E2 Visa Dependent students question!!!

I’m applying to Emory University… and they say that they need financial certifications for international students … but they do mention “if you are on any other type of visa (such as E, H, or L), which may not require you to be issued an I-20, please contact our office at 0011.404.727.6036.” - and currently I am not able to reach them… can somebody with experience please help? (i know i should make a different forum on this but… does Syracuse University require one for E2 dependents? thanks)
