I have already travelled to schengen area once on a single entry Schengen visa. I am now trying to apply for a schengen visa with the intention of making several short trips to the schengen area.
My plan is to go to France, Belgium, the Netherlands, Germany, Spain and Portugal in the next 6 months.
Which of the above embassies is most likely to provide a multiple entry visa? I can then tailor my plans and apply to that embassy to ensure I get a multiple-entry visa.
