The numbers are in, and they tell a remarkable story: 3,574 new Luxembourg citizens were added in the United States during 2025—the largest annual increase we’ve ever tracked. But the reasons behind this surge aren’t what you might expect.
Luxembourg’s Ministry of Justice has released its Nationality Statistics Statistics for 2025. In total, 8,224 people acquired Luxembourgish citizenship last year through all pathways combined, a 14% increase from the 7,214 who obtained citizenship in 2024.
You might assume this bump came from a rush to beat the December 31st, 2025 Article 89 deadline to recover citizenship through an ancestor alive on January 1st, 1900. The plain truth? It didn’t. But there’s much more to this story.
Top Countries of Origin
The top five countries of origin for new Luxembourg citizens remained unchanged from 2024, though most saw significant increases:
Brazil and the United States both rebounded dramatically after 2024, which was among the lowest years on record for both countries.
Article 89: The Final Deadline’s Impact
Of the 8,224 citizenships processed in 2025, only 377 adults obtained citizenship through Article 89—the pathway for recovering citizenship through an ancestor alive on January 1st, 1900. While this represents a significant increase from 163 in 2024, it falls far short of expectations. As of January 1st, 2025, Ministry of Justice data indicated that 6,668 adults still had until December 31st, 2025 to submit a recovery declaration: 681 Americans, 2,893 Brazilians, and 3,094 others.
However, context matters. Luxembourg law requires four months to process Article 89 applications, meaning these 2025 statistics actually reflect applications submitted between September 2024 and August 2025. They also exclude minor children entirely.
Because of this processing delay, the final count of people who recovered citizenship through an ancestor alive in 1900 won’t be confirmed until late January 2027. We’ll begin to see clearer numbers by mid-2026 through data from the National Registry of Physical Persons (RNPP).
From our own experience, client travel to Luxembourg was lighter over the summer compared to previous years, but the final months of 2025 saw a dramatic surge. The Bierger-Center’s citizenship appointments were fully booked for November and December—something that hadn’t happened since late 2022, before Parliament extended the original Article 89 deadline. We expect the 2027 data release to show significant increases in recovery applications.
The Real Story: Article 7 Drives the Surge
While the Ministry of Justice statistics show meaningful growth, the most striking figures come from elsewhere. According to the National Registry of Physical Persons (RNPP), 1,267 new Luxembourg citizens were registered in the United States from October through December 2025 alone—the largest three-month increase on record. This dwarfs the already substantial 798 from July through September. The only comparable period was January through March 2023, when 1,206 new citizens were added following the perceived 2022 Article 89 deadline (Parliament didn’t vote to extend it until December 21st, 2022, so most Americans had already applied).
Here’s what makes October through December 2025 different: this surge cannot be attributed to the December 31st Article 89 deadline. Those applications take four months to process, and the RNPP tracks granted citizenships, not applications. The Ministry of Justice shows only 588 Americans obtained citizenship through Articles 23 and 89 combined throughout all of 2025—less than half the October–December increase alone. Even accounting for minor children (our research consistently shows 0.32 children per adult applicant, adding roughly 188 citizens) and the rare spousal citizenship under Article 28 (only 10 total in 2025), the math doesn’t work. The remaining increases must come from Article 7 applicants—people who were born Luxembourg citizens without knowing it.
Because the Ministry of Justice doesn’t classify Article 7 cases as “applications for citizenship”—because these people have always been citizens, even without knowing it—they publish no statistics on this pathway. Yet combining all of the 2025 RNPP data with ten years of our own research, we estimate that approximately 2,986 Americans obtained their first certificate of Luxembourgish nationality under Article 7 during 2025.
Looking Ahead
It remains difficult to predict Article 89’s ultimate impact on 2025–2026 numbers. We know the Bierger-Center was fully booked through year-end, but we estimate Brazilian applicants drove most of that demand. As of September 1st, 2025, there were still 638 Americans, 2,621 Brazilians, and 3,047 others theoretically eligible for Article 89.
Regarding those 638 Americans: based on our decade of experience with over 3,200 American applications, we believe the majority have either passed away or abandoned their applications entirely. Social media and image searches tell a different story for Brazil—a very large number of Brazilians traveled to Luxembourg from September through December 2025 to apply in person.
LuxCitizenship by the Numbers
Of the 58 American adults who reclaimed citizenship under Article 89 in 2025, none were LuxCitizenship clients—we had submitted all our Article 89 cases by the end of 2022. However, our clients represented 25% of the 530 American adults who obtained citizenship under Article 23 last year.
Across all pathways, LuxCitizenship clients accounted for 16.8% of all new Luxembourg citizens living in the United States in 2025.
Looking forward, we started 904 new applications during 2025, the majority still in the document collection phase. The pipeline remains strong as Americans continue discovering their European heritage.
