Franco-Iranian \& Franco-Lebanese Dual Nationality: The Hidden Travel Trap in Conflict Zones

France fully allows multiple nationalities. It is possible to hold two or even three nationalities under French law. According to service-public.gouv.fr, this freedom is exercised without restriction on the French side.

But this freedom creates a dangerous illusion when the second nationality country refuses to recognize this dual status. This is precisely the case with Iran — and, to a lesser extent, Lebanon. French nationals who, upon setting foot in their country of origin, become exclusively Iranian or Lebanese in the eyes of local authorities, losing de facto all French consular protection.

This non-recognition is a deliberately used diplomatic weapon. It creates a total blind spot in which no consular protection is possible. For Paris, a Franco-Iranian is fully French; for Tehran, they are only Iranian. The international rule of dominant nationality confirms this legal void: a State cannot grant diplomatic protection to one of its nationals against a State whose nationality that person also holds.

The entire Iranian territory is classified red by France’s Quai d’Orsay — the maximum alert level, rarely used. French nationals, including dual nationals, are formally advised against traveling to Iran for any reason. This classification reflects a documented reality: Iran practices what the Quai d’Orsay itself calls « hostage diplomacy ».

The principle is cynical but effective: Franco-Iranian nationals are arbitrarily arrested on vague charges of espionage or « threats to national security. » They are then used as bargaining chips in diplomatic negotiations with France and Western countries. According to the IFRI (French Institute of International Relations), this strategy has been a deliberate element of Iranian foreign policy for several decades.

Evin Prison: the hidden destination of dual nationals

Evin Prison, in Tehran, has become the symbol of this diplomacy. Since the 1980s, it has housed a disproportionate number of dual nationals and foreigners, many of whom have committed no crime recognized under international standards. In September 2022, during the Mahsa Amini protests, the IRGC (Revolutionary Guards) targeted Evin detainees — Human Rights Watch documented treatment that, by international law definitions, constitutes torture.

After the Israel-Iran conflict of June 2025: increased repression

The context has dramatically deteriorated since June 2025. Following hostilities between Iran and Israel, Iranian authorities have reinforced military presence across the country and intensified the hunt for people suspected of espionage or national security threats. According to the Canadian government, since this conflict, the number of arrests of foreign travelers has increased, and in many cases, Iranian authorities have not notified foreign embassies of these arrests.

New visa restrictions were also introduced in September 2025: nationals from Western Europe, Australia, the United States, and Canada must now visit Iran as part of an approved guided tour. Independent travel is prohibited.

These risks are not theoretical. Here are the most emblematic documented cases:

Cécile Kohler and Jacques Paris (2022–2025)

In November 2025, French teacher Cécile Kohler and her partner Jacques Paris were released from Evin Prison in Tehran, where they had been detained for 1,277 days — between May 2022 and November 2025. According to Wikipedia, even after their release from prison, they remained under house arrest at the French Embassy in Tehran, unable to leave the country. Cécile Kohler was not Franco-Iranian — she was an ordinary French citizen who came as a tourist. This illustrates that the risk concerns not only dual nationals, but any French person.

Fariba Adelkhah

A Franco-Iranian researcher at CERI/Sciences Po, she was arrested in June 2019 and sentenced to six years in prison. Her case revealed to the public that Franco-Iranians — including those engaged in scientific research — are particularly vulnerable. Her Iranian nationality was the key that allowed authorities to block all French consular intervention.

The common trap: passport confiscation

In May 2007, Iranian authorities temporarily confiscated the passport of Franco-Iranian journalist Mehrnoush Solouki, preventing her from leaving the country. Passport confiscation is a documented tool used to force a dual national to remain under Iranian control. According to Human Rights Watch, this mechanism deliberately targets dual nationals who came to visit family, with no visible political or media activity.

Unlike Iran, Lebanon officially recognizes dual nationality and encourages it for its diaspora. But this recognition creates a different trap: being Franco-Lebanese means Lebanese authorities consider you primarily Lebanese on their territory, with all the obligations that entails.

