The Sacrament of Confirmation is the means by which an individual, after due preparation, makes a mature public affirmation of their faith and commitment to the responsibilities of their Baptism and receives the laying on of hands by the Bishop. 

This Sacrament is available to all baptized members of the Church, whether or not their baptism was in the Episcopal Church or another Christian denomination.
Reception is the means by which a member of the Church, who has been confirmed in another Christian denomination, makes a public affirmation of their faith, receives the laying on of hands by the Bishop and is received as a confirmed member of the Episcopal Church.
Confirmation normally occurs once a year at the annual visitation of the Diocesan Bishop.
