Bellow are all the known Cambodian or Khmer Student Association in the United States. Usually students use KhSA for the short form of Khmer Student Association. Then add the university name at the end. CSA can stand for Cambodian Student Association.
However the Chinese Student Association most likely already taken that name. They are bigger and probably form the association before Khmer students. So using KhSA is the most unique name.

Most importantly, KhSA is here to promote the Khmer culture amongst the people presiding in the surrounding communities. This organization also seeks to promote, support, and inspire Khmer American students to attend a college or university, particularly the University of Washington." -- https://sites.google.com/uw.edu/khmer/about

United Khmer Students of UCLA
"United Khmer Students is a student-run organization dedicated to fostering a positive environment for Khmer students and Khmer culture at UCLA. The club serves to represent and be an active voice for the greater Cambodian community and to advocate for its relevant issues. Due to the lacking representation of Khmer people, UKS feels itself to be a necessary component within the UCLA community. UKS not only provides a social environment for Khmer and non-Khmer students alike but works towards creating a politically and culturally active space. The club is consistent with cultivating cultural education and traditions for its general membership as well as providing leadership opportunities for members to be involved within their communities."
