Reclaiming Luxembourg Nationality



In 2008 the Luxembourg Government allowed all Luxembourg Citizens to obtain double (or multiple) nationality(ies) without having to renounce their current Luxembourg Citizenship. This new law is more elaborate than the previous double nationality law, which had only allowed double nationality from birth.


The Luxembourg government opened a window from 2008 to 2018 to allow adults who had lost their Luxembourg nationality and Luxembourg descendants (with a direct maternal or paternal ancestor who held Luxembourgish nationality on January 1, 1900) the right to reclaim Luxembourg Nationality .


You have until December 31st of 2018 to put in your application with the Ministry of Justice for the “First Step: receiving the Certificate that you have a Luxembourg Ancestor” (in French this is called “Certificat d’Aïeul”), and as of April 2017, "The Second Step must be completed by the 31st of December 2020, where you must sign, in the presence of a civil registrar, a declaration to reclaim Luxembourgish nationality."

Luxembourg Genealogy Resources: Getting Started (University of St. Thomas)

A guide to conducting Luxembourg genealogy using the the resources found in the Bach-Dunn Collection at the University of St. Thomas
Quoted from their website: "The Department of Special Collections houses one the largest collection of Luxembourg-related material in North America -- over 3,000 books, periodical volumes, maps, and rolls of microfilm.  Much of this material is of potential use to the genealogist.  Resources housed in the Department emphasize "Luxembourgers in Luxembourg" somewhat more than "Luxembourgers in the United States."  Other than the immigrant generation, you probably will need to seek resources on your American Luxembourg ancestors elsewhere."
