In 2007, Prince Louis worked in forestry management for the Administration of the Assets of the Grand Duke. In 2008, he decided to take courses at the Miami University Dolibois European Center (MUDEC) in Luxembourg. He then spent two years in the United States, where he completed a training course in Aeronautics, granting him a private pilot licence in 2011. Afterwards, Prince Louis moved to the United Kingdom to continue his studies. In 2014, he obtained a degree in Communication at Richmond, the American International University in London.
