<human>: The last thing I need to apply for the visa is proof of return date from Spain, but how do i prove that I' coming back if I dont wanna buy the ticket AND THEN apply for a potential to be denied? ( i doubt i would but you never know)
I'm thinking there has to be an easy, risk free way of doing this, without paying extra for a refundable ticket. 
And what if you dont know when you're coming back.  I spose i did read somewhere they wrote " dont buy your ticket until you have your visa" but then it could be too late and the prices would be higher.  But then i guess you could say i shouldve prepared sooner.
