01Who qualifies

Who qualifies, generation by generation

LIKELY

Can you claim Argentine citizenship through a parent?

Option (Art. 1(2))

A child of a native-born Argentine can opt for Argentine citizenship at the consulate, at any age.

POSSIBLE

Can you claim Argentine citizenship through a grandparent?

Option, generation by generation

Only children of native-born Argentines may opt, but a parent who opts becomes an Argentine by option, not native-born, so the chain generally stops there. It depends on where your parent was born.

What would settle itWhether your parent was born in Argentina. If so, you can opt; if your parent was born abroad to an Argentine, the option is theirs, not yours.

POSSIBLE

Can you claim Argentine citizenship through a great-grandparent?

Option, generation by generation

Only children of native-born Argentines may opt, but a parent who opts becomes an Argentine by option, not native-born, so the chain generally stops there. It depends on where your parent was born.

What would settle itWhether your parent was born in Argentina. If so, you can opt; if your parent was born abroad to an Argentine, the option is theirs, not yours.

02Dates that matter

The dates that matter

No date named in Argentina’s rule decides who qualifies. The answers above turn on the family’s facts, not on when anyone was born or left.

03Mothers’ lines

How mothers’ lines were treated

Argentina’s rule gives the same answer whether the line runs through a mother or a father.

04Keeping your citizenship

Dual citizenship with your home country

You keep your citizenship.

On every open route, the rule lets a citizen of the United States, Canada, the United Kingdom, Australia, New Zealand, Brazil, Argentina or South Africa keep that citizenship.

05The routes

Every route, and the law behind it

Option (Art. 1(2))

Open through a parent

  • LIKELY
    Through a parent

The law

Option, generation by generation

Open through a grandparent or a great-grandparent

  • POSSIBLE
    Through a grandparent

The law

What would settle an unsure case

  • Whether your parent was born in Argentina. If so, you can opt; if your parent was born abroad to an Argentine, the option is theirs, not yours.

06The documents

The documents, as the rule lists them

Option (Art. 1(2))

Through a parent

  • Your parent’s Argentine birth certificate
  • Your birth certificate, apostilled and translated
  • Your parents’ marriage certificate

Option, generation by generation

Through a grandparent or great-grandparent

  • Your ancestor’s Argentine birth certificate
  • Birth records for each generation

Most countries also want proof that no one in the line became a citizen elsewhere before the next birth: the naturalization record with its date, or a letter that none exists.

07What it takes

What it takes: time, cost, the hard part, who decides

Option (Art. 1(2))

Time
A few weeks to a few months: a consulate appointment for a minor, or a federal judge’s proceeding for an adult exercising the option.
Cost
About $200–400: certified and apostilled U.S. records, translations, and consulate fees.
The hard part
Proving your parent was born in Argentina, not just Argentine by descent. If your parent was born abroad, the option is theirs to have exercised, not yours.
Who decides
The Argentine consulate for your address (minors), or a federal judge in Argentina after proving parentage (adults).
The first record
Your parent’s Argentine birth certificate (partida de nacimiento), from The Registro Civil of the province where they were born. Contact the provincial Registro Civil with your parent’s name, birthdate and city; most answer by email or an online request in a few weeks. argentina.gob.ar

