PF: Do all eligibility rules apply to Ukrainian researchers?

All rules apply to Ukrainian researchers. Exceptions can only be made to the mobility rule if the concerned person is in the process of application for refugee status and subject to certain residence restrictions so that they cannot move freely from one country to another as written in the MSCA Work Programme 2023-2025, p. 121 - 122:

„Recruited researchers must comply with the following mobility rule: they must not have resided or carried out their main activity (work, studies, etc.) in the country of the beneficiary (for European Postdoctoral Fellowships), or the host organisation for the outgoing phase (for Global Postdoctoral Fellowships) for more than 12 months in the 36 months immediately before the call deadline… Compulsory national service, short stays such as holidays and time spent as part of a procedure for obtaining refugee status under the Geneva Convention are not taken into account.”
