement. The EU suspension of visa-free access is a real trade-off to understand before applying. Full details at Vanuatu: every visa & residency route.

**Nauru** relaunched its Economic & Climate Resilience Citizenship program in 2024. A single-applicant donation starts from around $105,000, with citizenship in roughly 3–4 months and no residence needed. It's a newer program with a smaller visa-free footprint — around 119 destinations — and evolving international acceptance. Verify current travel access before relying on it.

**The five Caribbean programs** — Dominica, Antigua and Barbuda, Grenada, St Lucia, and St Kitts and Nevis — all process in roughly 4–6 months (Dominica up to 9). They participate in a 2024 regional pricing accord setting a $200,000 harmonized floor for donation routes. Donation minimums run from $200,000 (Dominica) to $250,000 (St Kitts). All offer Schengen visa-free travel. Two stand out for specific reasons: Grenada citizens can apply for the US E-2 treaty-investor visa, as can Antigua and Barbuda — making both popular with US-bound entrepreneurs. Antigua requires a 5-day physical visit within the first 5 years; the others have no visit requirement at all.

**Turkey** sits at a higher investment threshold — $400,000 in real estate held for 3 years, or $500,000 in a bank deposit, fixed capital, or government bonds — but delivers citizenship in roughly 6–12 months with no language test, no minimum stay, and no residency requirement. Turkey allows dual citizenship and grants E-2 treaty-investor visa eligibility for US purposes. Full details at Turkey: every visa & residency route.

**Egypt** offers a $250,000 non-refundable contribution to the state treasury as its fastest route, with citizenship in roughly 6–9 months. Alternatives include $300,000 in property, a $350,000 business investment, or a $500,000 bank deposit. Like Turkey and Grenada, it grants US E-2 visa eligibility — a draw for applicants who want a path to the US without naturalization.

If an ancestor holds the key, descent-based citizenship costs little beyond legal and document fees. The catch is proving the chain — and knowing where it breaks.

**Ireland** is the most straightforward EU descent route for Americans. If a grandparent was born on the island of Ireland, registering on the Foreign Births Register makes you an Irish — and EU — citizen. No language test, no residence, no investment. Processing runs roughly 9–12+ months. Beyond grandparent level, each generation must have registered before the next was born to keep the chain alive.

**Poland's** route is technically a confirmation that you already hold citizenship — no generational cap if the documentary chain holds. The critical pitfall: the Polish ancestor must not have lost Polish citizenship, for example by naturalizing abroad or serving in a foreign military before 1951. Ancestors who emigrated before 1920 (before Polish independence) are much harder to claim through. No language or residence requirement; processing runs roughly a year or more.

**Germany** offers a constitutional right of restoration for descendants of people whose citizenship was stripped between 1933 and 1945 on racial, political, or religious grounds — most commonly Jewish German families. There's no generational limit, no time limit, no language or residence requirement, and dual citizenship is allowed. A 2021 expansion widened coverage to those who lost or couldn't acquire citizenship through flight, duress, or marriage. Processing typically runs roughly 1.5–3 years.

**Hungary** offers simplified naturalisation with no residence requirement and no generational cap — but there's a real gate: a basic Hungarian-language interview at the consulate. For many diaspora applicants, that language requirement is the deciding factor. Processing runs roughly 6–18 months.

**Italy** underwent a major restriction in 2025. Law 74/2025 — the 'Tajani decree,' upheld by the Constitutional Court in March 2026 — ended unlimited descent. Automatic recognition is now limited to those with an Italian parent or a grandparent born in Italy. The classic great-grandparent claim is largely closed. Cases filed by March 27, 2025 keep the old unlimited rules. Pre-1948 cases involving the female line still require a court petition.

Published processing times reflect how long governments say they take once an application is complete and accepted. Several things sit outside that window.

• Document gathering for descent claims can take months or years before you even file — civil registry records, apostilles, and translations all add time.
• Enhanced due diligence, now mandatory in Dominica since 2024 and standard across CBI programs, can extend timelines if additional documentation is requested.
• Mandatory visits or interviews — Antigua's 5-day visit requirement and Hungary's language interview — must be completed as part of the process.
• Processing backlogs at consulates and national offices vary by country and year; the published estimate is a floor, not a ceiling.
• For descent routes, a broken chain — an ancestor who lost citizenship, or a generation that didn't register in time — can end the claim entirely regardless of how long you've been preparing.

The fastest absolute route is Vanuatu's CBI at roughly 1–2 months — but the EU visa suspension changes the value calculation significantly. For applicants who prioritize Schengen access alongside speed, the Caribbean five deliver citizenship in 4–6 months at donation thresholds starting at $200,000.

For US entrepreneurs specifically, Grenada, Turkey, and Egypt each grant E-2 treaty-investor visa eligibility — a separate benefit that makes those programs attractive beyond passport strength alone.

For anyone with European ancestry, descent routes offer an EU passport at minimal financial cost. Ireland and Poland are the most accessible for Americans with qualifying grandparents. Germany's restoration route is available to a specific population with no generational limit. Hungary's route is open broadly but requires passing a Hungarian-language interview.

Family inclusion matters too. All CBI programs listed here allow family members to be included on the application. The Ireland and Poland descent routes don't automatically extend to family — each family member needs their own qualifying ancestry or chain. Hungary's simplified naturalisation does allow family inclusion.

No tool or article determines whether a specific application will succeed — each government makes that call on every file submitted. What the published rules do is set the bar clearly so you can assess whether your situation likely matches before investing time and money.
