P petitions for essential support personnel are organized as other petitions, but with fewer documents. These include the alphabetized beneficiary list, itinerary, and any contracts, together with at least the petitioner's statement in the accompanying letter briefly describing a) the position and skills of each beneficiary; b) the beneficiary's past relationship, if any, to the group; and, c) stating why the beneficiary's services are essential. This can become somewhat burdensome if there are many such personnel.
