you will probably have a sponsor who accompanies you on the journey while you are attending classes, sharing the scripture, and for the intial rites in the process. The godparent takes over at Easter (for those who have not yet been baptized). The sponsor you had for the first months of the journey may become the godparent at Easter (or the Confirmation sponsor for those already baptized) but you may choose a new person as godparent, if they qualify otherwise (not a parent of the candidate, not under canon law penalty, fully initiated Catholic adult living in accord with Church teaching, including laws on marriage). For children, the parents or another relative are often the sponsors for the first part of the process, and they choose the godparent or Confirmation sponsor for the initiation sacraments.
