This question already has an answer here:
My SO and I are currently staying in France under the country's visa long séjour, essentially a 1-year visitor visa. If we return to Europe after leaving when the visa expires we would naturally be covered by the Schengen visa for 90 days, which also begins the 180-day period. How do the rules for these two visas interact? For example, if we applied for another long séjour to begin at the end of our 90-day Schengen visa, does the Schengen period reset 90 days within the long séjour period? Will the French authorities frown on having visa types overlap like this? Our goal is to travel for around 2.5 years in Europe and then return home. We're American and can prove means and lodging for the entire period.
