Foreign Researchers’ Support Guide is a small book prepared to help those who chose Portugal to develop research activities, particularly at the Universidade de Lisboa. Our strategy of mobility’s promotion at the Universidade de Lisboa is to welcome foreign researchers in order to guarantee a bigger competitiveness both to the country and to the state members of European Union (EU). Internal mobility at EU and politics of support in transference of competences from academic and scientific world to companies’ universe increases the dimension and visibility, allowing innovation and technological development. Our intention is to include some aspects of Portugal and to support researchers’ arrival in the country, as well as all their country change trial.
