Fastest Citizenship Through Residency: 21 Investor Routes Ranked by Time to Passport

Most rankings quote the number of years in a country's nationality law. That number is only the start. Three things usually add to it:

• When the clock starts. In Paraguay it starts on the date of the permanent-residence resolution^[1]; in Brazil the Ministry of Justice counts only residence for an indefinite term^[45]; in Portugal the clock starts when the first permit is issued, not when you applied^[13].
• Whether the years count. Almost every country wants real residence. An investor permit with a 7-day or 14-day stay rule keeps your status alive, but it rarely proves the "habitual residence" or "centre of life" that naturalisation needs.
• Processing after you file. Naturalisation decisions take from a few months (Armenia, on its statutory deadlines) to two to five years (Panama, Greece, Portugal); some countries, such as Ecuador, publish no processing time at all.

Our "realistic total" therefore runs from the investment to a passport in hand, for a non-EU main applicant who actually moves. Where our country guide gives a range, we use it unchanged. Where the range is our own estimate, the table says so. For a broader view of how residence differs from buying citizenship outright, see our explainer on citizenship by investment versus a golden visa.

Three countries have a three-year legal minimum that an investor can realistically use: Paraguay, Uruguay (for families) and Armenia. None delivers a passport in exactly three years.

Paraguay: three years of permanent residence, then the Supreme Court

Paraguay's Constitution asks for three years of permanent residence, counted from the date of the permanent-admission resolution^[1]. Before April 2026 most foreigners spent about two years on temporary residence first. The Investor Pass, created by Ministry of Industry and Commerce Resolution 0283/2026, skips that stage for investors putting US$150,000 into tourism or US$200,000 into real estate or Paraguayan securities^[2]. A separate US$70,000 productive-investment route with five local jobs also gives permanent residence. The Supreme Court then wants proof that you live and work or do business in Paraguay, and the court stage adds about one to two years. Our Paraguay naturalisation guide puts the realistic total at about 4.5–6 years.

The catch is renunciation. According to the Chamber of Deputies, current practice includes language and history exams and a renunciation of your nationality of origin; a bill filed on 4 August 2025 to remove both was still in committee in May 2026^[3]. Whether renouncing before a Paraguayan court ends your original citizenship depends on your home country's law. The residence side is covered in our Paraguay Investor Pass residency guide.

Uruguay: three years with family, no investment required

Uruguay's Constitution grants legal citizenship after three years of habitual residence with family in the country, or five years without, plus good conduct and a livelihood^[5]. The Corte Electoral charges nothing, absences may not exceed six consecutive months, and applicants must understand and speak Spanish^[4]. There is no investment threshold. The ~US$2.1 million property figure often quoted for Uruguay is only the condition for the 2026 tax holiday, not for residence or citizenship. Our Uruguay legal citizenship guide estimates 3½–5 years from arrival to passport for families, and explains the remaining passport issues for legal citizens. Uruguay does not ask you to give up your existing nationality.

Armenia: three years, from a new investor permanent residence

Under Article 13 of Armenia's Law on Citizenship, an adult can apply after three years of lawful residence, if they are proficient in Armenian and know the Constitution; Article 13.1 recognises dual citizenship^[33]. The Constitution test has 33 multiple-choice questions, and the statutory review stages add up to roughly 70 working days before the file reaches the President, who decides by decree with no fixed deadline^[35]. From 1 November 2026, amendments to the Law "On Foreigners" add investment in Armenia as a new ground for permanent residence; unlike the revised business ground, which now needs three years of temporary residence in the previous five, the published summary sets no prior-residence condition for it^[34]. The thresholds are left to a government decree that was not yet published when we checked, so the earliest investor naturalisations would come in late 2029. In August 2026 the government said it plans to restrict the separate fast track for ethnic Armenians; the ordinary three-year route was not affected^[36]. Learning Armenian to the required level is the real barrier for most investors. Follow our Armenia investor residence page for the decree.

Argentina's Citizenship Law 346 still lets foreigners naturalise after two years of continuous, legal residence. Under the wording added by DNU 366/2025, "continuous" means not leaving the country at all during those two years^[6][7]. Very few investors can live with a ban on any trip abroad, and we have not verified current court processing times, so we do not rank it. The same decree created Argentina's direct investment route: US$350,000 non-refundable or an US$800,000 bond, presented on 2 October 2026, whose legal basis is still before the Supreme Court. See our Argentina investment citizenship guide for the litigation.

