I have a question about French residency which is slightly complicated. We are a South African family who entered France on long stay visas. My husband simultaneously moved to the UK head office of the company he worked for in SA, on a UK work visa. Under normal circumstances (pre-epidemic) he was commuting weekly to the London office, where he works 4 days per week and returns to our home here for 3-day weekends.
My questions are as follows :
as a South African citizen and a UK work visa holder, is he a frontalier ?
is he entitled to an S1 form so that we can be registered on the French healthcare system, considering he has a NI number ?
we would like to ultimately obtain French citizenship, which will be fine for me as I will have been living here continuously, but my husband will have been roughly splitting his time between the 2 countries. Are there allowances made for frontalier workers in terms of obtaining citizenship ?
Thank you in advance for any light you can shed on these questions.
