One of the circumstances human traffickers benefit from is the lack of knowledge, especially among young women, about actual possibilities of migration into Western European countries: they either have no or very little information about living conditions and employment opportunities in the European Union. They do not know their rights or if and how they can be issued legal working permits; they also do not know that they cannot work legally with tourist (Schengen) visa and are not aware of all the risks of working in the “black” labor market (ASTRA Anti-Trafficking Action 2009, 14)
