Generally speaking, the population migration, and especially that of the workforce, has become a widespread phenomenon in Romania since the fall of communism, representing, maybe, one of the most important migratory fluxes at European level. Nowadays, when the economic crisis has hit Europe, when the majority of the developed countries perform a more rigorous control over immigration, they are the most affected by a slow down of the economic growth. This being due, mainly, to the industries in which immigrants are employed, or to the vulnerability of the type of jobs which are immediately put at risk by a negative change in the country's economic strength.
