Losing French nationality by becoming Paraguayan: true or false 2026

This is the question that comes up at every expat happy hour in Asunción: "If I become Paraguayan, do I lose my French nationality?" The answer is simple, definitive, and reassuring: no. France recognizes dual nationality, as does Paraguay. You can be French and Paraguayan, with two passports, two nationalities, and the rights associated with each. But this simple answer deserves a comprehensive guide, because myths persist, legal nuances exist, and Paraguayan naturalization is worth explaining in detail.

This guide covers Paraguayan nationality, its conditions and procedure, Franco-Paraguayan dual nationality, what the laws of both countries say about it, the concrete advantages of having two passports, and the very rare cases where a French national can indeed lose their nationality. Living in Paraguay and becoming Paraguayan is not one of them. The residency procedures in Paraguay constitute the first step in this journey.

The myth: "I will lose my French nationality"

Where does this belief come from?

Several factors fuel it:

• Confusion with other countries: some states do not allow dual nationality and require renunciation: Japan, which requires choosing before age 22; China, where nationality is automatically lost; Singapore, and a few others. France is not on this list, nor is Paraguay.
• Former French legislation: historically, the Nationality Code stipulated automatic loss in the event of voluntary acquisition of a foreign nationality. This rule was repealed in 1973, by the law of January 9, 1973. The myth survives among those who remember the old rule, obsolete for over fifty years.
• Confusion between loss and forfeiture: forfeiture, the forced withdrawal by the state, exists in French law, but it is reserved for extreme cases, terrorism, treason, and in no way concerns expatriates who acquire another nationality.
• Rumors among expatriates: in expat communities, information spreads by word of mouth, and errors travel faster than truths. "My neighbor lost his nationality when he became Paraguayan": false, either he renounced voluntarily, or he is confusing it with another country. Always check with reliable sources, such as a consulate, the Civil Code, or a specialized lawyer, never with a neighbor.

What French law says

The Civil Code is perfectly clear:

• Article 23: any person who acquires French nationality may combine it with another nationality. France explicitly recognizes dual and multiple nationality, without limitation.
• Article 23-1: the acquisition of a foreign nationality does not entail the loss of French nationality. This is the key provision: becoming Paraguayan, American, or Brazilian does not take anything away from you, unless you voluntarily renounce it.
• No limit on the number of nationalities: you can be French, Paraguayan, and American simultaneously. Each nationality follows its own rules, but France never asks you to choose.

What Paraguayan law says

• Article 149 of the 1992 Constitution: multiple nationality may be admitted by international treaty or reciprocity between the states of origin and adoption. As France recognizes dual nationality, the condition of reciprocity is met: a French national can become Paraguayan without losing anything.
• In practice: Paraguay has never asked a naturalized French national to renounce their original nationality. French nationals who have become Paraguayan retain both nationalities without any difficulty.

How to obtain Paraguayan nationality

Means of acquisition

Means	Conditions	Timeline
Ordinary naturalization	Continuous residence in Paraguay for a minimum of 3 years, good conduct, exercise of a profession or activity, sufficient knowledge of Spanish, clean criminal record.	3 years of residence, then 6 to 18 months of judicial procedure
Naturalization by marriage	Marriage to a Paraguayan citizen and residence in Paraguay for a minimum of 3 years of marriage, with the same conditions of conduct, activity, and criminal record.	3 years of marriage, then 6 to 18 months of procedure
Birth in Paraguay (jus soli)	Any person born on Paraguayan territory is a Paraguayan national by birth, Article 146 of the Constitution. No procedure: nationality is automatic.	Automatic at birth
Descent (jus sanguinis)	Child born abroad to a Paraguayan parent, subject to registration with the Paraguayan consulate in the country of birth.	Automatic, subject to registration

Ordinary naturalization: the detailed procedure

For a French national established in Paraguay for 3 years or more, this is the most common route:

