Are you the only South Asian Fraternity on campus or are there other South Asian Fraternities on campus (i.e. recruiting from the same pool of students)?
I went to a very large school with a very large Greek community, and we only had one South Asian Fraternity. We also had one South Asian sorority, two Asian-interest fraternities, and two Asian-interest sororities.
From my experience, the girls that came to college already knowing about sororities were the ones who were looking for a NPC sorority experience. And therefore, my sorority wouldn't have been right for them. So the pool of students we were recruiting from were the girls that either didn't know what sororities were or girls who had only heard the stereotypes. As such, recruitment for us can sometimes be much more of an uphill battle than for the NPC sororities.
I imagine that South Asian fraternities may face similar difficulties too. And if there are other South Asian fraternities, then there is the added challenge of differentiating your org from the others. "Unfortunately"

, since you are probably recruiting from a pool of students that doesn't know that much about what fraternities are, you are going to have a higher percentage of "fobs" than the IFC/NIC fraternities.
The South Asian fraternity on my campus was pretty well respected. They had some guys that spoke with accents but they still had a good reputation (and did well with recruitment) because they exemplified what Greek Life should be about. They won awards at Greek Oscars. They did a lot of community service. They did well academically. They had brothers on MGC exec board. They made an effort to have events with other orgs in MGC (not just socials but also community service projects).
Another thing that they did that was impressive was their dances. Every year, there is an Asian Awakenings show (different Asian orgs perform dances, songs, or skits). The guys in the South Asian fraternity always put on an awesome performance every year.
