Hello Everyone, I just got admitted to GWU's Masters Program in Global Health. I am an international student and I have no idea how to approach about asking for GA / TA/ RA. I wanted to see what others international students know about getting any of these assistantship. When I emailed the admissions, they just asked me to contact the department which I did, but have not heard back from anyone. I would like to know how much of international students at GWU are given funding for masters because with out funding I am going to have to make a different choice. Any kind of suggestions would really be appreciated. Thanks!
