If you are an active member of one of the above societies, complete the Affiliate Membership Application Form, including the endorsement of two active members of the LAD (they may be Affiliate members, but not AAS Junior or Associate members).
If you are not an active member of one of the above societies, you may nevertheless apply for affiliate LAD membership by requesting the LAD Committee to consider membership in a non-recognized society instead (If you are not an active member of a related professional organization, enter notation "No Active Affiliation" in lieu of a Society name). Please note, however, such waivers are usually reserved for applicants residing outside North America.