1. Verify the conditions:
   • 3 years of residence: continuous, under renewed temporary or permanent residence, proven by your cédula, utility bills in your name, and your entries and exits from the territory, recorded by Migraciones. Travel and vacations do not break continuity, but absences of more than 6 consecutive months can cause problems.
   • Activity in Paraguay: profession, trade, or activity. If you're a freelancer with a US LLC, you're an international consultant based in Paraguay: your RUC and DNIT accounting prove the activity. For employees, the employment contract is sufficient. For retirees, the pension and proof of means of subsistence are sufficient.
   • Good conduct: Paraguayan police clearance certificate (antecedentes penales) and apostilled French criminal record extract, both clean.
   • Spanish: the Constitution requires knowledge of the official language. In practice, conversational Spanish at B1-B2 level is sufficient: the judge asks questions in Spanish at the hearing, and you must be able to answer them. Guarani is generally not required, but knowing a few words always makes a good impression.
2. Prepare the file:
   • Naturalization application form.
   • Paraguayan cédula, proof of residence.
   • French passport, identity, and original nationality.
   • Apostilled French birth certificate translated into Spanish.
   • Paraguayan police clearance certificate (antecedentes penales).
   • French criminal record extract, bulletin n°3, apostilled and translated.
   • Residence certificate, issued by the local comisaría or the Dirección General de Migraciones.
   • Proof of activity: RUC, tax declaration, employment contract, or retirement certificate.
   • Medical fitness certificate, issued by a Paraguayan doctor.
   • Two Paraguayan witnesses, citizens who attest to your residence and good conduct: friends, colleagues, neighbors.
3. Submit the file: to the Juzgado de Primera Instancia en lo Civil y Comercial of your domicile, Asunción for most expatriates. A Paraguayan lawyer is required: they draft the petition and conduct the procedure.
4. The hearing: the judge convenes a hearing where your two witnesses testify, where they can question you in Spanish about your life in Paraguay, your motivations, and your knowledge of the country—basic questions, not a university exam—and where the public prosecutor gives their opinion.
5. The judgment: the sentencia de naturalización. If favorable, it makes you a Paraguayan, with registration in the Civil Registry (Registro Civil) and the Ministry of Interior (Ministerio del Interior).
6. The citizen's cédula: after the judgment, you receive a new cédula with citizen status, which grants the right to vote, eligibility, and all the rights of a Paraguayan citizen.
7. The Paraguayan passport: with the citizen's cédula, apply for it at the Dirección General de Identificaciones of the Policía Nacional. Processing time is 1 to 4 weeks, cost is 200,000 to 500,000 PYG, or 28 to 70 USD.

Cost of naturalization

Item	Estimated Cost (USD)
Paraguayan lawyer (file and court representation)	~1,000-3,000
Sworn translations (birth certificate, criminal record)	~100-300
Apostilles	~0-50 (free in France)
Certificates (Paraguayan criminal record, medical, residence)	~50-150
Court fees (stamps, registration)	~100-300
Paraguayan passport	~28-70
Total	~1,300-3,900 USD

Naturalization costs 1,300 to 3,900 USD, mostly in lawyer's fees, for a procedure lasting 6 to 18 months after the required 3 years of residence. A modest investment considering the benefits.

Advantages of Franco-Paraguayan dual nationality

Paraguayan passport vs. French passport

Advantage	French Passport	Paraguayan Passport
Visa-free access	Approximately 190 countries, one of the most powerful passports in the world: EU, USA with ESTA, United Kingdom, Japan, Australia.	Approximately 140 countries: Mercosur, accessible with just the cédula, Latin America in general, and many countries in Asia and Africa.
Residence in Paraguay	Requires a resident cédula, with immigration procedure and renewal, see our page Paraguayan residence.	Permanent and unconditional right of residence. No renewal, no procedure: you are at home.
Mercosur Residence	90-day tourist access; permanent residence requires a procedure in each country.	Right of residence in Mercosur countries upon simple, simplified application: 2-year temporary, then permanent. Live and work throughout the region.
Voting rights in Paraguay	No, foreign residents do not vote.	Yes: presidential, legislative, municipal, and even eligibility for office.
Purchase of agricultural land	Legally possible, but cultural mistrust of foreign buyers exists in rural areas.	Facilitated access: the Paraguayan passport dispels this mistrust.
Paraguayan bank credit	Possible but more difficult, banks prioritizing citizens for real estate and commercial loans.	Facilitated access: treated as a Paraguayan, fewer documents, often better rates.
Consular protection	The French diplomatic network, one of the most extensive in the world.	The Paraguayan network, more limited but useful in Latin America, in addition to the French protection you retain.

Strategic advantages

• Geopolitical resilience: two nationalities, two safety nets. If France ever tightened its rules for expatriates, your Paraguayan nationality would be a fallback option. If Paraguay experienced instability, your French nationality would bring you back to the EU without a visa. A second passport is geopolitical insurance.
• Mobility: the combination of the two passports covers almost the entire planet. The French one opens up the EU, the USA, Japan; the Paraguayan one opens up Mercosur and facilitates travel in Latin America, where some countries impose fees on Europeans but not on Mercosur nationals.
• Transmission to children: your children born in Paraguay already have both nationalities, French by descent and Paraguayan by birth on soil. Having become a Paraguayan citizen, you also transmit Paraguayan nationality to your children born outside Paraguay. This is a heritage that no financial investment can replicate.
• Choice of passport when traveling: entering Argentina, Paraguayan passport or cédula, quick passage; entering the USA, French passport with ESTA; entering France, French passport, mandatory for French citizens; entering Paraguay, Paraguayan document, mandatory for Paraguayan citizens. General rule: the passport that offers the best access to each destination.

