Any help would be beyond appreciated. I will explain my situation as QUICK as possible.
1. Wanted to move to finland for over 5 years, I have been learning finnish, I have had a Finnish girlfriend, lots of finnish friends and have visited. So not to waste anyones time! I do not need advice regarding the culture 'shock' or language (I am continually progressing so no worries there).
2. I have had an internship set up in finland for APPROX 1 year.... It is unpaid but allows for fantastic learning opportunities.
3. around (lets say 6 months ago) I began the process of applying for a masters in HKI.... I got accepted say 2 months ago.
NOW
1. KELA... from what I understand on their official website, I COULD be entitled to some form of benefits. However many friends have explained (essentially) kela wont touch me until ive been there for 2 years. BUT many have urged me there are 'ways around it' and I should try.
2. my primary reason for coming (aside that ive wanted to forever) is to work at this internship... It benefits young finns lives and I will be both learning and doing good

PLEASE trust me when I say I have genuine intentions. I really do, I wouldn't have been learning the language / socialising with finns and obsessing / moving towards the idea for years JUST to come and be a 'leech'... but the reality is... im POOR. and I initially at least need some help / income!
I have tried to find a job there, but this will be much easier once im actually there!
ANY advice would be astoundingly helpful... I have approx. 3 weeks to 1000% confirm im doing this masters and thus far im TERRIFIED I realllly don't know what to do.
By the way, im English with no family ties in Finland x
