The Polish researcher coming to Italy will have to get the money from the Banca d'Italia, i.e. the Italian National Bank. This means that the Polish researcher will get real money upon his/her arrival. Of course, the procedure has to be organized well ahead of time.
Applications for each visit of Polish researcher supported from the project may be submitted from January 15th until October 31st . The application must be submitted at least two months before the scheduled research visit. Research visits can take place only after March 15th and must end by December 31st.
