Do Fulbright and Borlaug scholars need OVA?

Yes. Letters of invitation or (letters of intent from the host department) can be issued to applicants for Borlaug and Fulbright fellowships without processing an OVA first, but the letter itself should say that the invitation is contingent upon a fully executed and signed OVA. Should the applicant be selected for the Borlaug or Fulbright fellowship, the OVA visitor packet can be submitted by the host department at that time. The visitor packet will not include DS-2019 visa request.
