The schools that provide loans to internationals without a co-signer is a fluid thing -- since the 2008 crisis when Citigroup became a penny stock then (they were the bank lender for the top b-schools providing private loans), they pulled the plug, leaving the b-schools to scramble to find alternate ways. Not sure if all of them have (I believe all the top 8 except for Columbia -- and maybe Columbia has since managed to provide it as well.
What you'll have to do is contact each school directly, as this is something that is still a fluid process.
Now, if you're asking about scholarships -- you'll have to look at schools outside the top 30 to be honest with your profile. You're not getting free money from top schools abroad.
