Call or go to the church directly because in addition to needing the baptismal certificate and your residence address, each parish has different rules regarding classes and where and when they are held. If I remember correctly, classes start six months before and communions are held in May. Remember that we who write here are not related, nor are we paid, by the church or any other place where a user asks a question.
It is necessary to approach the Parish since the requirements depend on the Pastor.
