Q1 Answer To apply for the Reciprocal Agreements budget, the applicant shall register on-line as STSM   https://e-services.cost.eu/w3/   https://e-services.cost.eu/stsm and specify that the STSM type as RECIPROCAL. The MC has to evaluate the application and send the complete application with the approval at least 6 weeks in advance, as the application has be reviewed by the SO and the COST Director. If the application is approved, I will process the confirmation documents and the grant will be paid after the mission, as per the rules. In this way, the Action budget will not be affected, as the STSM under the Reciprocal Agreements are funded by the Director's budget!
