RCIA is also called the 'Catechumenate' and there are several stages and ritual steps leading up to the reception of the Sacraments of Baptism, Confirmation and the Holy Eucharist.

First Stage: The Pre-Catechumenate
Second Stage: The Catechumenate
The Third Stage: The Period of Purification & Enlightenment
The Fourth Stage: Period of Mystagogy

Becoming a Catholic is a big step; it is literally a life changing experience, and one which shouldn't be entered into lightly, nor should anyone ever feel pushed or coerced into becoming a Catholic because their fiancée is Catholic, or their in-laws expect it, or because it is easier to enrol children into Catholic schools. Like any family, it is always exciting and a great privilege to have new members arriving, thus there is no doubt that you are welcome, but this needs to be something that you believe God is calling you to, and should also be something that you desire for yourself as well.

The process seems long and perhaps even complicated, but it really is a great joy. It will undoubtedly be a special time in your spiritual life.
