can my cousin be my financial granter/sponsor For studying in Hong Kong University?

I am from Bangladesh and got half tuition fee scholarship and grant from an university of Hong Kong. But rest of the tuition fees and maintenance cost will be provided by my cousin who lives in USA.
Will it cause any problem to get Hong Kong study visa as my cousin is second blood relative? Because of this confusion I am delaying to accept the offer and paying registration fee.

Can anyone please clarify this matter?