The Dominican Republic is often marketed as fast. Its 1948 Naturalisation Law, Law 1683, as amended by Law 4063 of 1955, allows naturalisation after two years of uninterrupted residence, and after only six months for foreigners who have founded industries or own real estate in the country^[39][47]. The government's service portal now asks for permanent residence and lists a separate investor track with a US$200,000 minimum, with about 12 months' processing^[48]. We could not confirm how the Interior Ministry applies the six-month period to investor residents in practice, so check the Dominican Republic investor residency rules with a local lawyer before relying on them.

Singapore lets permanent residents apply for citizenship after two years, but approval is discretionary, the Global Investor Programme starts at S$10 million, and you must renounce other nationalities^[41]. Fewer than 20 GIP permanent residents were naturalised over 2016–2025, according to our Singapore guide.

Australia and the UK: fast clocks, but not for passive capital

Australia's National Innovation visa is permanent from grant. Citizenship by conferral then needs four years of residence on a valid visa, including 12 months as a permanent resident, with no more than 12 months abroad in those four years and 90 days in the final year, plus a citizenship test^[22]. The route is invitation-only and has no investment minimum in law; see our Australian National Innovation visa guide. The UK Innovator Founder visa can lead to indefinite leave to remain after three years if the business meets growth criteria^[21], and naturalisation follows once you have five years' residence and 12 months with ILR, B1 English and the Life in the UK test^[20]. That is about five years from first grant, as explained on our UK founder visa page. A November 2025 consultation on "earned settlement" could change the baseline, though it proposes keeping three-year settlement for founders.

Mexico and Ecuador: low entry tickets, real residence

Mexico's Nationality Law asks for five years of residence, or two for nationals of Latin American countries and the Iberian Peninsula, with no more than six months abroad in the two years before applying, Spanish and history exams, and a written renunciation of other nationalities^[23]. Time on temporary residence counts. Our Mexico residency guide covers the savings route (about US$73,500 held for 12 months).

Ecuador's investor visa starts at 100 basic salaries, US$48,200 at the 2026 rate, and is a two-year temporary residence; holders can apply for permanent residence after more than 21 months^[38][50][51]. The naturalisation letter then needs three years of regular, continuous residence counted from the permanent visa, with no more than 180 days abroad in each of those years, Spanish and a knowledge test on history, geography and culture, and fees of US$50 plus US$350^[37]. Ecuador does not require you to renounce your nationality of origin^[49]. That puts the total at about five years before the naturalisation decision, whose processing time the official page does not state (our estimate). See our Ecuador investor visa page.

Panama's Constitution allows naturalisation after five consecutive years of residence, with Spanish, a civics exam set by the Electoral Tribunal and a formal renunciation of your current nationality^[8]. Law firms report that files pass through several ministries and that approval rarely comes within a year and often takes two to five^[10]. Investment buys only permanent residence, from US$300,000 in first-sale property since Executive Decree 17 took effect^[9]. Our Panama naturalisation guide therefore puts the total at about 7–10 years; the residency detail is on our Panama Qualified Investor visa page.

Brazil's Migration Law (Law 13.445, article 65) sets four years of residence, the ability to communicate in Portuguese and a clean record. The period falls to one year for applicants with a Brazilian child or spouse and for nationals of Portuguese-speaking countries^[45]. The catch for investors is the start date: the Ministry of Justice counts only residence for an indefinite term, registered with the Federal Police, and allows up to 12 months abroad in total over the four years^[45][30]. Which investor route you choose therefore matters. Investing at least R$500,000 in a Brazilian company under Normative Resolution 13/2017 gives indefinite residence from the start^[44], so a passport in about five to six years is realistic (our estimate). The real estate route under Normative Resolution 36/2018 needs R$1 million (R$700,000 in the North and Northeast)^[46] and first gives a fixed-term authorisation. The 2018 text set two years; Resolution CNIg/MJSP 46/2021 extended it to four, after which it can be converted to indefinite residence^[43][46]. For most non-Lusophone property investors, that means about eight years or more, not four (our estimate)^[32]. See our Brazil investor residency page.

