You will want to post this on your local board. This is an international board. I, for example, living in Atlanta would have no idea where to send you. In addition, there is a Catholic Brides board, and they may be able to assist you in the rules of the Catholic Church.

Check your local, but you'll want to contact the parishes that you are considering directly. Catholic weddings must be performed in the church, so choose some churches you'd consider, and call them to find out whether they have membership requirements.
