I am planning on retiring in France (next year), so I have been doing much research on my options for requisite (to apply for my visa de long sejour) health coverage (HC). At this point I well understand my situation for this initial requisite HC. However I have frequently come across mention of a "5 year rule" pertaining to permanent legal residency in France (which is my intended goal). Typically such mention goes like: "..... the 5 year rule under which if you have been legally resident and fully covered for HC for 5 years, and you have no other cover such as via an S1, then you become entitled to join the health systems without further qualifications" This would nominally eventually apply to me, yet I have only found such anecdotal mention. Could someone explain this "rule" in more detail as to whom it categorically pertains, and under what circumstances? Or, point me to some official description? I am a non-EU citizen, with no previous history of residing in, working in, or contributing to cotations, etc. in France. many thanks,
