If you opt to make the contact fields required on an online recommendation or information request, the applicant will be required to provide an email address for the request contact. By entering an email address for a request contact, the request is automatically generated and sent. Therefore, you can make a request required to be sent by selecting this option. Additionally, you can require a request to be completed by checking the second option, Info Request Must Be Received to Submit Application.
Therefore, if you would like for the request to be completed and received in order for an applicant to submit their application, you'll want to select both requirement options. If you would like for the request to be required, but do not want to prevent an applicant from submitting their application until the request has been fulfilled by the request contact, you will select the first option (Contact Fields Required).
