im having a KSUViolet06 kind of day, minus the magenta font.
i agree with k_s: work on making your current chapters strong so your case for expanding is flawless. you say you go to school in NYC but your official website only shows 2 NY chapters, neither being in the city.
which is irrelevant. focus on your potential as a member, then as a chapter, then as an organization in expansion.
Agreeing with LatinaAlumna, expansion is a two-way street: sure, you (and your fellow members) want to come to other campuses, but how do you know said campuses want you? the need and the want has to exist, from faculty and student body. it requires a lot of research and time.
