My teenagers and I are planning to move to somewhere near Calais in June. we are already approved for a French mortgage, have all pets paperwork done and just need the visas. My question is what kind of visas do we need if I am retired and will not work, but the kids are 20, 18 and 16? They do not plan to work now but what about later on? And what about having an address for the visas as we do not plan to choose a house until our arrival?
