How to Build a Citizenship Strategy for Your Children Before They Turn 18

A child’s citizenship can be shaped by birth location, family lineage, residence, language, and investment, but many of these levers become unavailable or far more costly once the child turns 18. Planning early allows parents to assemble a portfolio of passports that can improve education, work, and mobility options.

Birthplace and Unconditional Jus Soli

• Only about 33 countries still grant unconditional birthright citizenship (jus soli).
• Nearly all of them are in the Americas – e.g., Canada, the United States, Brazil, Argentina, and most Caribbean states.
• The United Kingdom ended unconditional jus soli in 1983, Australia in 1986, and Ireland by referendum in the mid‑2000s, leaving the Western Hemisphere as the primary source of birthright citizenship.
• On 30 June 2026, the U.S. Supreme Court struck down an executive order that would have ended birthright citizenship for children of temporary or unlawful residents, reaffirming that anyone born on U.S. soil is a citizen under the Fourteenth Amendment.
• Brazil adds a residency benefit: a child born there is Brazilian at birth, and the parents may apply for permanent residency immediately and naturalize after one year.

Inheriting Existing Citizenship

• Most countries automatically transmit nationality from parent to child, so a child of a dual‑national parent can start life with two passports without any application.
• If a parent has an unclaimed citizenship (e.g., through grandparents), formalizing it before the child’s birth can allow the child to inherit it directly.
• For citizenship by descent, the child’s birth must be registered with the relevant consulate or civil registry; failure to do so can create complications later.

Ancestral Claims Are Shrinking

• Several EU and Single‑Market countries extend citizenship to grandchildren, and a few to great‑grandchildren.
• Italy capped jus sanguinis with Law 74/2025; the Constitutional Court upheld the cap in March 2026, ending unlimited generational transmission.
• The Italian Court of Cassation considered on 14 April 2026 whether a naturalized ancestor who did so while their child was a minor severed the bloodline for subsequent generations—a ruling that will affect thousands of claims.
• Canada’s Bill C‑3 (effective December 2025) removed the first‑generation limit but introduced a 1,095‑day (three‑year) physical‑presence requirement for a Canadian parent born abroad before a child born after 15 December 2025.
• In June 2026, Canada temporarily ordered some recent citizenship‑by‑descent recipients to surrender certificates based on unofficial genealogy records, then reversed the decision, raising the evidentiary standard for future claims.

Residence Before Age 18

• Physical residence builds ties that cannot be purchased later.
• Portugal’s revised nationality law (effective 19 May 2026) grants citizenship at birth to a child of foreign parents only if at least one parent has completed five years of legal residence, up from one year previously.
• The same law doubled the naturalization residency requirement to ten years for most applicants (seven years for EU and Portuguese‑speaking nationals) and counts the clock from the issuance of a residence permit.
• Early establishment of a residence permit therefore maximizes the child’s ability to accrue the required presence time.

Education as a Residency Anchor

• School attendance provides demonstrable community ties that many immigration systems now require.
• Portugal’s new great‑grandchild descent route links eligibility to five years of legal residence and a genuine connection to the community—connections often built through schooling.

Language Advantage

• Children acquire native‑level proficiency when raised speaking a country’s language, making language‑test requirements trivial for them.
• Portugal’s naturalization process mandates an A2 Portuguese exam and a civics test; its descent routes for grandchildren and great‑grandchildren also hinge on language proficiency and community connection.

Investment‑Based Citizenship

• Citizenship‑by‑Investment (CBI) and Residence‑by‑Investment (RBI) programs allow families to include dependent children at a lower marginal cost.
• Grenada’s CBI program (under the 2013 Citizenship by Investment Act) requires a non‑refundable $235,000 donation to the National Transformation Fund for a family of up to four, plus roughly $25,000 per additional child, with no residency requirement.
• European golden‑visa schemes similarly permit a main applicant to add a spouse and children to a single application, enabling the children to reside in the host country while the parents work toward citizenship.

Obligations That Accompany Passports

• Dual citizenship can impose obligations such as military conscription—about 60 countries still have compulsory service, and a dual‑national child may be liable in both countries.
• U.S. citizenship entails lifelong tax‑filing obligations regardless of residence, unless the individual renounces the citizenship.
• Some countries require a single nationality election at the age of majority, potentially forcing a child to choose between passports.
• Dual nationality may affect custody arrangements in cross‑border separations, making it important to document how each citizenship was acquired.

Sequencing the Levers

1. Audit existing citizenships – list all passports held by each parent and identify latent ancestral claims through grandparents.
2. Secure birthright or early residence – if the family is mobile, consider a birth in a jus soli country or begin the residence clock early to lock in options.
3. Claim ancestral citizenships promptly – descent rules are tightening; a claim that is straightforward today may become unavailable later.
4. Build residence, schooling, and language ties – these create the “genuine connection” many naturalization and descent pathways now require.
5. Use investment routes to fill gaps – CBI or RBI programs can add a geography not covered by bloodlines and deliver a passport more quickly.
6. Assess obligations – evaluate potential conscription, tax, and nationality‑election requirements before finalizing any acquisition.

By addressing these steps before a child turns 18, families can transform citizenship from a passive accident of birth into a strategic asset that supports education, employment, and long‑term mobility.
