Does the hosting institution in Component I have to be a project partner?

The hosting institution does not have to be a project partner for a study visit to Component I. The application should only be accompanied by an invitation (scan) of the hosting institution from the Donor State accepting the scope of the visit, subject and number of participants, signed by the legal representative of the hosting institution. We do not impose an invitation form on you.
