In recent years, in the European Union, migration of workers has increased considerably due to the opening of the Schengen area. Subsequently, many families are leaving Romania to work and live in Spain. The region of Castellón registers surprising numbers: 10% of the population is Romanian. Through what processes have these migration waves been built? The thesis proposes a reflection on family and individual modes of insertion of Romanians in the province of Castellón. The development of religious and family networks explains the continued growth of migrant flow from Romania to Spain. The notion of the path of migration allows observation of the complexity of the situation of migrants. Real territorial integration strategies can be analyzed. The entry integration of Romania into the European Union imposes a rethinking and a reinterpretation of the migration process. New concepts such as concurrency, glocalization, transnationalism allows for a reinterpretation of migration networks. The strategies adopted by families to ensure their survival are continually updated, as imposed by the current economic crisis in Spain.
