My grad department isn't offering courses listed in the catalog. What do I do? I am a graduate student of Industrial Engineering at a US university. The IE grad department has about 11 graduate level courses listed in their catalog. However, insofar they have offered only 2 of those courses. One in fall, and one for the upcoming spring semester. 

I spoke with students who are graduating this year learned that they have been in the same situation. The department has been offering the same two courses repeatedly for the past couple of years. Courses with which my interests align aren't being offered at all. With no choice, I am having to take up undergrad courses (one level lower) to keep up with credit requirements. I wanted to know whom I could approach in such situations. Who should I contact? 

My options are limited since I am an international student. Moreover, my tuition fees are higher, and for that cost, I feel my educational needs aren't being met justly.

How can I approach this problem? What are the possible solutions?
In most science-technology-mathematics-engineering departments in the U.S., there are many more courses in the catalog than are offered in any year. There are typically pressures (from above, or from faculty) to offer fewer, rather than more, courses, so things may default to reduced graduate course offerings. Nevertheless, if many grad students explicitly request (to the department) a given course, this greatly increases the chances it'll be offered. Certainly if you don't ask, things will probably continue to be the same.
