Because of economic problems, political conflicts, and regional instabilities in the last thirty years, there has been a tendency for immigration especially from Africa, South America, Middle Asia, and Middle East. This process made countries define these movements as illegal migration, a fast growing problem that also affected Turkey mainly as transit country toward Western Europe, but also as target. Some immigration policies of the European countries encourage people to migrate into their countries because they are offering monetary aids to immigrants and accept asylum seekers without proper investigation. Yearly immigrant quotas of European countries make them a center of attraction and encourage people to immigrate. Not punishing illegal immigrants because of their entrance into the country illegally make precautions to prevent illegal immigrants useless, some countries solving this problem by providing later legal status to those whose status is illegal. Turkey is mostly a transit country because of its geographical location; because borders are difficult to control and because Turkey is the most democratic country in the region, while regimes changes and regional wars occurred in the countries located at the East and Southeast of the country. Corruption and gap in the authority of the governments, as well as economic problems make also people ready to fly away. It happens that illegal immigration organizations present Turkish people who are trying to migrate to European countries illegally as considered as terrorists in Turkey, in order to faster their acceptance. PKK/KONGRA-GEL terrorist groups provide security and false documents for the groups trafficking human beings from Asia and Middle East, and get a certain amount of share for each person transported. They also control such activities in Northern Iraq. Turkey is effectively arresting the traffickers, and intercepting the illegal immigrants, but international cooperation remains vital.
