Sasa Songo,
Well, my advise is, look elsewhere other than the UK! Firstly, you will be charged a hefty international fees (3 times higher than a local/EU student) and you still need a roof under yourself and food! My advice would be the Schengen space (France, germany, spain, denmark, Norwar, sweden etc) since they do not charge international fees (all research students are treated equally) and rather more support from the institutions.
Regards:-)
