I screwed!!

Long story short after graduating from high school I wasn't sure what i want to do in life and decided to pursue career in finance too late so I took a GAP year and applied to Target universities In EU (Im from non-eu country and my diploma dosen't recognized by UK and I can't afford bachelor In USA) but because of my dumbass I now figure out that I can't study in Bocconi because Italy doesn't recognize my diploma (I had to have a specific document which is now too late to get) even though I got accepted to BIEF.

Now, I don't know what to do... I'm still waiting for RSM and SSE but neither are as good as Bocconi and I'm not sure they will be good for non local/EU student. I seriously don't know what to do now. In case I got accepted from RSM/SSE I'm planing to attend but if that fail aswell what should I do?

1. Study CS in Poland (maybe transfer to NL after 1st year)
2. Study CS in USA (Mid level school, I'm not sure If I manage to get a sponsoring Visa for H1B from this school)
3. Take second GAP year and get in Bocconi (mean time I can study Italian/first year class)

If I study CS in Poland would that be a career killer for consulting/IB ?

essentially I know that getting job In IB/S&T/ER/MBB is almost Impossible after bachelor for EU applicants and I will most likely have to do a master degree In UK/USA so does what I study or where I study my bachelor would be important for master degree?

If I take a second GAP year, would companies/universities (for master) know it? I'm currently 18 btw.

My career wise target would be 1) IB in UK/USA 2) MBB in Middle East 3) S&T/ER in UK/USA

I'm open to any kind of suggestion!