According to the French Ministry of Foreign Affairs, given the volatile security context in Lebanon and the region, French nationals are strongly advised not to travel to Lebanon unless for imperative reasons. The situation remains uncertain and highly volatile, despite the ceasefire with Israel that came into effect on November 27, 2024. Israeli strikes continue regularly, particularly in the South and East of the country.

The Israeli stamp trap

For a Franco-Lebanese person who has visited Israel, returning to Lebanon can become a nightmare. According to the Belgian SPF Foreign Affairs, access to Lebanese territory is refused to holders of a passport, plane ticket, or any document showing a visit to Israel. An unauthorized visit to Israel is criminally punishable in Lebanon. If you are Franco-Lebanese and have visited Israel, request a clean French passport before any trip to Lebanon.

Areas to absolutely avoid

According to the Swiss DFAE, the following areas are formally advised against:

• South Lebanon (south of the Litani River): near-daily Israeli airstrikes despite the ceasefire
• The Bekaa Valley (Baalbek-Hermel): presence of non-state armed groups, regular clashes
• Southern Beirut suburbs (Dahiye): Borj el Barajneh, Haret Hreik — areas not entirely controlled by official forces
• Tripoli and the Akkar governorate: high tensions, armed clashes between factions

A systematically collapsing infrastructure

Beyond security risks, Lebanon presents a vital risk linked to the collapse of its infrastructure. According to Human Rights Watch, power cuts exceed 20 hours per day in several regions. Medically, hospitals require upfront payment and evacuations to Jordan or Cyprus are sometimes necessary in serious emergencies. Never travel to Lebanon without medical repatriation insurance covering evacuations to a third country.

A little-known and lasting side effect of Franco-Iranian dual nationality: it prevents you from traveling to the United States under the ESTA program (Visa Waiver Program). This restriction is permanent and irrevocable.

According to demandevisa.fr, if you currently are or have ever been the holder of an Iranian passport, you cannot benefit from the ESTA visa waiver program to travel to the United States. This rule applies even if you no longer hold the Iranian passport. Having held an Iranian passport at any point in your life is sufficient to ban you from ESTA.

Required alternative: the American B1/B2 visa. Expect 3 to 6 months processing time, $160 in fees, in-person appointments at the US Embassy, and extensive documentation proving the legitimacy of your trip. The United States may request justification for all your travels to Iran and any activity that could present a national security risk.

Faced with all these risks, here are the concrete measures every Franco-Iranian or Franco-Lebanese person must take before any trip.

Universal measures (Iran and Lebanon)

• Register on Ariane from the French Ministry of Foreign Affairs (free): diplomatie.gouv.fr. This registration allows the embassy to be informed of your presence on the territory and can speed up intervention in a crisis.
• Leave copies of documents (passports, birth certificates, local lawyer contacts) with a trusted person in France before leaving. In case of arrest, your family must be able to act immediately.
• Take out travel insurance covering medical repatriation and crisis situations (see the practical info section).
• Memorize emergency numbers: French Embassy in Tehran (+98 21 64706700); Crisis Center of the Quai d’Orsay from France (01 45 31 60 00, 24/7); French Consulate General in Beirut (+961 1 420 000).
• Never store on your phone political conversations, photos of protests, sensitive contacts, or content that could be interpreted as hostile to the regime.

Specific to Iran

• Avoid all gatherings, even peaceful ones.
• Leave Iranian territory as soon as possible if you are already there.
• Know that French bank cards are completely unusable in Iran — bring cash only.
• Do not rely on accounts from travelers who « had a great experience »: arrests are unpredictable and often linked to political inferences unrelated to the reality of your trip.

Specific to Lebanon

• Keep food supplies, medications, and water stocked at home (Consulate General recommendation).
• Never photograph military installations or buildings guarded by security forces.
• If you have visited Israel, request a clean French passport before any trip to Lebanon.
• Check the French Consulate General in Beirut’s alerts daily.
