Paraguay Citizenship & Naturalization: The Complete Guide (2026)

Citizenship is the final step after residency. Once you have held permanent residency for at least three years, you become eligible to apply for a Carta de Naturalización before the Corte Suprema de Justicia. This is a judicial process — not an administrative one — and approval is at the discretion of the Court.

A successful naturalization grants you full citizen rights: the ability to vote, hold a Paraguayan passport, and act as your own legal representative without the restrictions that apply to foreign residents. In practice, citizenship also removes the residency-maintenance obligations attached to your permanent card — you are a national, not a guest.

The process is not automatic. You must demonstrate ties to Paraguay, pass a basic language evaluation, and submit a substantial document file. The Court verifies migratory records, criminal history, and your actual connection to the country before issuing the Carta.

Paraguay requires basic proficiency in Spanish or Guaraní for naturalization. This is not a formal standardized exam — the judge evaluates your ability during the personal appearance before the Court Secretariat. The threshold is functional: enough to hold a basic conversation, understand simple questions, and express yourself on everyday topics.

Some judges may also ask basic questions about Paraguayan history, geography, or the Constitution. There is no published syllabus — the evaluation is informal and at the judge's discretion. If you have lived in Paraguay for three years and interact in Spanish daily, this is rarely the barrier. If you don't speak Spanish yet, invest in lessons early in your permanent residency period.

Paraguay's Constitution (Art. 149) does not recognize dual nationality for naturalized citizens. On paper, you renounce your original citizenship when you take Paraguayan nationality. In practice, Paraguay has no mechanism to enforce this renunciation and does not check or communicate with your home country.

Whether you actually lose your original citizenship depends entirely on your home country's laws — not Paraguay's. Many countries (Spain, the United States, the United Kingdom, most EU members) allow their citizens to hold a second nationality regardless of what the other country requires. Some countries (Germany, Japan, and others) may require you to renounce under specific conditions.

The practical advice: check your home country's rules on dual nationality, not Paraguay's. For most applicants, Paraguayan naturalization does not result in losing their original passport.
