Welcome to Sigma Iota Rho Gamma Omega! This website is home to the very first online chapter of SIR, the national honor society for International Relations. Gamma Omega’s members are students of American Public University System. APUS students are mostly military and government workers, but many civilians also find APUS’ convenient online programs perfect for their schedules. Members of Gamma Omega find APUS’ online format advantageous to our mission of promoting International Relations within our community. Please feel free to explore Gamma Omega’s website for our latest updates around the world. If you have any questions, you can email us via the contact form. Thank you for your interest in Sigma Iota Rho Gamma Omega.
