Argentine Citizenship by Descent

Summary

Children born abroad to at least one Argentine parent can opt for Argentine citizenship under Article 1, clause 2 of Ley 346. The statute treats descent as a right of election rather than automatic transmission — you file a formal option with an Argentine consulate if you're abroad, or through the Argentine civil-registry process if you're already in Argentina. Once approved, you're treated as an Argentine by option (por opción), which is functionally equivalent to Argentine-by-birth for passport, voting, and dual-citizenship purposes.

Grandchildren and more distant descendants are not directly covered just because an ancestor was Argentine. The usual path is sequential: the eligible parent claims Argentine nationality first, and then the child applies as the child of an Argentine. Argentina permits dual citizenship without restriction, and registering as Argentine by descent does not require renouncing your current nationality.

Eligibility

You qualify to opt for Argentine citizenship by descent if:

• You were born outside Argentina.
• At least one of your parents is Argentine, or can first become Argentine by option through their own Argentine parent.
• You can document the parent-child chain with official civil records.
• You have not previously renounced Argentine citizenship.

If your Argentine ancestor is a grandparent

Grandchildren of Argentines do not have a direct claim if the parent in between never became Argentine. Two common workarounds:

• Chain registration: your parent, as the child of the Argentine grandparent, registers first by option; then you register as the child of an Argentine. This usually only works if your parent is able and willing to complete their own registration.
• Residency and naturalization: move to Argentina, take up legal residency, and naturalize after two continuous years.

If your Argentine parent was already registered

If your Argentine parent already has a DNI or Argentine passport, the path is more straightforward — the consulate treats your application as a parent-to-child registration. If the parent never claimed Argentine documents, they will typically need to complete their own paperwork first.

What This Route Allows

This route can help confirm or document citizenship in Argentina when the citizenship-creating facts named above are proven. For many people in this category, the main work is evidence: civil records, family-link records, prior citizenship records, and any registration or restoration paperwork needed to show the claim.

What This Route Is Not

This is not a shortcut around documentation. Even when the citizenship claim is based on a right, you still need records that prove each required fact and family link.

This is also not an unlimited remote-ancestor route. If your closest Argentine connection is a grandparent, great-grandparent, or older ancestor, the parent between you and that ancestor usually needs to be an Argentine citizen already or able to claim Argentine nationality first.

Next Steps

1. Identify the Argentine parent link. If your parent is already an Argentine citizen, start with their Argentine birth record, DNI, or passport. If the connection is through a grandparent or older ancestor, confirm whether your parent can claim Argentine nationality first.
2. Gather civil records for the Argentine chain. You'll need the Argentine parent's or grandparent's Argentine birth certificate, plus every birth or marriage certificate needed to connect the line to you.
3. Apostille all foreign documents. U.S. birth, marriage, and divorce certificates need a state-level apostille from the Secretary of State of the issuing state.
4. Translate documents into Spanish if required by the consulate or Argentine authority handling the case.
5. Book an appointment with your nearest Argentine consulate. The consulate reviews the filing and handles the birth-registration process.
6. Obtain your Argentine birth record. Once the option is accepted, your birth is inscribed in the Argentine Registro Civil and you receive a partida de nacimiento argentina.
7. Apply for a DNI and passport after the birth registration is complete.
