The My AmeriCorps Portal does not provide an immediate way to know whether or not the applicant received the invitation. Regardless of whether or not the applicant received the invitation, the applicant’s name will show up in your Invitation Workbasket. However, once the applicant completes Part I of the enrollment form, the applicant will appear in the Pending Enrollments Workbasket. If the applicant remains in the Invitation Workbasket for a long period of time, you should contact that applicant to inquire about their status.
