If you are asked to be a sponsor (godparent) for the Sacrament of Baptism or a sponsor for the Sacrament of Confirmation, most parishes require that the proposed sponsor obtain a Sponsor certificate (also called a Letter of Eligibility) from the parish that they currently belong to and attend Mass on a regular basis.
Every parish has a form which may be completed by its parishioners, if they meet the requirements to be a sponsor. Some parishes (in which the sacrament is to be administered) have their own form, which they require to be signed by a priest of the parish of the proposed sponsor.
For additional information and requirements, please contact the Parish Office. Its office hours can be found on the “Contact Us” page (via the “About Us” scroll-down menu, at the top of each webpage).
