Problem: Greece, together with Italy and Spain, is a major entry point for illegal immigrants trying to enter the EU. Illegal immigrants entering Greece mostly do so from the border with Turkey at the Evros River and the islands of the eastern Aegean across from Turkey (mainly Lesbos, Chios, Kos, and Samos). In 2012, the majority of illegal immigrants entering Greece came from Afghanistan, followed by Pakistanis and Bangladeshis. In 2015, arrivals of refugees by sea have increased dramatically mainly due to the ongoing Syrian civil war. There were 856,723 arrivals by sea in Greece, an almost fivefold increase to the same period of 2014, of which the Syrians represent almost 45%. An estimated 8% of the arrivals applied for asylum in Greece.
