Luxembourg Citizenship Eligibility Is Changing on December 31, 2025. Take Action Now
Our mission: We help create bridges between the Americas and Europe.
At LuxCitizenship, we turn heritage into opportunity. Since 2016, we’ve been helping individuals with Luxembourgish ancestry reclaim dual citizenship, unlocking new possibilities for personal and professional growth.
Our track record speaks for itself—as of March 2026, we have successfully helped more than 3,200 American clients obtain proof of Luxembourg citizenship, with hundreds more on their way. Our clients represent 16.8% of all new Luxembourg citizens living in the United States in 2025..
But we are more than a citizenship service. As we continue to grow, so does our mission. With well over 40,000 new Luxembourg Dual Citizens across the U.S., Brazil and Argentina, we’re dedicated to building a thriving, connected community fostering meaningful connections between these new citizens and Luxembourg.
We reinvested in community-building, sponsorships, and charitable initiatives that maintain Luxembourgish history and directly impact Luxembourg Dual Citizens today.
We wrote and produced the documentary film Lëtzebuerger an Argentinien. We’re working to strengthen cultural ties, support local organizations, and create a global network of Luxembourg citizens proud of their roots and united in purpose.
LuxCitizenship is an LGBT-owned and operated company. We are a member of the Luxembourg American Chamber of Commerce, the National Gay and Lesbian Chamber of Commerce and a patron sponsor of the Association of Luxembourgish Citizens in Brazil.
In addition to Luxembourg, we also offer EU ancestry dual citizenship services for more than 20 other European countries through our sister project Citizenship.EU launched in August 2025. And we offer residency services in Brazil, whether through digital nomad or investment, through our project StartBrazil that launched in March 2026.

Daniel Atz
Founder
Daniel Atz recovered Luxembourg citizenship in 2014. He obtained his dual citizenship through his great-grandmother Marguerite Kruchten from Esch-sur-Alzette who moved to Leavenworth, Kansas after World War I. Daniel is originally from Omaha, Nebraska. He holds a BA in International Studies from Loyola University Chicago and studied European Business Law while at the École Supérieure du Commerce Extérieur in Paris, France. Daniel is a fluent French, Portuguese, and Mandarin speaker and also speaks some Luxembourgish. Before LuxCitizenship, Daniel worked for the Belgian-American Chamber of Commerce (BelCham). There, he brought over 200 Belgian small businesses and startups to set up and grow in the United States.
Daniel has been repeatedly featured on Luxembourg national television (RTL) for stories relating to his dual citizenship. In 2017, through a stroke of luck, Daniel’s long lost Luxembourgish family saw a TV program featuring Daniel holding a photo of his great-grandmother. RTL follows Daniel on his journey as he came to Luxembourg to meet his long-lost family for the first time. Read Daniel’s article on the experience or watch the featured television program.

We are committed to creating a strong, connected Luxembourg dual citizen community. We’ve sponsored, organized, and participated in Luxembourg-related events across Brazil, Argentina, and the U.S., collaborating with organizations like the Luxembourg-American Chamber of Commerce in New York, ACLUX in Brazil, and the Argentina Luxembourg Association. We’ve held events across the U.S., including in Minneapolis, Chicago, and New York, where our last gathering at the Luxembourg Consulate had 55 attendees. We’ve also organized a tour of Luxembourg for 35 clients. Our programming continues to grow, nurturing the bond between the Luxembourg diaspora and their ancestral home.
Recently, we launched a growing registry of 20+ businesses owned by Luxembourg Dual Citizens, with many more to come. In addition, our LinkedIn networking group continues to grow, fostering stronger business connections and collaboration among dual-citizen professionals. Our vision is to broaden this network, creating even more opportunities for Luxembourg Dual Citizens to connect professionally and thrive globally.
Since 2018, we’ve conducted annual demographic research studies on the Luxembourg Dual Citizens, expanding from U.S. dual citizens to include Brazil and Argentina. Our 2023 survey had 1,174 respondents. These research studies are the first systematic research project about these new citizens and are made to provide insights about Luxembourg’s newest citizens. We also analyze Luxembourg government data to track population growth, migration patterns, and election data, focusing on votes from abroad. Our research has been featured by various global media outlets including CNN, RTL and Luxemburger Wort.
We have published over 150 blog articles in both English and Portuguese, providing information for Luxembourg Dual Citizens that doesn’t exist anywhere else.
We create video content relevant to the Luxembourg diaspora. Our YouTube channel features more than 50 videos, including interviews with dual citizens, tours of Luxembourg, and information on the country’s culture, history, and citizenship. Building on this success, we’re launching feature-length films, starting with Lëtzebuerger an Argentinien, a documentary on Luxembourgish migration to Argentina and the reconnection of their descendants with Luxembourg today. The film premiered in November 2025.
LuxCitizenship advocates for the rights and interests of Luxembourg dual citizens. We engage with policymakers, ensuring informed decisions on key issues affecting our community. Our efforts have focused on matters such as language integration, FATCA regulations, non-binary gender recognition, and rights for children born through surrogacy to same-sex parents.
We are a digital-first organization focused on innovation, data privacy, cybersecurity, and compliance. We have built every aspect of our business, such as our website and project management tools, in-house. Our innovations include an automated Luxembourg Citizenship Eligibility Test, delivering 1500+ automatic eligibility assessments per year with 97% accuracy.
