I am an international student. How can I pay off debt?

My suggestion will be first of all; you should contact your embassy. Seek help from them. More than debt payment options, you need legal help right now.

International students cannot work or earn money....it is part of the rules of their VISA. in some circumstances they can work on campus. When you come to school in the US, you are expected to have the funds to support yourself. Calling an embassy will not change that.
