Alexandre GILLIOEN

Partner & Founder

After having lived  in foreign cities for many years and countries (Brussels, London, Washington, Douala), I decided to create my practice in Lyon because I consider this city as full of opportunities and ideal for a new start. Lyon, a city on a human scale located near Switzerland and Italy, is also a welcoming place for those of us who decide to come and put down roots here. After four years of experience in the field of immigration, I handle on all aspects immigration law.


Senior Associate

I became interested in immigration law during my 6-month internship at the Prefecture du Rhône. This immersion in the heart of the administration allowed me to discover the mysteries of litigation relating to immigration law, and to take the real measure of the specificity relating to this matter. This experience has been of considerable enrichment, which I put today at the service of our clients.



After a first experience in the field of Labour Law, I became interested in Immigration Law. Because of my first job, I have been very sensitive to the case of immigration workers.  Since I am part of the team, I am now aware of all the difficulties one may face when trying to immigrate to France. That is why I am here to help them in their project using all my abilities.
