Catholics perform confirmation. Also, Lutherans do. This is done by the bishop or pastor.
The bishop is the one who performs it.
Why is it necessary, is one such question. Another one is who performs this Sacrament.
Often, a bishop or another clergyman with higher rank performs the Confirmation, but by delegation (If they are authorized to take over the confirmation for the bishop because he is busy with something else), an abbot or priest can also perform the Confirmation Mass.
The ArchBishop or Cardinal of a particular archdiocese is usually the one who performs Confirmation. A priest is the one who administers Baptism, First Holy Communion, & first Holy Confession.
Any consecrated church though in theory it could probably in extremis (in an emergency or extreme situation) be done anywhere which is suitable for it without things such as pagan idols etc. Confirmation can be given only by a bishop , sometimes a priest deputed by him could perform it, or a parish priest if he is baptising you during the Easter vigil and performs the confirmation during that vigil.
During Confirmation, the bishop performs several key actions. He lays hands on each candidate, invoking the Holy Spirit to strengthen them in their faith. The bishop then anoints the candidates with holy chrism, marking them as sealed with the gift of the Holy Spirit. This sacramental act signifies their full initiation into the Church and their commitment to living out their faith.
