The cheapest second passport in 2026 is usually free — and most advisers never check

The question is usually asked as a shopping question — which passport costs least. Answered that way, the honest number in 2026 is USD 90,000, for Nauru, a programme about eighteen months old whose holders now need a visa for the United Kingdom.

But that is the wrong question, and asking it costs people a great deal of money. We track 21 citizenship-by-descent routes and 34 naturalisation routes alongside the 25 investment programmes. Several of the descent routes cost nothing beyond filing and translation fees, carry no residence requirement, no language test and no renunciation — and deliver an EU passport rather than a Caribbean one.

The cheapest second passport, for a large minority of people asking, is one they already qualify for. Most advisers never ask about the family tree, because there is no commission in the answer.

Start with the four grandparents

Before pricing anything, work backwards through the family. These are the ancestry routes we hold that reach beyond a parent.

Ireland — the Foreign Births Register reaches a grandparent born on the island. No residence, no language test, and Ireland permits dual citizenship. The passport is an EU one with strong access. This is the single most under-claimed route we see.

Italy — jure sanguinis has historically reached back indefinitely through an unbroken line, though the rules tightened sharply in 2025 and the position now turns on generation and dates. Worth checking, worth checking properly.

Poland — confirmation of citizenship is declaratory: it confirms citizenship was never lost rather than granting a new status, so there is no policy risk, no language test and no residence requirement. The catch is the 1920 Act's male-line rule, which rules out a large share of claims through a grandmother for children born before 19 January 1951. Read the rule before you hire anyone.

Lithuania — restoration reaches a great-grandchild of someone who held citizenship before 15 June 1940. No language exam, no constitution test, no residence requirement, and it is a statutory right rather than a discretionary grant. For the Litvak diaspora this is the strongest ancestry route in the Baltics.

Hungary — simplified naturalisation covers descendants of citizens of the pre-1920 Kingdom of Hungary. No residence requirement, no investment. The binding hurdle is conversational Hungarian at the consular interview. Because the pre-1920 borders were much wider, this reaches families in Slovakia, Transylvania, Vojvodina, Transcarpathia and Croatia, plus a large share of the Ashkenazi diaspora.

Slovakia — reaches a great-grandparent, one generation deeper than the Czech limit, with no language test on this route.

Croatia — since the 2020 amendments there is no generational limit at all for emigrants and their descendants, and no language test. Arguably the most generous ancestry route in the European Union.

Bulgaria — origin-based naturalisation reaches a great-grandparent and waives the residence period, the language test and the renunciation requirement. Evidence must now be state-issued documents naming the ascendant, following a 2018 scandal over forged certificates.

Czechia — declaration for children and grandchildren of a Czech or Czechoslovak citizen. Fast, no language test, no residence requirement. One trap: the declaration expressly bars anyone who is a Slovak citizen on the date of declaration, so if you might qualify for both, sequence matters — take the Czech one first.

Also live: Romania, Portugal, Slovenia, Israel and India's OCI — the last of which, despite the name, is not citizenship at all.

What ancestry actually costs

Filing fees, certified translations, apostilles, and archival research. On a straightforward Irish file that is low hundreds of euros. On an Italian or Croatian file requiring records across former Yugoslav, Austro-Hungarian or Italian archives it can run into thousands, and the archives are inconsistent and sometimes destroyed.

Call it USD 500 to USD 8,000 depending on how buried the paperwork is. Against USD 200,000 for a Caribbean contribution, the arithmetic is not close — and the passport at the end is materially stronger.

The cost that actually bites is time. Romania's approval rate collapsed from 88% in 2018 to 0.37% in 2023, with none recorded in 2024 against 50,350 applications. Ireland's Foreign Births Register has run long queues. Ancestry is cheap in money and expensive in patience.

If there is no ancestor: earn it

The second-cheapest route is residence followed by naturalisation, and two jurisdictions make it genuinely fast.

Argentina — two years of residence. That is the shortest naturalisation period of any significant country we track, and the passport is strong.

Paraguay — permanent residence is immediate, and citizenship comes three years from permanent residency, subject to a real arraigo test. Entry to the investor route is USD 70,000, and there are cheaper non-investor bases.

Uruguay — three years with family established in the country, five without, though the practical wait to full civic rights runs longer.

Peru — two years. Brazil — four.

Each of these requires you to actually live there, which is the honest trade. But for someone willing to move, two to four years and a few thousand dollars in fees beats USD 200,000 and a passport that keeps losing destinations.

The comparison nobody puts side by side

The only column where investment wins outright is speed. If you need a travel document in months rather than years and your current passport is genuinely constraining, that is a real reason and the price is what it is. Our full analysis of the investment programmes covers what each one has lost since 2023 — and every open one has lost something.

Three mistakes that cost the most

Buying before checking the family. We have seen files where a Caribbean contribution was paid by someone with an Irish grandparent. The passport they bought is weaker than the one they could have registered for a few hundred euros.

Getting the order wrong. The Czech declaration bars existing Slovak citizens. Taking the Slovak passport first forecloses the Czech route permanently. Similar sequencing traps exist elsewhere, and they are irreversible.

Assuming dual citizenship is allowed. It very often is not. Kazakhstan's new Constitution banned it from 1 July 2026. Azerbaijan, Uzbekistan, Kuwait, Oman, Bahrain, Qatar, Singapore, Japan, China, India and Namibia all prohibit or heavily restrict it. Acquiring a second citizenship can automatically cost you the first — check what your country does before you apply anywhere.

A passport is not a tax plan

Worth stating plainly, because a lot of money is spent on this confusion. Citizenship and tax residence are unrelated in every country on this page except the United States and Eritrea. A second passport does not reduce your tax, and it does not end an existing tax residence.

If the objective is tax, the instrument is a residence plus a regime, not a citizenship. Our tax profiles cover 209 jurisdictions, and the non-dom and flat-tax regimes are usually the thing people actually wanted.

How to find out which route is yours

Start with the four grandparents and their birthplaces, then the eight great-grandparents where you know them. Note any pre-1940 emigration, and any borders that moved — the pre-1920 Hungarian, Austro-Hungarian and interwar Polish frontiers create claims in countries the family never lived in under their current names.

If a residence permit would do instead of a passport, see the golden visa map for 2026.

Browse the routes by country in programmes, or compare them in compare.

Then send us the family tree. We will tell you what you already qualify for, in what order to claim it, and whether buying anything is necessary at all. That answer is frequently no, and we take no commission from any programme, so it costs us nothing to say so.

Every route here is current to our review in August 2026. Ancestry law moves — Italy tightened in 2025, Romania's approvals collapsed, Poland has a bill pending — and each programme page carries its own verification date.