How it’s filed

Where
The Argentine consulate general for the applicant's residence, in person: Atlanta (AL, GA, KY, MS, SC, TN), Chicago (IL, IN, IA, KS, MI, MN, MO, NE, ND, OH, SD, WI), Houston (AR, CO, LA, NM, OK, TX), Los Angeles (AK, AZ, CA, HI, ID, MT, NV, OR, UT, WA, WY), Miami (FL, PR, USVI), New York (CT, MA, ME, NH, NJ, NY, RI, VT), or the Embassy consular section in Washington (DC, DE, MD, NC, PA, VA, WV). office list
How
In person; you appear in person
Appointments
Per consulate: email request (New York ryf@mrecic.gov.ar; Washington poderesynacionalidad@embassyofargentina.us; Miami opciones_cmiam@cancilleria.gov.ar) or a web intake form (Los Angeles) that returns a code and instructions. Appointments are free. Email requests are answered by staff, so the agent drafts and sends the request and waits; some posts quote two to three months from opening the file (unverified for U.S. posts). One turno per family member. The appointment itself takes 2–4 hours.
Fee
About $135
Decision
1–8 months
What goes in the file (8)
  1. The applicant's birth certificate, long form listing both parents, with a Hague apostille from the issuing state (Los Angeles wants it issued within the last 6 months)
  2. Spanish translation of that certificate and its apostille
  3. The applicant's valid passport or other photo ID (mandatory for adults)
  4. The native Argentine parent's birth certificate (partida), digital or a certified copy of the full acta from the Registro Civil
  5. The Argentine parent's DNI (not mandatory for adults at most posts)
  6. The other parent's ID or passport (copy)
  7. Proof of the applicant's address in the consulate's jurisdiction
  8. Fees: USD 40 birth registration (per 25 lines), USD 80 option act (up to USD 120 for a long act), USD 15 first DNI; debit card or money order
What goes wrong (8)
  • Any age, and the Argentine parent may be deceased. The option is personal: an adult attends alone; a minor comes with both parents (or a notarized authorization from the absent one).
  • The parent must be native (born in Argentina). A parent who is Argentine by option cannot transmit under Art. 1(2) according to the Cancillería's consular pages; see the generation-by-generation path.
  • The option is complete at the appointment; the DNI follows (Los Angeles: about 6 weeks; New York: 3–6 months). New York warns the Argentine birth entry itself can take up to 5 years to come back.
  • Names must match exactly between the parent's partida, the applicant's birth certificate and the parent's ID.
  • Takes said adults go before a federal judge; the Cancillería's own pages (checked 2026-09-25) show adults opting at the consulate. A federal-court proceeding applies to naturalization (carta de ciudadanía), not to the option. The June 2026 ruling annulling DNU 366/2025 concerned naturalization, not the option.
  • From AR: residents in Argentina opt at a Registro Civil or RENAPER documentation centre, booked through Mi Argentina; the fee is ARS 10,000 and translations must be by a traductor público.
  • From BR, GB, CA, AU, NZ, ZA: the same procedure at the Argentine consulate or embassy for your residence; fees are in local currency or USD by post (unverified per post). A Brazilian birth certificate needs a Spanish translation as well as the apostille.
  • Postal addresses for New York and Washington were found via WebSearch (cnyor.cancilleria.gob.ar and Wikipedia/embassypages.com), not fetched directly; confidence: secondary, verified 2026-09-25. Atlanta, Chicago, Houston, Los Angeles and Miami remain unaddressed. The Resolución RNP 1636/12 option-act template (Anexos I-III) exists at https://www.electoral.gob.ar/nuevo_legislacion/pdf/res1636-12_renaper.pdf but its field-by-field content was not extracted (confidence: snippet).

Option, generation by generation

Time
A few weeks to months for your parent’s option at the consulate; there is no direct route for you afterward.
Cost
About $200–400 if your parent exercises the option first; there is no separate path for you afterward.
The hard part
The option belongs to children of native-born Argentines. Once your parent takes it, they become Argentine by option, not native-born, so the chain stops there for your own children.
Who decides
The Argentine consulate for your parent’s address, or a federal judge in Argentina.
The first record
Your ancestor’s Argentine birth certificate, from The Registro Civil of the province where they were born. Contact the provincial Registro Civil with the name and approximate birthdate. argentina.gob.ar

How it’s filed

Where
The Argentine consulate for each person's residence (see the Option path), one after the other. office list
How

Fee
About $270
Decision
4–18 months
What goes in the file (3)
  1. Step 1, the parent (child of the Argentina-born ancestor): the full option file at the consulate (apostilled and translated birth certificate, the ancestor's partida, ID, fees)
  2. Step 2, the applicant: the same file, with the parent's Argentine option act and new DNI in place of a native parent's partida
  3. The Argentina-born ancestor's partida, so the chain is visible
What goes wrong (3)
  • The same consular option applies to each generation in turn: the parent opts first, then the applicant files.
  • Conflict to resolve before filing: Law 346 Art. 1(2) and the Cancillería's consular pages limit the option to children of native Argentines, but RENAPER's own service page (argentina.gob.ar, checked 2026-09-25) describes the option DNI as for 'hijos de argentinos nativos o por opción'. Ask the consulate in writing whether it will take an option from the child of an Argentine by option before the parent spends money; if it will not, the family's Argentine route ends with the parent.
  • Fee is two sets of consular fees (about USD 135 each).

