Strayer University Delta Sigma Theta

I'm going to Strayer University in the spring, can I walk Zeta Phi Beta or another community? 3

For the most part, I agree with the poster above. It depends entirely on the student union and whether the student union is active / inactive / non-existent on your campus. See my answer to a similar question, can a graduate chapter hire graduates? over here:

Strayer University Delta Sigma Theta

From the Delta Sigma Theta Sorority, Inc. National website:
Any student currently enrolled in a college or university that has an active branch on campus or in the city may apply, provided the college or university in which the student is enrolled is recognized by the U.S. Department of Education. Recognized by the body or faculty. Accreditation Board.
So if Strayer University is nationally recognized and accredited, you can enter the local graduate chapter, but I don't think the school visits their website.
I know you said Zeta Phi Beta, but I'm sure it applies to all NPHC student bodies. You can also find more information on national websites. Help for example!
