Do you have income and savings somewhere? A landlord needs assurance that the rent will be paid on a timely basis. That's why a co-signer is usually required. If you have sufficient assets to guarantee the rent and can show it on paper, maybe you have a chance? What's wrong with getting a co-signer? Even home buyers need one occasionally.
Sincerely good luck with your studies. Education is hard enough without having to worry about housing.