For an EU passport, France is the quickest on paper. French naturalisation needs five years of residence (two in limited cases), B2 French, a civic exam and an interview, and it is discretionary; the administration has up to 18 months to decide^[28]. The investor route is the €300,000 talent card described in our French investor residence guide.

Elsewhere the clocks are longer. Greece needs seven years of lawful residence with Greece as your centre of life and B1 Greek^[12]; Hungary eight years of continuous residence and a constitutional exam in Hungarian^[27]; Cyprus seven of the last ten years plus 12 continuous months, B1 Greek and a civics exam^[25]; Italy ten years and B1 Italian^[24]; Latvia five years to permanent residence plus five more^[26]; Spain ten years^[14]. Portugal, once the benchmark at five years, now requires ten years from first permit issue for most nationalities^[13][42].

Low-stay permits such as the Greece golden visa, Portugal's fund route or Malta's MPRP keep residence status alive with little or no presence, but they do not produce the actual residence that naturalisation requires. The Malta permanent residence programme offers no investor path to citizenship. Our guide to EU citizenship options for investors and the European residence-by-investment comparison cover these programmes in depth.

The United States and Canada sell permanent residence, not citizenship, and both count physical presence. A US green-card holder can naturalise after five years, with 30 of the last 60 months physically in the country, an English test and the civics test^[19]. EB-5 starts at US$800,000 in a targeted employment area, and I-526E processing alone runs from about a year to over four years; see our US naturalisation guide. Canada requires 1,095 days of physical presence in five years, at least 730 of them as a permanent resident, plus a language check and test for ages 18–54^[15]. The only open investor route is Québec's: a C$1 million five-year investment and a C$200,000 contribution^[16]. Our Canadian citizenship guide puts the total at 6–8+ years.

New Zealand's Active Investor Plus visa gives residence from NZ$5 million with only 21 days of presence over three years, but citizenship needs at least 240 days in each of the last five years and 1,350 days in total^[29]. Investors who use the minimum-stay design will not qualify. See our New Zealand investor visa page.

• UAE golden visa holders have no residence route to citizenship. Emirati nationality comes only by nomination, and ordinary naturalisation for non-Arabs needs 30 years; see our UAE nationality guide.
• Swiss lump-sum taxation residents need a C permit and ten years' residence before ordinary naturalisation.
• Japan's Business Manager visa now implies about ten years before naturalisation, and you must give up your current nationality^[17].
• Costa Rica investor residency leads to naturalisation only after seven years' official residence; dual nationality is allowed^[11].
• Spain's golden visa closed on 3 April 2025, and the general naturalisation period is ten years^[14].
• Portugal's investor residence still opens the door to the EU, but now on a 14–17-year realistic timeline to a passport.
• Austria has no fixed residence path for investors; a passport can come only through the discretionary "special interest" route under Section 10(6) of the Citizenship Act, explained in our Austrian discretionary citizenship guide.

If the goal is a second passport rather than a new home, no residence route competes with direct citizenship. Turkey grants citizenship by presidential decision after a US$400,000 property purchase held for three years, with no residence requirement^[40]; practitioners quote four to twelve months. See our Turkish citizenship by property guide. El Salvador's Freedom Visa asks US$1 million in bitcoin or USDT. The Caribbean programmes cost less but face EU visa-waiver pressure; compare them in our ranking of the cheapest second passports and our list of the strongest passports you can obtain by investing. If you plan to hold three nationalities, check the rules first in can you have triple citizenship.

• Families ready to move to South America: Uruguay, with no investment and no renunciation, or Paraguay if you accept the renunciation question and want permanent residence from day one.
• Latin American or Iberian nationals: Mexico (two years) and Spain (two years) are faster than anything else here.
• Founders: the UK Innovator Founder route (about five years) and Australia's National Innovation visa (about four years from grant).
• Investors who want an EU passport: France (five years, discretionary) or Greece (seven years) if you will live there; otherwise accept that no residence route is quick.
• Investors who will not relocate: look at direct citizenship, not residence. The residence programmes in our cheapest residency ranking and the full golden visa directory are for people who want the right to live somewhere, with a passport as a long-term option.
