Greek life for international students

Engineering freshman here. I saw a lot of people talking about Greek life at GT. I'm interested in the academic/career resources and connections, and I'd like to know more about how it actually works. What are some of the typical activities and benefits of being a sister? The culture and vibe of international students can be pretty different from students in the US, so is it hard for international students to join a sorority? What are some of the suggestions/recommendations if I wish to join? Also, can I have similar connections and academic support from peers and alumni if I choose not to rush? Thx
