My maternal grandfather as well as paternal grandmother were both French Nationals as young adults unbeknownst to them, as they qualified under the Huguenot’s right of return/nationality mandate that was written in the French Constitution before my grandparents’ birth and until 1945. The revoking of this right to return in 1945 means that my grandparents’ National Status was withdrawn in their young adult years. But, really what I am wondering is if whether when the law was still in effect, were my grandparents technically citizens? I want to know if they are French citizens in case I am able to claim citizenship by descent through them. What is the difference, if any, between the label “National” and “Citizen” in this? Thanks.
