There are, in fact sororities that are geared towards southeast asian women. One of the biggest ones is Delta Phi Omega
http://www.deltaphiomega.org/ . If you feel that cutural would be a big issue (as you mention in your posts) groups like this would probably suit you more. Maybe you can even try alpha Kappa Delta Phi
http://www.akdphi.org/ , which is to date the largest asian sorority. Good luck!
