Overview
- A change in the 2022 Ley de Memoria Democrática and a Justice Ministry instruction triggered a mass of nationality requests and by the deadline that closed on 22 October 2025 roughly 2.4 million consular appointment requests had been logged, with government projections suggesting the external electoral register (CERA) could approach about five million people.
- Consular systems are overwhelmed, with the Buenos Aires consulate reporting about 645,052 appointment requests and only around 30,000 cases resolved to date at a pace near 1,000 files a month, creating long backlogs that delay verification of new nationals and their voter registration.
- Political actors have reacted: Vox has asked the Central Electoral Board to bar CERA voting, the PP is pushing for close oversight and studying structural options, and some parties plus the CGCEE are promoting a separate external constituency estimated to elect seven deputies and five senators.
- Analysts warn even a small number of new external voters could change outcomes because 13 congressional seats in the last general election were decided by margins under 3,000 votes, and newly naturalized citizens can choose the Spanish province where they register to vote.
- Longstanding integrity concerns — including poor identity verification and reports of deceased people on the CERA — combine with documented PSOE outreach in Argentina and Uruguay offering free help to applicants, raising scrutiny of partisan mobilization and increasing pressure for electoral reform.