The very rare cases of loss of French nationality

The only scenarios provided by law

The loss of French nationality is exceptional and does not concern ordinary expatriates. The cases are exhaustively listed in the Civil Code:

Case of Loss	Civil Code Article	Description	Concerns an expatriate in Paraguay?
Voluntary renunciation	Articles 23-4 to 23-7	A French national who acquires a foreign nationality may voluntarily renounce French nationality, by declaration to the consul or the Minister of Justice. This is a voluntary act: France cannot force you to do so, and the government may even oppose the registration of the renunciation, particularly in times of armed conflict.	No, unless you yourself decide to renounce, which no one imposes on you
Forfeiture for terrorism or undermining the fundamental interests of the Nation	Article 25	The government may strip a dual national convicted of terrorism, treason, or espionage, without ever being able to create a stateless person. Exceptional procedure, a few dozen cases since 1945, mainly related to terrorism.	No, unless you commit crimes of such gravity
Loss by prolonged non-use	Article 23-6	Concerns a French national born abroad, with nationality by descent, who has never resided in France, owns nothing there, and has never exercised their civic rights: the authorities may note the total absence of connection. A very rare case, reserved for second and third generations with no ties whatsoever. A French national born in France who expatriates is never concerned.	No, improbable scenario for a reader of this guide
Annulment of naturalization	Article 27-2	If French nationality was obtained by fraudulent naturalization, false documents, sham marriage, concealment, the government may annul it within 2 years of the discovery of the fraud, with retroactive effect.	No for French citizens by birth

In summary: for a French citizen by birth who settles in Paraguay and becomes Paraguayan, there is no mechanism for automatic or involuntary loss of French nationality. The only way is voluntary renunciation, which nothing obliges you to do. Franco-Paraguayan dual nationality is safe, stable, and definitive.

Voluntary renunciation: to be avoided

If, hypothetically, you were considering renouncing French nationality:

• The procedure: declaration to the French consulate in Asunción or to the Ministry of Justice, with proof of another nationality, as France cannot create a stateless person.
• Possible refusal: the government may object to registration in certain circumstances, particularly in times of war. Refusals remain rare in practice.
• Consequences: loss of French passport, voting rights, visa-free access to the EU (you would need a Schengen visa to visit France), consular protection, and French social rights. An irreversible act, except for a subsequent long and uncertain naturalization.

Our position: never give up. Dual citizenship gives you the best of both worlds; there's no reason to choose only one.

Paraguayan Citizenship and Its Obligations

Rights and Duties of Paraguayan Citizens

Rights	Obligations
Right to vote in Paraguayan elections: presidential, legislative, municipal.	Voting is mandatory for citizens aged 18 to 75, Article 120 of the Constitution; penalties for abstention are rarely applied.
Eligibility for most offices, with the presidency reserved for native-born Paraguayans.	Military service theoretically mandatory for male citizens aged 18, with no practical application for naturalized adults as they are past the call-up age. See our guide to civic obligations.
Unconditional permanent residency, citizen ID card without status renewal.	Tax obligations identical to those of any resident: 8-10% IRP on Paraguayan-source income, territoriality for the rest.
Facilitated residency throughout Mercosur.	Respect for Paraguayan laws, like any resident.
Access to Paraguayan public office.	No jury duty: the Paraguayan judicial system relies on professional judges.
Paraguayan passport, approximately 140 visa-free countries.	Obligation to enter and exit Paraguay with a Paraguayan document, cédula or passport.

The Tax Impact of Paraguayan Citizenship

It's very simple to summarize: none.

• Before naturalization: IRP on Paraguayan-source income, 8-10%, and territoriality for foreign-source income.
• After naturalization: exactly the same. In Paraguay, it is residency that determines tax liability, not nationality.
• French side: France taxes based on tax residency, not nationality, unlike the United States. Your Paraguayan nationality entails no additional French tax obligations.
• No "Paraguayan FATCA": Paraguay has no equivalent of the US law that taxes its citizens worldwide. It taxes Paraguayan-source income, regardless of nationality.

