Questions about spring weeks in London for IB

Hello,

I hope you are doing well. I will be starting my bachelors course (BESS) at Bocconi University in September as a non-EU first year international student. I will also be applying to spring weeks at banks in London. 

-Is being a non-EU student a huge setback when it comes to applying for spring weeks in London?

-I am pursuing a 3 month internship in the finance department of a diversified firm but most revenue comes from IT, and it is a top 100 company in one of UAE/KSA/Qatar. I have read that it is best to apply as soon as possible for spring week internships. Should I wait to join student organizations pertaining to finance at Bocconi and wait till like mid-late September to apply or should I apply as soon as banks start opening applications?

-Should I include an environment related club in my school which is completely unrelated to finance but involves raising a large amount of money by pitching to the board of directors at my school district in my CV?

-Is anyone who is currently in the industry willing to read over my CV and point out potential things that may get me dinged?

-Apart from the internship I am pursuing, is there anything else I should be doing in my summer break to maximize my chances of getting a spring week?

Thank you so much!
