Complete guide to claiming Iranian citizenship through your ancestors — eligibility, documents, timeline, costs, and how to file. Reviewed by Ancestra's middle east counsel.
Quick Facts
Eligibility
Iran citizenship by descent is governed by Tabeiyat by descent (paternal). Iranian citizenship passes through the father by default; maternal-line transmission is restricted. We file through the Iranian Ministry of Foreign Affairs and consulates, recovering Pahlavi and Qajar-era records.
Eligibility for Iran citizenship by descent depends on three key factors: (1) the generational distance between you and your Iranian ancestor — most Iranian programs cover up to parent (2nd generation), but some go further; (2) whether the citizenship line was broken by naturalization in another country before the next child's birth in the line; and (3) the specific statute in effect at the time of each birth in the line.
Ancestra's written eligibility opinion addresses all three factors for your specific case, citing the exact statute and consular venue that applies. Our genealogists specialize in recovering the civil registry, parish, and consular records required to establish the unbroken lineage that Iranian nationality law requires.
Key constraints & rules
The #1 thing to know
Iran's non-recognition of dual citizenship means dual citizens (including US-Iranian duals) face significant risks when traveling to Iran, including potential detention.
Generational limit
1 generation (father only for most cases). Iranian mothers married to foreign men can apply for citizenship for children (2006 reform), but process is complex and not automatic.
Transmission rule
Primarily paternal. 2006 reform allows maternal-line applications but with complex conditions.
Dual citizenship
Not recognized — Iran does not recognize dual citizenship. Dual citizens are treated solely as Iranian while in Iran.
Language requirement
None for descent path.
Residency requirement
None for paternal descent.
Filing authority
Ministry of Foreign Affairs (for abroad) or Ministry of Interior (for in-country).
Key statute
Iranian Civil Code, Article 976; Nationality Law of 1929 (as amended 2006)
The 5-step process

Genealogy & document recovery — Our network of genealogists retrieves the Iranian records from the relevant civil registry and parish archives, plus the destination-country naturalization (or no-record) documentation.

Iran FAQ
How do I qualify for Iran citizenship by descent?
You qualify for Iran citizenship by descent if you have a Iranian ancestor (typically up to parent (2nd generation)) and the citizenship line was never broken by naturalization in another country before the next child's birth. Iranian citizenship passes through the father by default; maternal-line transmission is restricted.
How long does the Iran citizenship by descent process take?
The Iran citizenship by descent process typically takes 12–24 months, depending on the filing venue (consular, judicial, or administrative) and the completeness of your dossier. Ancestra quotes a specific timeline forecast in your eligibility memo based on the consulate or court that will handle your case.
What documents do I need for Iran citizenship by descent?
You'll need: certified long-form birth certificates for each person in the line, marriage certificates (and divorce/death where applicable), the Iranian ancestor's birth certificate (retrieved from the civil registry or parish of their commune of origin), naturalization records (or a "no record" letter), apostilles on all foreign documents, and certified sworn translations. Ancestra retrieves most of these documents on your behalf.
How much does Iran citizenship by descent cost?
Iran citizenship by descent costs $3,000 – $12,000 (all-in, fixed fee), all-in on a fixed fee basis. This typically includes document retrieval, apostilles, translations, dossier compilation, consular filing, and counsel representation through the oath. Ancestra quotes a specific fixed fee in writing after consultation — no hourly billing, no add-ons.
Can I keep my current citizenship if I claim Iranian citizenship?
Iran permitted dual citizenship. You can hold both your current citizenship and your Irann citizenship simultaneously — no renunciation required.

Usually not. Most Iran citizenship by descent filings are handled at the Iranian consulate in your country of residence. In-person attendance at the oath ceremony may be required, but counsel can often attend by proxy.
