ICaSNg:
I'll advise you use a single statement of account. Make sure the balance in this account covers the balance of your tuition fees, living costs and enough to cover for your sponsor to cover for his expenses- this is logical.
I won't advise a pension statement unless it complements the balance on that account e.g don't use a statement of #100,000 monthly and show a balance of #8m. It does not add up.
Another thing is , don't dump huge amounts in any account you'll use .
good day, I want to ask if my maternal aunt can be my sponsor when applying for visa and what is the minimum balance that should be in her account for it to fly.