08Where the records live

Where each record lives, and how to ask for it

  • birth1886–2026

    Registro Civil de la Ciudad Autónoma de Buenos Aires (Dirección General de Registro del Estado Civil y Capacidad de las Personas), for births in the city of Buenos Aires

    Births in the city of Buenos Aires (the Capital Federal). The request needs the full name and an approximate date of birth; a search fee applies if the acta number is unknown.

    Ask
    Online, in Spanish · request page ↗
    Takes
    1–4 weeks
    Good to know (5)
    • Ordered online with a free miBA account and a credit card (the payer need not be the record holder); the digital partida arrives by email with a certificate of authenticity and is identical in value to paper.
    • Consulates want the parent's partida in digital form issued by the Registro Civil (Los Angeles, Miami, Washington), or the original certified copy of the full acta (New York: 'no se aceptan certificados'). Order the full acta.
    • No apostille is needed for an Argentine partida presented at an Argentine consulate.
    • unverified: the current fee in pesos (the city's own page quoted older amounts); urgent service costs extra.
    • Civil registration in the city began in 1886; earlier births are only in Catholic parish registers (FamilySearch has images). A native parent born before civil registration is rare for a living applicant.

  • birth1889–2026

    Registro Provincial de las Personas de la Provincia de Buenos Aires, for births in Buenos Aires province (La Plata, Mar del Plata, the Greater Buenos Aires partidos)

    Births anywhere in Buenos Aires province outside the city. Needs the name, date and the partido or town of birth.

    Ask
    Online, in Spanish · request page ↗
    Takes
    1–6 weeks
    Good to know (3)
    • Digital partidas are requested online and paid by card; the system shows fee and delivery time by urgency before payment (unverified amounts).
    • The platform needs a user account with Argentine identity data; a relative or representative in Argentina can order if the account cannot be opened from abroad (unverified whether a foreign applicant can register).
    • Older books (roughly before the 1970s) may need a search; allow the long end of the range.

    Checked 25 September 2026 · source ↗

  • birth

    The Registro Civil of the other province where the parent was born (Córdoba, Santa Fe, Mendoza, Tucumán and the rest each run their own)

    Each province runs its own civil registry and its own online partida service; find it from the province's government site. There is no national partida service.

    Ask
    Online, in Spanish · request page ↗
    Takes
    1–13 weeks
    Good to know (3)
    • unverified: per-province portals, fees and whether they deliver digital partidas abroad were not checked in this pass.
    • Provincial civil registration began at different dates in the 1880s–1890s; before that, parish registers.
    • Ask for the digital full acta, because consulates want one issued by the civil registry in digital form or as a certified copy of the full entry.

    Ask
    Online, in Spanish · request page ↗
    Takes
    1–6 weeks
    Good to know (1)
    • Not required by the consulates' published checklists; useful only where a name changed between the parent's partida and the applicant's birth certificate (names must match exactly, New York warns).

    Checked 25 September 2026 · source ↗

  • citizenship

    RENAPER (Registro Nacional de las Personas): the parent's DNI record, which shows Argentine nationality

    A living parent's current or expired Argentine DNI is enough for most consulates as proof of identity; for adults the parent's DNI is not mandatory (Cancillería).

    Ask
    In person, in Spanish · request page ↗
    Takes
    1–9 weeks
    Good to know (1)
    • A parent who never renewed an old Libreta de Enrolamiento or Libreta Cívica can still transmit; the partida is the proof that matters. Argentines do not lose nationality by naturalizing abroad, so no no-naturalization proof is needed.

Translations

Spanish
Who may translate
Any certified translator
About
$0–$60 a page

The applicant's apostilled foreign birth certificate must be translated into Spanish. Standards differ by post: New York and Miami accept a simple (unofficial) translation; the Washington embassy wants a notarized or translation-agency certified one; Los Angeles asks for a professional translation. In Argentina itself (RENAPER), a translation by a traductor público is required. The translation itself is not apostilled.
