There are three levels of membership in the International Association of Scientologists:

Free Six Month Membership It is valid for six months and has no fee.
Annual Membership It is valid for one year from the date of issue.
Lifetime Membership Valid for the duration of a person’s lifetime.

IAS Monthly Supporter: This is a system whereby someone can make automatic monthly membership payments or donations to the IAS. You can either enroll to simply make contributions of your choice at whatever time you want, regardless if you are already a member or not. Or, you can sign up for this program to make monthly payments towards your membership fee if for some reason you cannot pay the full amount now. By doing so, you will help make a difference every single day while paying towards your next membership.
