Paraguay to Screen Traveller Biometrics at Borders Under New U.S. Accords

Paraguay and the United States signed two security agreements on 19 October 2026 that will bring live U.S. satellite data on suspect aircraft to Paraguayan forces and biometric screening of travellers at the country's official border crossings. The accords were co-signed in Asunción by Paraguayan Foreign Minister Rubén Ramírez Lezcano and U.S. Deputy Secretary of State Christopher Landau. No date has been announced for when either measure takes effect.

Key facts

• 19 October 2026: two accords signed at Paraguay's foreign ministry in Asunción.
• U.S. satellite intelligence will be streamed live to Paraguay to help detect and intercept suspected drug-trafficking aircraft.
• The U.S. will deploy PISCES, a biometric border-screening system, at Paraguay's official border crossings, with training for local personnel.
• No launch date has been given for the satellite feeds or the PISCES network.
• The agreements build on a Status of Forces Agreement signed on 15 December 2025.

What changes at the border?

Under the Memorandum of Intent on Border Security, Washington will deploy PISCES — the Personal Identification Secure Comparison and Evaluation System — at Paraguay's official border crossings. The system matches travellers' biometric data against international watchlists in real time, flagging persons of interest as they attempt to cross.

The accord includes hands-on instruction and knowledge transfer for Paraguayan border staff. It has not been stated which border crossings will get the system first, or when the rollout begins.

What is the other agreement?

The first instrument, an Exchange of Notes on aerial interception of civil aircraft, sets a legal and operational framework for Paraguay to act against suspect planes under its own laws and international aviation standards. Ramírez Lezcano said Paraguay will receive live data streams from U.S. satellite systems, giving it a real-time picture of suspicious aerial activity it did not previously have.

The foreign minister stressed that the arrangement involves no joint operations on the ground and does not change Paraguay's domestic legal framework. Interdiction remains a Paraguayan mission, with the United States providing the targeting picture. The U.S. Embassy in Asunción said the accord "will strengthen Paraguay's capacity to monitor and protect its sovereignty against suspicious flights."

Why is this happening?

Paraguay's Interior Minister Enrique Riera described the Chaco — the sparsely policed western half of the country bordering Bolivia and Argentina — as an open corridor for illicit air traffic in late 2023, citing more than 1,500 clandestine airstrips used to offload cocaine arriving from Bolivia and Peru before it moves east toward Brazil and on to European markets. Brazilian security forces operating in Paraná state seized 156 tonnes of drugs traced to Paraguayan territory in the first half of 2026 alone.

What this means for travellers

Anyone crossing Paraguay's official borders should expect biometric screening once the PISCES system is deployed, with data matched against international watchlists at the point of crossing. The source gives no start date, so travellers cannot yet tell when this begins. Anyone planning to cross a Paraguayan border should check the latest entry procedures before travelling.

What happens next

The operational timeline for activating the PISCES network and integrating satellite feeds into live interception protocols remains to be seen and is being watched by security analysts and neighbouring governments. The agreements sit on top of the Status of Forces Agreement signed by Secretary of State Marco Rubio and Ramírez Lezcano in Washington on 15 December 2025, ratified by Paraguay's Congress in March 2026 and signed into law by President Santiago Peña on 11 March 2026. Landau met President Peña during the visit before travelling on to Buenos Aires.
