Interest should be included in your filing as income; it does not bar you filing tax. So far my little knowledge about 1040 NR, you will not be able to get standard deduction and sometimes school may not let you know  (if helping to file taxes to foreign students) that you can itemize your mandatory expenses as NayaSadak mentioned, which will lower down your tax liability and may be able to get some refund.

Please, do some research on itemized deduction you are allowed.