Dual Nationality in Daily Life

Which Passport for Which Journey

• Entering Paraguay: Paraguayan passport or citizen ID card, Paraguay requires this from its citizens.
• Entering France and the EU: French passport, mandatory for French citizens, plus the added benefit of the EU queue at European airports.
• Traveling within Mercosur: Paraguayan passport or simple ID card, visa-free, as a citizen of the region.
• Traveling to the USA: French passport with ESTA; a Paraguayan passport requires a visa.
• Traveling to Asia: French passport, which offers broader visa-free access.

Renewing Both Passports

• French passport: renewable for life at the French consulate in Asunción, like in any consulate worldwide, without conditions of residency in France. Valid for 10 years for an adult, approximately €86, processing time 2 to 6 weeks.
• Paraguayan passport: renewable at the Dirección General de Identificaciones in Asunción. Valid for 10 years, 200,000 to 500,000 PYG, or 28 to 70 USD, processing time 1 to 4 weeks.

Common Mistakes and Misconceptions

Misconception 1: "Dual nationality is illegal in France"

False. France has recognized it since 1973, without any restrictions. Recurrent political debates about its limitation have never resulted in any law.

Misconception 2: "I have to choose between the two nationalities"

No. Neither France nor Paraguay requires it. The only exception concerns a few sensitive positions in French public service, diplomacy or high military command, which affect only a tiny minority of French citizens.

Misconception 3: "Becoming Paraguayan will attract the attention of the French tax authorities"

No. The acquisition of a nationality is not a tax event. The French tax authorities look at your tax residency and your income, not your passports. As a non-French tax resident, your Paraguayan naturalization changes nothing about your situation.

Misconception 4: "The Paraguayan passport is useless if I have a French one"

The French passport is powerful, but the Paraguayan one provides what it lacks: unconditional permanent residency in Paraguay, Mercosur residency on demand, local voting rights, easier access to Paraguayan bank credit, and geopolitical insurance. Together, the two are worth far more than each separately.

Misconception 5: "Paraguayan naturalization is difficult and long"

Compared to many countries, it is remarkably accessible: 3 years of residency versus 5 in France or the USA, no formalized language exam, a conversation in Spanish with the judge is sufficient, no standardized citizenship test, a cost of 1,300 to 3,900 USD, and a procedure of 6 to 18 months. One of the most affordable naturalizations in the world for a long-term resident.

Misconception 6: "I will have to renounce my French nationality during the ceremony"

False. The oath of allegiance to Paraguay, standard in any naturalization, contains no clause of renunciation of original nationality. You become Paraguayan in addition to being French, never instead of.

Should You Become Paraguayan? Cost-Benefit Analysis

For Whom Is Naturalization Recommended?

• Long-term expatriates, 5 years or more with no intention of returning: naturalization provides the security of unconditional residency, voting rights, and Mercosur access. If Paraguay is your home for decades to come, it's a logical investment.
• Mixed Franco-Paraguayan couples: becoming Paraguayan strengthens the bond with your spouse's family and culture, and creates a natural symmetry with your children, who are already dual nationals by birth. See our mixed couple guide.
• Entrepreneurs active in Latin America: a Paraguayan passport and Mercosur residency streamline business travel and company formation throughout the region. A concrete business advantage.
• Real estate investors in Paraguay: facilitated bank credit, seller confidence in rural areas, simplified procedures. See our real estate investment page.

For Whom Is It Not Necessary?

• Temporary expatriates, 1 to 3 years with planned return to France: residency is sufficient to live, work, and benefit from tax territoriality.
• Digital nomads who change countries regularly: naturalization is premature, and the 3 years of residency may never be met.
• Those who do not yet have 3 years of residency: the condition is strict, with no shortcut outside of marriage to a Paraguayan. Wait until you meet it before starting the procedure.

Conclusion

No, you do not lose your French nationality by becoming Paraguayan. This myth is debunked by Article 23-1 of the Civil Code, which states that the acquisition of a foreign nationality does not entail the loss of French nationality, and by practice: thousands of French people live as dual nationals around the world, and yes, as Franco-Paraguayans. Both countries recognize dual nationality without restriction.

Paraguayan nationality is accessible—3 years of residency, 1,300 to 3,900 USD, 6 to 18 months of procedure—and it offers concrete advantages: unconditional permanent residency, Mercosur access, voting rights, bank credit, and a second passport as geopolitical insurance. Combined with French nationality, it's the optimal alliance: approximately 190 visa-free countries on one side, Mercosur on the other, tax territoriality, no inheritance tax, and dual consular protection.

The only way to lose French nationality is to voluntarily renounce it, which nothing justifies. Your French nationality is a lifelong asset, unalterable by time, distance, or the acquisition of another citizenship. In Paraguay, you are home. In France, too. And with two passports, the whole world is a bit more accessible.
