The process is not the same as it is not the same thing.
RCIA is for converts. Sadly, many um-chatechised, Baptised only get put into RCIA because there is no other program.
In my diocese, that can be an option. So can one-one mentoring with a lay person, deacon or priest. Ultimately, it is up to the pastor to decide when the Sacraments are received.
Again, in my diocese, priests have been given permission to Confirm in the parish in certain cases.
