I am trying to apply to Western Kentucky University and I am an international student but it asks for SSN? - university of kentucky hats

I am trying to apply Western Kentucky University, and I am an international student exchange, but requires no social security number. Well, I have my Belize, but I'm sure that if you work ... I do not want something that could ruin my chances. What should I do? I've tried to cook the international mail, but I am still waiting for a response.
