No, the NIC, NPHC and NPC do not allow their members to be current or former members of another organization. I do not know about the LGLO and AGLO groups.

Service, honorary and professional GLOs are exempt from this. For example, I know a ZTA who is also a member of Sigma Alpha Iota, the music sorority.

Is it possible to be a member in more than one council? For example, a member of Phi Beta Sigma and Sigma Chi.
