For Alpha Gamma Delta, it is NOT a straight forward process- and from what I've heard, it is not easy nor does it always lead to gaining your membership back. However, it doesn't matter if Alpha Gam allows it- you will need to speak to Alpha Chi Omega HQ and find out your specific policies! I wish there was more to say, but each organisation dictates the terms of their membership, and we can't tell you where AXO stands. I wish you the best of luck, and I hope that you can work this out with your HQ!!
