I wish I can find some answers or tips here that google has concealed. I am an undergraduate student in Italy and planning to move to the UK next year (Pakistani Passport), but whilst that I’d also like to maintain a long term Schengen Visa because I travel a lot and also my boyfriend is from Germany and go there often to see him. Our relationship is not registered anywhere so it is unofficial for fitting the few given criteria and I would like to find out if I can fit in some category to apply for a long term visa and not have the pain to apply for short term visas every once in a while. Does anybody have any experience on that? I’m basically just trying to find a way to have one leg in Schengen and the other in the UK. Many thanks.
Generally speaking, Schengen visa with long validity and multiple entries are given after a few visits on shorter, single-entry visa without overstays or incidents. Your previous Italian visa should count in your favor.
It might become problematic if your ties to your place of residence (the UK) become weak.
In my experience (with over 6 multiple entry schengen visa's with Sri Lankan passport), the more you traveled to and out of the schengen zone the higher the chance of applying and getting a long term visa. I visited my gf in Budapest so many times, and actually ended up getting a residence permit for "other purpose" by showing our bank accounts, employment etc in Hungary. But I didn't renew it as I have to come back home often for work (since there is a permit stipulation which states I can't be out for more than 3-6 month per period, and I couldn't obviously fulfill that due to work and other travel). So I simply ended up applying for a long term 3 year visa and got it. Again with a letter from my gf, both our employment docs. Wasn't an issue, and got it approved in 5 working days due to my visa history.
