How to Apply for Portuguese Citizenship by Descent

This page is informational, not legal advice. It describes the Portuguese citizenship application process in general terms. For guidance on your specific situation, consult a licensed Portuguese immigration attorney. Information reflects Portuguese law and IRN procedures as of 2026-04-25.

Two submission routes

Attorney-submitted (IRN digital platform)

Since October 2024, licensed Portuguese attorneys can submit applications directly through the IRN digital platform, bypassing the consulate queue. Processing: 18–42 months. Recommended for grandchild cases and anyone who values speed.

Consulate-submitted (DIY)

You submit your complete document package at a Portuguese consulate, which forwards it to CRC Lisbon. Processing: 2–4 years. No attorney required. May be sufficient for straightforward parent-path cases.

Step-by-step application process

  1. 1

    Gather vital records

    Collect birth, marriage, and death certificates for every link in the chain — from your Portuguese qualifying ancestor down to yourself. For US-issued documents, you will need certified copies (not photocopies), then apostilles from the Secretary of State of the issuing state, then certified Portuguese translations.

  2. 2

    Obtain your grandparent's Portuguese birth record (certidão de nascimento)

    Order from the Civil Registry (Conservatória do Registo Civil) of your grandparent's birth municipality in Portugal, or via the IRN online portal at irn.justica.gov.pt. Portuguese-issued vital records do not need apostilles or translation.

  3. 3

    Pass the CIPLE A2 exam (grandparent path only)

    Register for the next available CIPLE A2 session through the Camões Institute (camonescert.pt). Sessions run in May, July, and November at US locations including Berkeley, Boston, Newark, and Washington DC. Slots fill quickly — monitor ciple-alert.com for registration notifications. Allow 2–6 weeks after the exam for results.

  4. 4

    Gather effective connection evidence (grandparent path only)

    The A2 certificate is the primary evidence of ligação efetiva under Portaria 1403-A/2006. Supplement it with: NIF documentation showing active use, records of visits to Portugal, Portuguese cultural organization membership, or property records in Portugal.

  5. 5

    Order your criminal record certificate — ORDER LAST

    This is the most time-sensitive document. Criminal record certificates expire 3 months from issuance. Order after all other documents are ready. You need: (1) FBI Identity History Summary (fbi.gov/investigate/identify-me) and (2) state criminal history records for every US state you have lived in after age 16. The FBI process takes 3–5 weeks; state processes vary.

  6. 6

    Choose your submission route

    Option A (faster): retain a Portuguese attorney who can submit via the IRN digital platform — 18–42 months processing. Option B (DIY): book an appointment at a Portuguese consulate and submit your package there — 2–4 years processing. With Option B, the consulate reviews for completeness and forwards your package to CRC Lisbon.

  7. 7

    Wait for CRC Lisbon review

    Whether submitted by attorney via the IRN platform or by consulate, the Conservatória dos Registos Centrais (CRC) in Lisbon reviews and decides all citizenship-by-descent applications. CRC may request additional documents during review. Respond promptly — delayed responses extend processing time.

  8. 8

    Receive decision and register citizenship

    If approved, you receive a Portuguese birth registration entry (assentamento de nascimento). You can then apply for a Portuguese passport at any Portuguese consulate or in Portugal. Adult passport fees vary — confirm current rates at the consulate.

Document checklist

All US-issued documents require an apostille and a certified Portuguese translation. Portuguese-issued documents need neither.

All applicants (both paths)

  • Your birth certificate — long-form, apostilled, with certified Portuguese translation
  • Your parent's birth certificate — apostilled, translated if US-issued
  • Your parent's marriage certificate (if applicable) — apostilled, translated if US-issued
  • Your grandparent's certidão de nascimento (Portuguese birth record) — from Civil Registry of birth municipality
  • Your grandparent's death certificate (if deceased) — apostilled, translated if US-issued
  • Your grandparent's marriage certificate — apostilled, translated if US-issued
  • Criminal record certificate — FBI + all states lived in after age 16 — ORDER LAST (3-month validity)

Grandchild path only (additional items)

  • CIPLE A2 certificate — from the Camões Institute after passing the exam
  • Proof of effective connection — A2 is primary; supplement with NIF documentation, Portugal visit records, cultural organization membership, or property records

Name discrepancy warning

Americanized names can freeze applications

Americanized names are a common source of delays. Examples: José appearing as Joseph, António as Anthony, Maria as Mary, Fernanda as Frances. If your ancestor's Portuguese birth record shows a different name than their US vital records, include a sworn affidavit attesting that the names refer to the same person and explaining the discrepancy. Some consulates are stricter than others — having the affidavit ready prevents avoidable delays.

US Portuguese consulates — no jurisdiction restriction

Unlike the Italian consular system, Portugal imposes no jurisdiction restriction. You may submit your application at any of the 6 US Portuguese consulates regardless of your state of residence.

US Portuguese consulates (commonly cited locations):

Boston, New York, Newark, San Francisco, Los Angeles, Washington, D.C.

Verify the current list, contact information, and appointment procedures at irn.justica.gov.pt before booking.

The adjudicating authority

Instituto dos Registos e do Notariado (IRN), Ministry of Justice, Portugal

IRN — the Instituto dos Registos e do Notariado — is the Portuguese government body responsible for all citizenship-by-descent adjudications. Applications submitted through a consulate are forwarded to the Conservatória dos Registos Centrais (CRC) within IRN in Lisbon. Attorney-submitted applications go directly via the IRN digital platform.

Frequently asked questions

How long does the Portuguese citizenship application take?
Processing time depends on the submission route and your generation. For children of a Portuguese parent, expect 9–18 months. For grandchildren using the attorney-submitted IRN digital platform route, expect 18–42 months. For grandchildren submitting through a Portuguese consulate, expect 2–4 years due to CRC Lisbon backlog. Always confirm current wait times with the consulate or a licensed attorney.
Do I need a Portuguese attorney?
A Portuguese attorney is optional but strongly recommended if you want to use the faster IRN digital platform route. The digital platform (launched October 2024) is accessible only to licensed attorneys — it bypasses the consulate queue and routes directly to the CRC Lisbon digital processing team, reducing processing time from 2–4 years to 18–42 months. For straightforward parent-path cases, the consulate route is DIY-able. For grandchild cases requiring A2 and effective connection evidence, professional guidance is often worth the investment.
My criminal record certificate expired — what do I do?
Order a new one. Criminal record certificates are only valid for 3 months from issuance — submitting an expired certificate will result in your application being returned or delayed. This is why we recommend ordering the criminal record last, after all other documents are gathered and apostilled. FBI criminal history background checks are ordered at fbi.gov/investigate/identify-me; state records depend on each state's process.
